Instructions for Application 1. Safety Precautions
Outline of Mitsubishi Circuit Breakers
1
Carefully read the safety precautions prior to use the circuit breaker correctly. Important safety instructions are given below. Strictly observe the instructions. Be sure to communicate these safety precautions to the end user. DANGER Do not touch the terminal area. Doing so can cause an electric shock. The earth leakage circuit breakers are designed to operate when the difference between leaving current and returning current exceeds the specified value. In the case shown in this figure, earth leakage is not detected. Therefore, never touch the two bare live parts. The circuit breaker will not operate upon occurrence of an electric shock.
[Explanation of warning symbols] DANGER
Incorrect handling of the product will result in a hazardous situation, such as death or serious injury.
CAUTION
Incorrect handling of the product may result in a hazardous situation according to circumstances.
Instructions for use
CAUTION
Earth leakage circuit breaker
When the circuit breaker automatically breaks a circuit, turn on the handle after removing the cause. Failure to do so may cause an electric shock or a fire. [Earth leakage circuit breaker] Ground the earth terminal of electrical equipment. Failure to do so may cause an electric shock or a fire. Press the test button to check the operation once a month or so. If the earth leakage circuit breaker is not turned off, it is out of order. Consult an electrician.
Instructions for maintenance
Instructions for installation
CAUTION The electrical work shall be performed by qualified personnel (electrical workers). Before performing wiring work, turn off the upstream circuit breaker, and ensure that no current is flowing through the circuit breaker to be wired. Failure to do so may expose you to shock hazard. When connecting any wire, tighten the terminal screw to the torque specified in the instruction manual. Failure to do so may cause a fire. When the model comes with insulating barriers as standard accessories, install the insulating barriers without fail. Do not install the circuit breaker in an abnormal environment with high temperature, high moisture, dust, corrosive gas, vibration or shock. Doing so may cause a fire or make the circuit breaker inoperative. Protect the circuit breaker so that foreign particles, such as dust, concrete powder and iron powder, and rain water will not enter the circuit breaker. Failure to do so may make the circuit breaker inoperative. [Earth leakage circuit breaker] When using an earth leakage circuit breaker for use only in single-phase 3-wire or 3-phase 4-wire systems, connect the neutral wire to the neutral phase without fail. If they are not connected, the circuit breaker may not operate in the case of open phase or overcurrent, thereby resulting in a fire. Connect the circuit breaker to a power supply appropriate to the rating of its body. Failure to do so may make the circuit breaker inoperative or damage it. Tighten securely the lead wire in the open phase to the neutral wire on the load side. If the wires are not connected, the open phase of the neutral wire cannot be detected. When there are two terminal screws for the neutral pole, tighten the screws alternately. Failure to do so may loosen the screws, thereby causing a fire.
CAUTION The circuit breakers shall be maintained by persons with specialized knowledge. Before maintaining, turn off the upstream circuit breaker, and ensure that no current is flowing through the circuit breaker to be maintained. Failure to do so may expose you to shock hazard. Retighten the terminals periodically. Failure to do so may cause a fire.

*1 The term “each phase” used for load current and harmonic current refers to phase 1, 2, 3 or N. However, the phase N is provided only on 4-pole circuit breakers. The term “between each phase” used for line voltage refers to between phases 1 and 2, 2 and 3, 3 and 1, 1 and N, 2 and N or 3 and N. However, voltage between phases 1 and N, 2 and N and 3 and N is applicable only on 4-pole circuit breakers. These circuit breakers measure the values every 0.25 sec. Therefore, even when a low order circuit breaker operates, operating current may not be measured. *2 Each maximum value is the largest value among values obtained from the start of operation (after the previous reset) to the present. *3 The integrated value of electric energy and the integrated value of reactive energy are stored upon occurrence of power failure and every 30 minutes, the fault current and the cause are stored upon occurrence of fault, the set values are stored when they are set, and other values are stored every 30 minutes in the nonvolatile E2PROM. *4 The demand time limit cannot be set individually. It is common to the items. *5 The average values of load current and line voltage are calculated as shown below when the phase and wire type is specified.

*6 Sum of values of harmonic components in third to 19th orders except fundamental wave component *7 The reverse power is not measured. *8 When leakage current does not contain harmonics, the leakage current value is measured after removing the harmonic components with a digital filter having the same cutoff frequency as the earth leakage circuit breaker applicable to harmonics and surge. *9 When a motor is used as a load, the maximum demand value of leakage current may be affected by the motor starting current. *10 If the upper limit of the fault current measurement range (rated current 125 to 250 A (adjustable): 4000 A, rated current 50, 60, 75, 100, 125 A (fixed): 2000 A)) is exceeded when overload or short circuit fault occurs, the cause of the fault may not be displayed, and the fault current may not be measured. For fault current, display of cause of fault and measurement of fault current are enabled when the AL for transmission with the Measuring Display Unit (option) is installed. *11 The leakage fault current value is the value calculated without harmonics. *12 When the alarm retention mode has been set to Automatic reset, the alarm display on the Measuring Display Unit will be reset automatically. When the alarm retention mode is Self-retention, the alarm display will be self-retained. In the self-retention mode, the display can be reset through the alarm reset operation (collective reset). OVER will be automatically reset regardless of the mode setting.

Notes: *1 The electric energy (integrated value) is stored upon occurrence of power failure and every 2 hours, the fault current and the cause are stored upon occurrence of fault, the demand time limit, EPAL sensitivity current, PAL pickup current, pulse unit, alarm retention and phase switching settings are stored when they are set, and other values are stored every 2 hours in the nonvolatile E2PROM. Each maximum value is the largest value among values obtained from the start of operation (after the previous reset) to the present. *2 Every time the electric energy is integrated in the pulse unit (the unit can be set to 1 kWh, 10 kWh, 100 kWh, 1000 kWh or 10000 kWh), a pulse is output. Counting can be performed with a PLC. *3 The term “each phase” used for load current and harmonic current refers to phase 1, 2, 3 or N. However, the phase N is provided only on 4-pole circuit breakers. The term “between each phase” used for line voltage refers to between phases 1 and 2, 2 and 3, 3 and 1, 1 and N, 2 and N or 3 and N. However, voltage between phases 1 and N, 2 and N and 3 and N is applicable only on 4-pole circuit breakers. The electric energy data is 6-digit data of up to 999999 kWh. The voltage and harmonic current are 3-digit data, and others are 4-digit. These circuit breakers measure the values every 0.25 sec. Therefore, even when a low order circuit breaker operates, operating current may not be measured. *4 Each general value indicates the value only of the phase with the maximum value. *5 The electric energy is not measured in the case of reverse power flow. *6 When the alarm retention mode has been set to Automatic reset, the PAL, EPAL, ECA alarm LED display on the Measuring Display Unit front panel will be reset automatically. When the alarm retention mode is Self-retention, the alarm display will be self-retained. In the self-retention mode, the display can be reset through alarm reset operation (collective reset). OVER will be automatically reset regardless of the mode setting. *7 The demand time limit cannot be set individually. It is common to the items. *8 Sum of values of harmonic components in third to 19th orders except fundamental wave component. *9 The average present value of load current is the average value of current among phases 1, 2 and 3 (the current of the phase N is not included even in the case of a 4-pole circuit breaker). When the circuit breaker is used on a single-phase 3-wire circuit, the calculated value is displayed. However, ignore it. The average present value of line voltage is the average value of voltages between phases 1 and 2, 2 and 3 and 3 and 1 (the voltages between phases 1 and N, 2 and N and 3 and N are not included in the case of a 4-pole circuit breaker). *10 Setting at the pre-alarm current Ip (which can be set in the range from 70 to 100% of the rated current In in 5% steps) on the circuit breaker body.

