What are AC contactors used for? How are they classified?

Contactors are divided into AC contactors (voltage AC) and DC contactors (voltage DC), which are used in electric power, power distribution and power consumption occasions. In a broad sense, contactors refer to the use of coils flowing through currents in industrial electricity to generate magnetic fields, so that The contact is closed to control the load of the electrical appliance. Next, let's take a look at the classification method of AC contactors and some related knowledge.
