What is the function of AC contactor? I firmly believe that most of us don't know how to answer this question. Some people even haven't heard the proper term "AC contactor". After all, most people did not touch the industry, of course, not interested in understanding, but the AC contactor is really closely related to household electricity.

Generally speaking, the function of AC contactor is to maintain the power circuit and allow a very large amount of current. The automobile relay of AC contactor has the function of over-current or protective grounding. When there is a lightning strike on the line after the lightning strike, it will disconnect the load switching power supply to maintain the power supply circuit. It is because of this that we often encounter the situation of power cut in thunder days.

AC contactor is an automatic control household appliance. The key control target of AC contactor is motor, which is also widely used to control other power engineering loads, such as DC welding machine, power capacitor, electric water heater, lighting group, etc.

Contactor is an inductive control switch. It is used to start the motor frequently and control for a long distance, which makes the operation more safe and convenient. Contactor is one of the key low-voltage electrical equipment. Contactor is operated by magnetic field force. According to different switching power supply, it can be divided into DC and AC. The structures of the two classes are basically the same.