䊉Cautions when Using Measuring Display Unit Breakers (common instructions) Measuring accuracy
How to use Measuring Display Unit Breaker on single-phase 2-wire circuity (1) Connect the breaker as shown in the right figure. Connection on single-phase 2-wire circuit The phase 1 on the load side is charged. Insulate it. 1 2 3 As measurement data, use the current of the phases 2 and 3 and the voltage between the phases 2 and 3. Line side Although the current of the phase 1 and the voltage between the phases 1 and 2 and the phases 3 and 1 are measured, ignore the measurements. The Measuring Display Unit is designed for 3-phase 3-wire and single-phase and 3-wire circuits. On W & WS Series Measuring Display Unit Breakers, the average values of load current and line voltage are calculated from the values of the phases 1, 2 and 3 (between the Load side phases). Ignore these measurement values. ATTENTION: Live part Load Also when the breaker is used on a single-phase 3-wire circuit, ignore these values. When using any WS-V Series Measuring Display Unit Breaker, set the phase and wire type.
Phase sequence of Measuring Display Unit Breaker The phase sequence of Measuring Display Unit Breaker can be set by using the phase switching function as shown below. When the breaker is installed vertically with the power supply side upward (see the right figure), the phase sequence is set as stated below. No phase switching: 1, 2, 3 and N from the left (default) With phase switching: 3, 2, 1, and N from the left Set the phase sequence in accordance with the installation and wiring methods. Notes (1) The phase N is provided only on 4-pole circuit breakers. Notes (2) Note that the position of the phase N is unchanged regardless of the phase switching setting.
Reverse connection of Measuring Display Unit Breaker The Measuring Display Unit Breakers cannot be connected with the power supply and load sides set reversely.

(1) The accuracy of measurement of current or voltage is indicated as the percentage of error to the rated current or voltage for measurement by the Measuring Display Unit. The measurement rated current is the maximum rated current of each ampere frame. For W & WS Series Measuring Display Unit Breakers, the accuracy is the max. rated current × ±2.5%. For WS-V Series Measuring Display Unit Breakers, the accuracy is the max. rated current × ±1%. (For example, when the rated current of NF630-SEP with Measuring Display Unit is 350 A, the measurement rated current is 630 A, and the current accuracy is 630 A × ±2.5% = ±15 A.) However, the measurement rated current of the following breakers is determined as follows.
䉬Rated current 50 A, 60 A, 75 A, 100 A, 125 A: Measurement rated current 125 A 䉬Rated current 125 to 250 A: Measurement rated current 250 A * The measurement rated voltage is 440 V. (Common to all A frames) When the current is less than 1.0% of the measurement rated current in the case of WS-V Series Measuring Display Unit Breakers or less than 2.0% of the measurement rated current in the case of W & WS Series Measuring Display Unit Breakers or when the voltage is less than 5.0% of the measurement rated voltage in the case of WS-V Series Measuring Display Unit Breakers or less than 2.0% of the measurement rated current in the case of W & WS Series Measuring Display Unit Breakers, the current or voltage is cut off, and zero is displayed. (2) When the current is cut off, the current is displayed as 0 A. However, if the current is 0.4% or more of the measurement rated current, the electric energy is measured. (3) The accuracy of power factor is the percentage to electrical angle of 90°. A power factor of 50% or less is displayed as a reference value. (4) The accuracy of electric energy is ±2.0% of the true value in the case of WS-V Series Measuring Display Unit Breakers and ±2.5% of the true value in the case of W & WS Series Measuring Display Unit Breakers in the range of measurement rated voltage (100 V to 440 V) × current (measurement rated current of 5 to 100%). (5) The accuracy of leakage current is ±2.5% of the measurement rated current of 500 mA.

In poles equipped with a shunt tripping mechanism, the overcurrent tripping element is not operative (switched shunt tripping). For back-face wiring terminals, specify if it will be used with 30A, or 20A or less. UL(cURus), CCC, and CE Marking are displayed on standard products. It is recognition of UL(cURus), CCC, and TUV. In case of DC use, only DC65V is available. Specify if for DC use when ordering. Specify when ordering. (In case of CP-S UL, type name is CP-SU.) Connection is male tub terminal only. CP30-BA only.
Remarks: 1. Products for non-standard conditions are special order. (Low temperature, 1st and 2nd-degree moisture fungal treatment, corrosion-resistant) 2. Although a buzzing sound may occur when an instantaneous type becomes 80% or more of the rated current for AC use, performance is not effected. Please take this point into consideration when selecting units for use in quiet environments. 3. Please use in environments free of high temperatures, humidity, dust, corrosive gas, vibration, and impact. Also, do not use it in a circuit with inrush current or harmonics. Problems may result.

The operating characteristics of electromagnetic (instantaneous) type circuit protectors are not affected by the installation posture. However, when installing a fluid electromagnetic (high, medium or low speed) type circuit protector, pay attention to the installation angle because the operating current value is changed under the influence of the gravity applied to the iron core in the oil dash pot. Generally, it is recommended to use the circuit protectors in the vertical direction.

