Magnetic AC reversing contactor with a mechanical interlock can save electric energy and eliminate power frequency noise. It is a mechanical system that has simple structure and easy mounting to control circuit.

Tips: Auxiliary contact of AC contactor

Auxiliary contacts can be divided into normally open point NO and normally closed point NC. Normally open point NO is mainly used for contactor self-locking control and transmission of operating signals, for example: AC contactor normally open point NO connected to a red indicator light can be used as the running indicator light of the motor, when the AC contactor is energized, The normally open point NO is closed, and the indicator light is turned on to transmit the operating signal of the motor or circuit. The normally closed point NC of the AC contactor. The normally closed point NC of the AC contactor is mainly used for circuit interlocking and signal transmission. For example: The interlock function of the NC of the contactor's normally closed point is used in the motor forward and reverse control circuit. The normally closed point NC of the AC contactor is connected to a green indicator light, which can be used as a stop indicator for the circuit or motor. When the AC contactor is energized, the normally closed point NC is disconnected, the stop indicator light is off, and the corresponding running indicator light is on, and the circuit run.
