Tips: Functions of AC magnetic contactors

The carrying current of the AC contactor is very large. Generally, whether the internal pull-in coil controls its action or not, and the control coil is operated by various types of relays connected in series with it. After a lightning strike, it will trip because the relay of the contactor has an overcurrent or grounding protection function. When there is lightning on the line, it will control the action of the AC contactor and cut off the load power to protect the equipment from high voltage, high current damage or grounding safety hazards.

AC contactor is an automatic control electrical appliance. The electrical contactor is mainly used to frequently switch on or disconnect AC and DC circuits. It has a large control capacity and can be operated remotely. It can be used with relays to achieve timing operation, interlock control, various quantitative controls, and loss of voltage and undervoltage protection. It is widely used in the automatic control circuit, the main control object is the motor, and it can also be used to control other electrical loads, such as electric heaters, lighting, electric welding machines and capacitor banks, etc.