Breaking is more difficult with direct currents because the current value never reaches zero. While ordinary DC breakers are suitable for low voltages, special-voltage DC breakers are recommended for voltages in excess of 250VDC. Breakers for 550V are all 4-pole models. The size, shape, drilling plan, accessories, etc., are all identical to the S Series breakers with the same designations.
Remark: 1. The tripping characteristics will change if the wiring differs from the one shown here.

qTime-delay trip function This function conforms to the allowable current and time characteristics of electric wire and prevents operation caused by the staring current of a load device. When the overcurrent is large, the operating time is short, and when the overcurrent is small, the operating time is long. In the case of electronic type The electronic time-delay trip function includes a long time limit trip function conforming to the allowable current and time characteristics of conductor and a short time limit trip function for selective breaking for branch NFB. The short time limit function operates after a delay of some cycles (0.06 to 0.3 s) at overcurrent exceeding the short time limit tripping current. These functions can be adjusted by the knob. wInstantaneous trip function This function breaks the circuit immediately when shortcircuit current flows. A circuit breaker on which the instantaneous tripping current is adjustable has the advantage that coordination in operation with other protective devices, such as electromagnetic switches and low-voltage air circuit breakers, can be easily obtained. The instantaneous operating time (total interrupting time) can be divided as shown in Fig. 4-10. eOperating characteristic curve The operating characteristic curve indicates the relationship between magnitude of overcurrent and operating time. The maximum-minimum operating characteristic curve indicates that the operating time is in the range. Figs. 4-11 and 4-12 show examples of operating characteristic curves.

Motor Protection Breakers The motor protection breakers are circuit breakers to be used to protect general induction motors. They prevent motors being burnt not only by short-circuit current of circuits, but also by overcurrent caused by overload operation and locking of motors. The Motor Protection Breakers are finely classified according to rated current so that the breakers can be applied to various types of motors. Although their time-delay trip and instantaneous trip functions are almost the same as those of MCCB, they are designed to operate within 2 seconds to 30 seconds at 600% of the rated current in consideration of protection from motor starting current and locked current.
66
There are many kinds of motors, and the motors have various allowable characteristics for overcurrent. Therefore, when applying a motor breaker, it is necessary to compare the allowable characteristics and the operating characteristics of the motor breaker. Note that, particularly, submersible motors may not be protected by ordinary motor breakers because their allowable locked time is short. When the motor starting current is large and the starting time is long and when the frequency of intermittent operation is high, motor breakers are unsuitable. In such a case, the use of a combination of an electromagnetic switch and MCCB (combination starter) is recommended.
4 Selection 2 Selection of MCCB and ELCB
Characteristics of MCCB for DC circuits When a 2-pole MCCB (250 V DC or less) is used on a DC circuit, connect the poles in series. When a 3- or 4-pole MCCB is used, refer to page 60 (for special DC voltage) or pages 14 to 21 (for DC). If the breaker is not connected as specified, its tripping characteristics and breaking performance will change, and it cannot be used.
Current-limiting characteristic Current
The current limiting refers to reduction of estimated short-circuit current depending on the circuit to prevent flow of the larger short-circuit current. The use of a class S, H or R which has excellent current-limiting characteristic or class U enables to reduce the passing energy at shortcircuiting and protect the devices in the electric circuit from electromagnetic force and thermal stress.

Table 4-2 shows the durability against opening and closing. See the durability against opening and closing as reference when using a circuit breaker as a switchgear. The durability against tripping by SHT (shunt tripping device), UVT (undervoltage tripping device) and trip button is 10% of the total durability against opening and closing. Note: Opening and closing operations are regarded as one time. If a circuit breaker is regularly used to trip, the life of the circuit breaker will be significantly reduced.

3. Current-carrying Capacity and Operating Temperature Operating current vs. ambient temperature Rated current of circuit breakers is adjusted for the rated ambient temperature. This is because circuit breakers are often installed in a casing as a switchboard or a control board, and temperature of the installed place of the breaker becomes higher than ambient temperature of the wires. If temperature of the installation site of circuit breakers greatly differ from the rated ambient temperature, it is necessary to correct rated current according to the temperature correction curve (shown in the Paragraph of characteristics and outside shape in the catalog). Load current can be increased up to the rated current corrected according to ambient temperature. However, set current rating with enough allowance while taking fluctuation of power voltage and load current into consideration so that maximum operating current may not exceed the rated current.

For using insulated wires of higher heat resistance than that of 600 V PVC insulated wire (allowable temperature 60°C), it is necessary to take the following points into consideration. For circuit breakers, size of test wire is stipulated by each test current in IEC60947-1 If size of connection wire is thinner than the test wire size, temperature of the breaker terminals increases and overcurrent tripping operation characteristic may change in some cases. (Operating time becomes shorter usually.) At motor load, for example, influence of change in operation characteristic by difference in size of connection wire is insignificant and can be disregarded because the load current is far lower than the rated current of the circuit breaker.

(2) Connection of aluminum conductors • When aluminum conductors are connected, be careful to prevent the contact resistance (due to the oxidized film of aluminum) from being increased. • The surface of the connection point of the aluminum conductors shall be properly treated by plating (zinc displacement-Copper-Silver) or by joint compound. If the treatment is done only by joint compound, reliability is low, this should be limited to when plating is impossible (eg. at site). • For aluminum cables, use compression terminals that are exclusively for aluminum cables. • The compression portion of the terminal shall be provided with taping, and the aluminum wire shall not be exposed to the atmosphere.

Remarks: 1. Fot the rated curent in parentheses, breakers will be manufactured to order. 2. The approximate values of inrush current at direct-to-line starting are shown below. Up to 7.5 kW: 1000% 11 kW or more: 1200% 75 kW or more: 1400% When the starting current is large and the starting power factor is low, a combination with an electromagnetic switch selected in accordance with “Table of selection of circuit breaker for motor branch circuit” shown on page 73 is suitable. Cautions (1) Note that any circuit breaker operates when the startup inrush current, starting current and starting time exceed the conditions shown in the above table. Particularly, high-efficiency motors generally have higher starting current and lower starting torque compared to general-purpose motors, and motor breakers cannot be used for such motors. (2) Note that a circuit breaker may operate when an electromagnetic contactor is opened or closed while a motor is running. (3) Select a motor breaker having rated current approx. 1.0 to 1.1 times higher than the full load current of motor.

Remarks: 1. Circuit breakers for harmonics and surge can detect earth fault on the secondary side of inverter only when the operating frequency is 120 Hz or less. In the case of star connection by neutral point grounding method, the sensitivity current for earth fault on the inverter secondary side is degraded. In this case, for protective ground for load device, apply Class C grounding (10 Ω or less). 2. For general circuit breakers, the leakage current from the line between inverter and motor shall be calculated as three times the leakage current at the commercial frequency in consideration of harmonic content. 3. For the model names of circuit breakers for harmonics and surge, refer to the specification list in Section 2 of this document. Models not for harmonics and surge are general breakers.

9. Selection of Circuit Breaker for Transformer Primary Side Notes 1. The life cycle of the circuit breaker for the circuit on the transformer primary side will be significantly reduced under the influence of excited inrush current. Install a switch to open and close the circuit. 2. Select a circuit breaker based on the example of excited inrush current of each transformer. When using a circuit breaker for a transformer, check the magnitude of excited inrush current with the transformer manufacturer.

