The role of the contactor

Update:18-11-2020

The contactor is an automatic electromagnetic type electric appliance, which is suitable for frequently connecting and disconnecting AC and DC main circuits and large-capacity control circuits over long distances. It is mainly used in automatic control of AC and DC motors, electric heating equipment, capacitor banks, resistance furnaces, etc.

It can not only reduce the labor intensity of the operator, make the operator avoid high-voltage, high-current circuits to ensure personal safety, but also control the capacity can be large, reliable operation, high operating frequency, long service life, and low voltage ( Under-voltage and voltage-loss) release protection functions are widely used.
