Primary incoming of low voltage Withdrawable switchgear is connected by primary connector, after current coming, it passes through the primary line to the air circuit breaker,and then air circuit breaker reaches the contactor through the wire, and after the contactor comes out, it reaches the output plug-in through CT to connect with the external.
At the same time, the motor integrated protector works with CT to detect current and voltage. In case of abnormal situations such as too long start up time, blocked rotation, over current, over load, low voltage, phase loss and three-phase imbalance in operation, it will direct the contactor and air switch trip to protect the motor and circuit.