Notes *1 Examples of selection of high-instantaneous circuit breakers (special models) for primary side of transformer. *2 The circuit breakers with rating in parentheses are special models. Remarks: 1. For the circuit breakers whose rated current is adjustable, the rated current values are shown. 2. The peak value of the first wave of excited inrush current shall be calculated based on the multiple for the peak value of the first wave in the table, and the calculated value shall not exceed the lower limit peak value of instantaneous tripping current of circuit breaker. The circuit breakers are selected on condition that the transformer rated current value does not exceed 0.9 times the circuit breaker rated current. If the multiple for the peak value of the first wave is different from that shown in the table, a circuit breaker must be separately selected.

Note *1 Rated currents of branch breakers are 50A or less. Remarks: 1. It is considered that the instantaneous tripping characteristic values of main circuit breakers have been set to the maximum values. 2. For the selectivity in the overcurrent range, separately check the coordination on the operating characteristic curve.

12. International Standard Comformance List 12.1 UL and CSA Approval Product UL (Underwriter’s Laboratories) Standards: UL 489, UL 1077 UL is an organization in the US which establishes safety standards, i.e. UL Standards, conducts safety verification test based on the UL Standards, issues the certificates to approved products and allows the manufacturers to attach the certification mark to the products. The UL certification mark has been spread widely in the US. Some states and cities oblige manufacturers to receive the UL certification. When devices, control panels and machines are exported to the US, these products must be UL certified. UL certified products have received UL Recognition or UL Listing in conformity to UL Standards (UL 489, UL1077) and allowed to be used in control panels and machines to be exported to the US. : UL Recognition Refers to component certification for products designed to be built in other products and devices. UL recognized products can be used in control panels, machine tools and control units.
: UL Listing Refers to product certification for products which can be sold directly to end-users and used by end-users. These products can be used also as built-in components in control panels, machine tools and control units. Some models vary in external dimensions and terminal structure from standard models. Please refer to the page of UL listed products for details.
CSA (Canadian Standard Association) Standards: CSA C22.2 No.5-02
: Recognition for US and Canada UL and CSA recognition of components by testing body UL
: Listing for US and Canada UL and CSA recognition of components by testing body UL
12.2 CCC (China Compulsory Certification) Approval Product Low-voltage circuit breakers are designated as products to be compulsorily certified in China. To export such products to China and sell them in China, it is necessary to obtain the CCC certification.
12.3 Corresponding to EC (European Community) Directive Corresponding to LVD (Low Voltage Directive)
aWhen using a low voltage circuit breaker as a component and indicating conformity with the EC Directives The CE Marking is required when a low voltage circuit breaker is distributed as a single device in EU. However, when the CE Mark is indicated on a machine tool or a control unit, it is unnecessary to affix the CE Mark to the low-voltage circuit breaker used as a built-in component. When the CE Mark is indicated on a machine tool or a control unit, it is recommended to use a product certified by a third party shown in Item d (TÜV certified product) as a low voltage circuit breaker. sMeasures for export of low voltage circuit breaker as single unit When exporting a low-voltage circuit breaker as a single unit in EU, the circuit breaker is covered by the Low Voltage Directive. The certification of conformity with the Low Voltage Directive is self-declared as a rule. The applicable product standards are shown below. EN 60947-2 Low-voltage switchgear and controlgear-Part 2: Circuit-breakers EN 60934 Circuit-breakers for equipment (CBE) dModels certified by third party (TÜV certified products) When the CE Mark is indicated on a machine tool or a control unit, it is recommended to use a low voltage circuit breaker certified by a third party (TÜV certified product) as a built-in component.
Corresponding to EMC (Electromagnetic Compatibility) Directive The Directive prescribes that products shall not emit high-intensity radio waves to the outside and shall not be affected by external electromagnetic waves. Molded case circuit breakers (electronic type) and earth leakage circuit breakers are covered by the EMC Directive.
Corresponding to Machinery Directive Low voltage circuit breakers are components used in equipment, such as machine tools and control units, and are not covered by any machinery directive. When the CE Mark is indicated on a machine tool or a control unit, it is recommended to use a low voltage circuit breaker certified by a third party (TÜV certified product) as a built-in component.

The CSA Standards are product safety standards established by CSA. In Canada, the safety of electric products is regulated by the state laws, and some state laws prescribe that circuit breakers shall be certified by the CSA Standards. Therefore, when devices, control panels and machines are exported to Canada, these products must be CSA certified. UL certified products have received CSA certification from the testing body UL and allowed to be used in control panels and machines to be exported to Canada. UL has been authorized as a testing, certification and quality certification body by SCC, and CSA certified products tested by UL have been approved by the safety regulations in all states of Canada. It is allowed to attach the following certification marks to products certified by both UL and CSA. (It is also allowed to attach the separate marks for the US and Canada as before.)

4. Earth Fault Protection Coordination and Combination of Devices Table 4-28 Protection type With selectivity only for earth fault breaking
With selectivity for earth fault breaking and cascade type of short-circuit breaking With selectivity for earth fault breaking and short-circuit breaking
Details 䊉On general lines, the protection grounding resistance is relatively large and the earth fault current is small. In this case, install a time-delay relay on the main circuit and a high-speed relay on a branch circuit. 䊉The selectivity for earth fault breaking is as stated above. 䊉Significant short-circuit fault very rarely occurs because of its nature (in most cases, circuits are broken at the early stage of earth fault). This protection is applied when the continuity of power supply is expendable. (Refer to the combination for cascade breaking on page 83.)
Installation point
䊉This protection is applied when selectivity is necessary in the entire area of fault. (Refer to the combination for selective breaking on page 81.)

