[ Appearance and Operation Method ]
Caution) In case of manual operation, if one source
Ex) A Source --> Transfer B Source
put in on, the ATB must be tripped before input the other source to avoid the electrical accident & clash.
- A(On) --> A(Off) --> B(On)
B Source --> Transfer A Source -
B(On) --> B(Off) --> A(On)
Appearance & Operation Method Manual Operation Method After input charging spring using handle, if input button (On) push, it throws in. If trip button (Off) push, it trips. • When input charging completely, the charging display shows “CHARGE” • The Input and the Trip button is not working simultaneously because of mechanical interlock system. • The condition of main contact of ATB, Close or Open, is represented on State Display. • In order to keep the right position of Handles, the both sources should be charged completely.
Motor charging operation • Input spring charge automatically by electric motor. After charging, charging display shows “CHRAGE” • When Input button push (On) manually, it throws in showing “DISCHARGE” on Charging Display and “Close” on State Display. • At this time, Input spring charge automatically by electric motor. After charging, charging display shows “CHRAGE” • When Trip button push (Off) manually, it trips showing “OPEN” on State Display. • At this time, the spring charge automatically by electric motor. After charging, charging display shows “CHRAGE” • The Both sources are not working simultaneously because of mechanical interlock system. • When both sources OPEN position, the both sources should be shutted off.

[ Special Function of ATB ] Generally, the Circuit Breakers should be designed and installed at the front and rear of ATS in order to protect the electric equipment from fault current, such as ground fault, short circuit and surge. When fault and abnormal current occurs, ATB must designed and produced in order to stand at least 20 times of rated current and 3 cycles before trip.
