3 pole 3 phase AC magnetic contactor with 24V/110V/220V coils is a form of electrical relay found on electric motors. It is used for long distance breaking circuit and frequently starting or controlling motors.
Tips: Why do you need to buy an ATO AC magnetic contactor?
The AC magnetic contactor is generally used to start and control equipment. It uses different control wiring methods to control the forward and reverse rotation, start and stop of the electrical motor, and can realize remote control by controlling the length of the cable. Changing the connection can also realize multiple controls. In the state of power failure, the motor can be stopped to prevent it from running due to the power on again, which will protect the operators from unforeseen injuries. Of course, the motor can be started manually after the power goes on again. The AC contactor can be used together with an overheating relay or a motor protector to achieve the purpose of protecting the motor.