6. Insulation Distance on Power Source Side 䊉Basic concept
Insulation distance (distance indicated in standards) Be sure to at least secure the insulation distances (spatial distance and creeping distance) specified by the codes and standards of the relevant equipment and facilities where the circuit breakers are installed. It is recommended that insulation barriers and insulation tape be used to enhance the electrical insulation between bare-live parts and between bare-live parts and ground to avoid accidents otherwise caused by a loose metal piece, conductive dust, abnormal surge voltage in the circuit or a similar event so as to improve the reliability of panels.
Arc Space (insulation space) At the exhaust outlet side of breaker, arc space is necessary. When the actual load circuit is opened, especially when a large current such as overload or shortcircuit is interrupted, ionized gas is emitted from the exhaust outlet. This gas can cause a short circuit between bare, live parts such as busbars, and also can cause grounding faults between conductive installation metal panels. Therefore, it is important to secure enough arc space at the exhaust outlet side of the breaker and to strengthen insulation of parts exposed to the gas. In addition, securing enough space at the front of the exhaust outlet is necessary, because when the gas emission is blocked, failures such as deterioration of breaking performance can be caused.
䊉Insulation required part
With regard to insulation of bear, live parts of the line side of the breaker, please make sure to insulate at least C part C indicated in the diagram above with insulation tape, a tube or a terminal cover. qA : Distance from the circuit breaker to the ceiling plate wB1 : Distance from the circuit breaker to the uncovered conducting part of the upper circuit breaker terminal (front connection) eB2 : Distance from the lower circuit breaker to the end face of the upper circuit breaker (rear connection) rD1 : Distance from the side of the breaker to the side plate tC : Insulated length of the power source terminal of the circuit breaker (front connection) Please secure insulation using insulating tape, insulating tubing, insulation barrier, or a terminal cover, between bare charge parts within this size range. Please refer to a table a necessary size must. 䉫When using insulation tape and insulation tubing together with insulation barriers and terminal covers, make them overlap with the other by at least 10 mm. 䉫For the models with insulation barriers supplied as standard, please make sure to use the barriers. a : clearance specified in standard yD2 : Side-to-side spacing of breakers While the circuit breakers can basically be installed together without a clearance in between, be sure to observe the following instructions. 䉫It is desirable to install an insulation barrier between the adjacent circuit breakers or insulate the bare-live parts considering the effect of cutoff gas. 䉫Be sure to secure the insulation distance (dimension a) as the minimum, indispensable requirement. 䉫With a leakage circuit breaker and a leakage alarm circuit breaker installed in close contact with the other, a current of 2,500A or higher flowing through one of the circuit breakers could cause the other to operate falsely. Be sure to secure a distance of at least 50 mm in between. 䉫A circuit breaker of 400-ampere frame or larger with an SHT or a UVT could operate falsely if a current of 50 kA or higher flows through the adjacent circuit breaker. Be sure to secure a distance of at least 50 mm in between. D2

7. Effect of Installation Orientation Installation orientation does not affect the operating characteristics of circuit breakers of electronic or thermomagnetic operation types. However, the installation orientation affects the operating current of fully magnetic type circuit breakers as the iron core in the oil dash pot is under gravitational force. It is generally suggested they be installed vertically. 䊉Hydraulic-magnetic (The same applies to other models of hydraulic-magnetic type.) MCCB Class C

The second AX can be installed in place of the AL on the left pole side. When placing an order, specify the incorporation of the switches in the body. Although the lead wires are normally drawn out laterally, those with lead wires drawn out toward load are available. (Only for front connection type) PAL (contact output) can be installed together with AL and AX on the left pole side. (It cannot be installed together with SHT or UVT.) The standard type is provided with SLT. PAL control voltage (compatible with 100 to 200 V AC) is necessary. SHT and UVT can be installed on the left side. SHT and UVT are normally installed on the right pole side. If you intend to install them on the left pole side, specify so. (The reset preventing UVT must be installed on the left pole side.) In the case where three or more accessories are installed on the left pole side and AL, AX or AL and AX are installed on the pole on which SLT, SHT or UVT is installed, the SLT will be manufactured to order. When AL, AX or AL and AX are installed on the pole on which UVT is installed, the UVT voltage module must be installed separately. SLT is provided as standard. A control power supply (100 to 200 V AC) is required. (In this case, other internal accessories cannot be installed on the right pole side.) 1. For electrically operated automatic reset type circuit breakers having a frame size of 400A or above, the numbers of AL switches which can be installed are smaller by 1 than the values shown above. 2. The encircled numbers indicate the order of installation.

Procedure for installing cassette type accessories
1. Press the trip button (PTT) to trip the circuit breaker. (*1)
2. Loosen the cover screws.
3. Open the cover.
4. Install the cassette type accessory. (*2)
5. Close the cover, and tighten the screws.
Notes *1. When installing any cassette type accessory, set the circuit breaker to the tripped state. *2. If the inner lid or another accessory has been installed, remove it before installing the accessory. When any circuit breaker supplied with the inner lid is used without an accessory, fit the inner lid without fail. Failure to do so may affect the short-circuiting performance. Models with inner lid: NF125-SV, NF125-HV, NF125-UV NF250-HEV, NF250-UV NV125-SV, NV125-HV NV250-HEV NF250-SV, NF250-HV, NF125-SEV, NF125-HEV, NV250-SV, NV250-HV, NV125-SEV, NV125-HEV, NF125-SVU, NF125-HVU, NV125-SVU, NV125-HVU NF400-REW, NF400-UEW NF250-SVU, NF250-HVU, NV250-SVU, NV250-HVU NF630-REW, NV400-REW NF800-HEW, NF800-REW, NF800-UEW NV800-HEW
Cautions when installing Before installing or removing any cassette type accessory, set the circuit breaker and accessories to the no-voltage state. Never install a cassette type accessory while the handle is in the ON or OFF position. Doing so may damage the accessory. When installing an accessory with lead wires drawn out, apply the supplied nameplate to the circuit breaker side face. When installing an accessory with lead wires drawn out for a frame size of 400 to 800 A, secure the lead wires along the circuit breaker side face with the supplied lead wire retainers.

Some special voltage models vary in voltage range. The operating time is the time from when the undervoltage tripping device is set to the no-voltage state until the main contact starts opening. The accessory is usable at 50 Hz and 60 Hz. If UVT is turned on without excitation, the circuit breaker instantaneously opens and immediately trips. Only for installation on the left pole
(2) Reset type and non-reset type UVT
1 Accessories
6
Reset type (Refer to Table 6-12.) The reset type UVT has a structure which does not trip a circuit breaker even if the UVT coil is not excited when the circuit breaker handle is in the OFF or reset position. Therefore, it keeps the circuit breaker in the reset state even if the coil is not excited when the breaker is reset electrically. When the coil in the unexcited state is turned on, the circuit breaker is normally tripped. However, the major contacts of some models of circuit breakers may instantaneously close, or, on circuit breakers with AX, the AX switches may instantaneously change over. For electrical interlock, use a non-reset type UVT. Non-reset type (Refer to Table 6-12.) When the UVT coil is not excited, the circuit breaker cannot be set to the off state even if the circuit breaker is tried to be reset from the tripped state. When the coil exciting voltage restores to the reference voltage or more, the circuit breaker can be reset to the off state.
(3) Time delay UVT ● This type of UVT has a time delay in operation. ● It can prevent operation upon occurrence of instantaneous power failure. Table 6-12 UVT module type name

