Article Introduction：AC contactor is a low-voltage control appliance widely used in power control systems. It is mainly used to control the operation of motors and equipment. Its structure consists of moving and static contacts, arc extinguishing device, electromagnetic coil, etc. When the coil is energized, the electromagnetic force attracts the moving contact and the static contact to connect, and the circuit is connected; after the power is turned off, the moving contact is released, the contacts separate, and the circuit is disconnected. AC contactors carry large currents, and their actions are usually controlled by relays. It has a wide range of applications, such as starting equipment, forward and reverse control, remote control, protection of motor overload and phase loss, etc., and is widely used in electric drive and automatic control systems.