(4) Structure of UVT The UVT mechanical unit is installed in a circuit breaker, and the UVT voltage module is installed on the outside of the circuit breaker. When the voltage drops, the UVT voltage module detects the voltage drop, and the UVT mechanical unit trips the circuit breaker. The UVT voltage module has a vertical lead wire terminal block and is normally installed on the body. The external module will be manufactured to order. ●Outline drawing D

Lockout hasps (scissors locks) can be used. If the circuit breaker trips even when the operating handle is locked in the ON position, also the operating handle indicates that it has tripped. F-2SUL or below: Only when one 35-mm padlock (weighing 70 g or less) is used F-4S or above: Only when one 40-mm padlock (weighing 100 g or less) is used To 800A frame or below, padlocks with dimension C of 3 mm to 8 mm can be applied. For 1000A or above, padlocks with dimension of 3 mm to 6 mm can be applied. (When using padlocks of 3 mm or less, please consult us.) Circuit breaker installation direction (except UL 489 listed circuit breakers) We can supply circuit breakers on which the handles and their ON and OFF positions are in the same directions as on vertically installed circuit breakers even when they are installed horizontally. The door drilling size is identical. If you intend to install an operating handle on a horizontally installed circuit breaker, specify “Y” (horizontal installation with power supply on the left) or “Z” (horizontal installation with power supply on the right) at the end of the model name.

The terminal covers are used to avoid exposure of live parts. Many kinds of terminal covers, including large terminal covers (TC-L), small terminal covers (TC-S), transparent terminal covers (TTC), rear terminal covers (BTC) and plug-in terminal covers (PTC), for various models and applications are available, and they are helpful. (The terminal covers cannot be fitted to electrically operated circuit breakers of spring charged type (2) and motor-drive type (2). The standard terminal covers can be used for the spring charged type (1). For the motor-drive type, special terminal covers can be manufactured. Consult us for details.) Quick terminal covers These covers are very convenient because they can be fitted only by inserting them into the mounting holes in the circuit breaker body. To remove the terminal cover, shift the projections of the terminal cover with the tip of a slotted screwdriver or finger, and draw it out.

Specify the circuit breaker mounting pitch (P). No need to specify the panel thickness (t). (Usable panel thickness range: t = 1~3.2mm. Above 400AF, use panel thickness t = 1.6~3.2mm) For isolation purposes with 400, 600, 630 or 800A frame NF-SKW/SLW or NV-SKW, keep the C dimension deviation within ±1 mm. Terminal covers cannot be fitted. (However, TCL-4SW3 can be fitted.) Not UL 489 listed product. When UVT is provided, separately install the module. If the thickness is not 2.3, specify the panel thickness (t). For NV with TBL, use a circuit breaker with MG. 1. When a mechanical interlock is installed on the panel, screw type terminal covers cannot be installed. 2. These devices do not provide an isolation function. However, 400, 600, 630 and 800A frame circuit breakers can be made conforming to it. (See Note 3.) 3. On a 2-pole circuit breaker obtained by removing the neutral pole conductor from a 3-pole circuit breaker, the mechanical interlock can be installed in the same manner as on a 3-pole circuit breaker.

The window frame varies depending on the model. For 1-pole circuit breakers, boxes are not manufactured. The protection class of NFI-1SV and NFI-2SV is IP3X. The protection class of NFW-4CW, NFW-4SW, NFW-6SW and NFW-8SW is IP54. The circuit breaker body is a 2-pole external type. 1. Only internal accessories with lead wires drawn out can be fitted. (However, LT and SLT can be fitted on the right pole side.) 2. The dust-proof type (I) models do not provide an isolation function.
Selection of rated current When selecting the rated current of circuit breaker, it is necessary to consider the temperature in the box. When the rated current is carried, the temperature in the box increases by 10 to 20K. Correct the rated current with the temperature correction curve. Determine the maximum working current to be 80% or less of the rated current.
Interlock (only for Dust-proof type) The cover cannot be opened while the circuit breaker is in the ON state. However, if the interlock release screw is turned, the cover is released from the locked state and can be opened even in the ON state. Handle operation and display The ON, OFF or trip state of the body is displayed on each position on the decorative board.
Locking Type I and W boxed circuit breakers can be provided with locks in the following parts. Locking can prevent unnecessary operation. qCover and case wON or OFF position of operating handle Padlocks must be prepared by the user. The dimensions of the padlocks are shown on page 116.

Notes *1 When the rated operating voltage is 24 V DC or 48 to 60 V DC, specify the voltage. If the voltage is not specified, the circuit breaker will be manufactured for 100 to 240 V AC and 100 to 250 V DC. *2 For 24-V DC circuit breakers, the operating time at a voltage of 100% or more is shown. *3 Models for special voltage (125 V DC or 240 V AC) are not provided with the test button. Remarks 1. Flush plate type circuit breakers can be manufactured to order. 2. The models with voltage in parentheses are special voltage products. 3. For the spring charge type (1), use an ON-OFF operating switch for minute load. 4. For the spring charge type (1) with 3 poles, TC-S, TC-L, TTC, BTC and PTC can be used. For that with 4 poles, only TC-L can be used. 5. When the body of the spring charge type (1) breaker is an earth leakage alarm breaker, the reset button cannot be pressed. Provide such a circuit breaker with an external reset or automatic reset system (except for the electronic type). 6. When the body of the motor-drive type (2) or spring charge type (2) has internal accessories, they are normally provided with lead wire terminal blocks. 7. The types other than the spring charge type (1) do not provide an isolation function. 8. When placing an order for a CE marked product of the spring charge type (1) or spring charge type (2), specify the model name with CE. 9. The switching durability of electrically operated circuit breakers conforms to JIS.
Electrical operation devices
The following models of Electrical Operation Devices are supplied also as separate devices. The user can install them to the circuit breaker body. (Front connection, rear connection and plug-in types) (When requiring a motor breaker or a CE marked product, place an order for it together with the circuit breaker body.)

Cautions
All electrical operations are based on intermittent rating. Avoid operating any device continuously 10 times or more (ON and OFF operations are counted as one time). Operate any device at 85 to 110% of the rated operating voltage. The dielectric strength of electrical operation circuits is 1500 V. When performing dielectric strength test of any of these devices and other devices, if the test voltage exceeds the rated value (1500 V), disconnect the operation power supply terminal. When collectively operating more than one electrical operation device, isolate the devices connecting a relay to each device. If the control terminals are directly connected in parallel, a circuit will be formed, and the devices may not normally function.
Automatic reset (optional)
The automatic reset type has a built-in alarm switch in the circuit breaker and is connected in such a way that the OFF operation circuit is closed when the circuit breaker trips. Therefore, when the circuit breaker trips, it is automatically reset. However, when the circuit breaker thermally trips, it may not be automatically reset. If an automatic reset spring charge type (1) is required, the user must wire the device in accordance with the external connection diagram shown in Fig. 1 in (3).

Notes *1 For ELCB, only 3-pole circuit breakers with a frame size of 125 to 400 A can be manufactured. *2 In the case of 4-pole 125 A frame circuit breakers and U class, the circuit breakers are supplied as special models. Consult us for details. Remarks: 1. All models of the front connection type are provided with bar terminals (except the spring charge type (1)). 2. 2-pole circuit breakers of all models are obtained by removing the neutral pole conductors from 3-pole circuit breakers.
times. Then, the circuit breaker will be turned off (reset), and, at the same time, the closing spring will be charged. Although the circuit breaker can be turned off even if the switch is not turned to MANUAL, the selection switch should be set to MANUAL because remote operation may be accepted. · After turning the changeover switch to MANUAL, draw out the OFF lock plate, and lock the circuit breaker in the OFF state with padlocks (to be prepared by the user). Up to three padlocks can be fitted. f5 to f8 padlocks can be fitted. Note: After the completion of manual operation (on-site operation), return the selection switch to AUTO without fail. If it is not returned, electrical operation (remote operation) cannot be performed. Display of tripping state When the circuit breaker trips in the ON state, the tripping state is displayed. When it trips in the OFF state, the OFF state is kept displayed. Note: When it trips in the OFF state, signals from AL will not be output. Cautions for use q To the ON or OFF operation switch (to be prepared by the user), current only of 24 V DC and 15 to 30 mA flows. Use a switch for minute load. w Operate the operation switch for 0.1 s or more to turn on and for 20 ms or more to turn off. If it is operated for less than the time, it may not function. The wire to the operation switch shall be less than 100 m. e The power supply module has a built-in switching power supply. Therefore, it may interfere with communication devices near the module. In such a case, install a noise filter on the input side. r For the automatic reset type, purchase a circuit breaker with alarm switch (for minute load), and connect the signal circuit (among the terminal numbers S1, S2 and S4) as shown in Fig. 1. If the circuit breaker in the OFF state is tripped by UVT-N or the like, it cannot be automatically reset. To reset it, it is necessary to turn it on under no current. After this operation, it will be automatically reset.

q In the case of a circuit breaker with UVT, if the circuit breaker trips owing to the operation of UVT, the procedure for re-closing the circuit breaker varies depending on the condition of the electrical operation device before the circuit breaker trips. • Tripping in ON state: Reset (OFF). → Turn on. • Tripping in OFF state: Turn on (idle tripping). → Reset (OFF). → Turn on. (If the circuit breaker cannot be turned on (idle tripping), reset (OFF) it, and turn on.) • When an automatic reset system is configured on a nonreset type circuit breaker with UVT, if UVT is set to the no-voltage state, the operations to turn off (reset), trip, turn off (reset) and trip are repeated.
Therefore, configure the circuit in such a way that power is disconnected from the electrical operation device before the circuit breaker is tripped by the non-reset type UVT. w Current of about 0.2 A will flow to the ON-OFF switch. Use an appropriate switch. e Do not apply ON and OFF operation signals continuously. An interval of 0.5 sec or more is necessary between ON and OFF signals. r In the case of the automatic reset type device, it will perform the reset operation with an interval of 0.5 sec after NFB performs the tripping action. t The electrical operation device has a built-in pumping preventing circuit. Therefore, it can operate to turn off the circuit breaker while the ON operation switch is held in the closing state, but it cannot turn on continuously after turning off. To turn on, once turn off the ON operation switch, and turn on the switch. Do not apply the ON operation signal continuously. y The manual operating handle moves at a high speed during electrical operation. Pay attention to the handle. Keep the operation circuit power supply off during manual operation. u In the manual operation, surely turn the manual operating handle to the position indicated on the nameplate.

Spring charge type (2)
Electrical operation When the ON operation switch is closed, the closing coil will be excited to release the latch mechanism, and the closing spring force will instantaneously turn on the circuit breaker. When the OFF operation switch is closed, the relay will operate to start the motor, turn off (reset) the circuit breaker and, at the same time, charge the closing spring. Manual operation • Press the ON button, and the latch mechanism will be released, and the closing spring force will instantaneously turn on the circuit breaker. • Turning off (resetting) Push the leaf spring, bring out the manual handle, and move the handle upward and downward more than ten times. Then, the circuit breaker will be turned off (reset), and, at the same time, the closing spring will be charged. Cautions for use
q In Before installing or removing the electrical operation device to or from the circuit breaker, trip the circuit breaker, and discharge the electrical operation device. After the device is installed to the circuit breaker, the device will not trip the circuit breaker in the OFF state even if the trip button is pressed. This is not a trouble. The electrical operation device takes 3 seconds to turn off the circuit breaker. To open the circuit immediately by remote operation, use a circuit breaker with SHT or UVT. • The device has a built-in pumping preventing relay. w Current of about 9 A and 0.2 A will flow to the ON and OFF switches, respectively. Use appropriate switches.

8 Handling and Maintenance 1. Storage and Transportation (1) Precautions for storage Avoid corrosive gases
H 2S
Store in the OFF or tripped state
Avoid moisture
Store the breaker in the OFF state or tripped state.
Do not leave the breaker in a humid place for long periods of time.
Ammonia
Do not store the product in an atmosphere containing acidic gas or ammonia gas. H2S 0.01ppm or less SO2 0.05ppm or less NH3 0.25ppm or less
(2) Precautions for transportation Carefully pack and transport
Do not drop the package during transportation. When shipping the breaker, make sure to package it carefully.
Do not carry by holding the front and back of the flush plate
Do not carry by the lead wires
Do not carry the embedded type breaker by holding the front and back of the flush plate. The breaker could drop during transportation.
Do not carry the accessories by the lead wires. Excessive force will be applied on the accessories.
Do not transport upside down (when mounted on IEC 35mm rail)
Do not transport a panel containing parts mounted on an IEC 35mm rail in an upside down state.
2. Standard Working Conditions 䊉Working ambient temperature … -10°C to 40°C 䊉Relative humidity … 85% or less with no dew condensation. (Note that the 24-hour average value must not exceed 35°C) 䊉Altitude … 2000m or less working current reduction rate in ambient temperature exceeding 40°C. 䊉Atmosphere … Free of excessive moisture, oil vapors, 50°C… 0.9 fold smoke, dust, salt, corrosive substances, 60°C… 0.7 fold vibration or impact, etc.
Handling and Maintenance
3. Mounting and Connections
8
(1) Precautions for mounting Attention to dust and cutting chips!
Do not block ventilation ports
Make sure that the breaker does not come in contact with rain water, oil, dust or cutting chips. Special attention must be taken to conductive materials such as scraps from drilling steel plates.
Do not block the ventilation ports. The breaker performance could drop. Ensure the insulation distance for breaker mounting indicated on page 101.
Avoid direct sunlight
Make sure that the breaker is not subject to direct sunlight during use. An increase in temperature could cause malfunctions. Sunlight could also discolor the nameplate and molded case, etc.

Do not remove the rear cover from the back of the base.
Do not wipe with thinner, detergent or chemical cloth
Mounting style Pay attention to the mounting angle of the following models as the overcurrent tripping characteristics may vary according to the mounting stye. Use in a vertical direction is recommended.
Do not remove the rear cover
Do not use thinner, etc., to clean the surface of the breaker. Use compressed air or a dry cloth to clean.
8 Handling and Maintenance
(2) Precautions for Connections Oiling of threads prohibited
Connect conductors parallel to each pole
Do not apply lubricant to the threads. Oil will decrease the friction at threads and cause the screws to loosen easily, and the unit to overheat. Excessive stress will be applied on the threads even with the standard tightening torque and can cause the screws to break.
Connect each connection conductor so it is parallel to each pole.
Do not deform studs
When connecting the conductors on the rear connection type, take care not to deform the studs when tightening.
Do not connect in reverse Securely fix conductors
Electromagnetic force applied per 1m conductor (During 3-phase short-circuit)
A large electromagnetic force is applied on the connected conductor according to the accident current. Use the conditions on the right as guide and securely fix (tighten) the conductors.
Distance between conductors Current cm target value kA(Pf)
Set power to ON side ···
As a rule, do not connect the power and load in reverse. If necessary, refer to the specifications and select a model which can be connected in reverse. An insulating barrier should be provided on both the power and load sides of the breakers when using a high voltage circuit where dew condenses easily or in a circuit which has a reverse connection in the circuit.

Never connect the ELCB units in parallel as it will create a loop circuit, and could burn the magnetic device. Never connect the MCCB and ELCB in parallel.
Solderless terminal connection Untwist the connection wires, align the core wires and then tighten. The wires will loosen up during use, and must be tightened during periodic maintenance. Do not solder or bind the end of the strands. Make sure not to catch the insulating sheath of the wire when tightening.
Handling and Maintenance
When directly connecting the conductor, refer to the outline drawings and drill the conductor. When connecting the conductors to a bar terminal, pay attention to the insulating distance with the ground. A ground fault prevention barrier is available as an option.

Open and close a normally closed breaker periodically. This will clean the contact and prevent abnormal heating. Test the operation once a month.
8 Handling and Maintenance
(3) Inspection after Tripping Whether the circuit breaker can be reused or must be replaced after switching off a fault current depends on the intensity of the current which was switched off. Intensity of trip current, degree of MCCB and ELCB damage, and countermeasures Intensity of trip current
Degree of MCCB and ELCB damage
When it is clear that the circuit breaker operated
No abnormality such as contamination
within the time-delay trip range
around vent observed
(Overcurrent up to 10 times of rated current)
Countermeasures Reusable (The circuit breaker can function 50 times (100A or less) at overload current which is 6 times higher than rated current) Reusable
Soot and dust found near vent
Relatively low short-circuit current which causes instantaneous tripping Large short-circuit current close to rated breaking capacity
Soot and dust found near handle, remarkable contamination found near vent Molten metal found in circuit breaker Box of box type circuit breaker is severely deformed
Replace with a new part
If the intensity of the fault current cannot be estimated, remove the MCCB and ELCB, and measure the insulation resistance. If the specified value (5MΩ) has not been reached, perform a withstand voltage test. If the withstand voltage is within the specified value, the circuit breaker can be used temporarily but it should be replaced with a new part as soon as possible. If both the insulation resistance and withstand voltage are sufficient, the circuit breaker may be judged as reusable. However, it should be checked for abnormalities, such as an abnormal rise in temperature for a set period. 䊉 Measure the insulation resistance and perform the withstand voltage test with the procedures given in section 1 and 2 on page 238. 䊉 Check that the ELCB operates when the test button is pressed.
(4) Guide to service life Maintenance and inspection must be conducted according to the environment in which the circuit breaker is installed. The service life of the circuit breaker cannot be determined just by the number of service years.

8 Handling and Maintenance (4) Cases of unnecessary ELCB operation Even if the ELCB is not faulty, there may be a problem in the circuit which causes frequent operation or instantaneous operation at closing.

Grounding
The following five conditions are the most conceivable causes of trips in cases such as when the breaker trips immediately after the ELCB is closed, or when the breaker trips suddenly during use but inspection of circuit shows no ground fault accidents. Check each item and if any problems are found, correct them accordingly.
ig
Cause
Countermeasures
All models incorporate a non-operating shock structure and should sufficiently withstand 7kV (JIS Standards), so 1 Induction lightning unnecessary operation should not occur.
The ZCT is equipped with a magnetic shield, and is not affected easily. However, the breaker could operate if there are 2 External magnetic field
large current buses reaching several thousand amperes near the ELCB, or if there is a short-circuit fault in nearby circuit. Separate the ELCB from the large current bus wires by at least 10cm.
All models incorporate a non-operating shock structure and should not operate unnecessarily. However if there is a 3 Switching surge
time lag in the closing time of each pole in the magnetic switch, unnecessary operation could occur due to the
Handling and Maintenance
relation of the ground electrostatic capacity.
If the wires are stored in a metal conduit or metal duct wiring, the ground electrostatic capacity will increase compared to other wiring methods. This may cause the leakage current to constantly increase. If the magnetic switch chatters, etc., the leakage current may become temporarily unbalanced thus reaching a leakage current equivalent to the sensitivity current and causing unnecessary operation. 4 Effect of ground electrostatic capacity
Review the following matters in this case. 1) Shorten the load circuit line, or install the ELCB near the load (device) being used. (Install in a branch circuit.) 2) Lead the control circuit for the control device, etc., from the power on the ELCB side. 3) If the above measures are difficult or if they cause further unnecessary operation, reconsider the selected ELCB rated sensitivity current.

The ZCT is made of high-grade permalloy, a material with Ni as its main element and which has outstanding residual magnetic characteristics. The periphery of the ZCT is covered with material having outstanding magnetic characteristics, creating a complete magnetic shield. This suppresses the effect of residual currents to the 5 Equilibrium properties caused by large current at starting
minimum, and prevents the breaker from unnecessarily operating even near a current of several thousand amperes. In the relay, the characteristics change if the primary conductor is bent immediately after it is passed through the ZCT. Thus, when passing a primary conductor with current of 300A or more through the ZCT, keep the conductor straight for at least 30cm on either side.
