The role of AC contactor?

One of the functions of a household AC contactor is to control a large current with a small current. The coil is energized and the iron core generates magnetic force together to attract the moving contact of the contactor. Let the larger working current be delivered to the higher-power electrical equipment, such as motors, resistance furnaces, etc., through the moving contacts.

Another function of the contactor is to effectively extinguish the arc when starting larger equipment. Prevent arc short circuit caused.

AC contactor is an automatic switch control electrical appliance, which is used for remote control in low-voltage power distribution systems, and is frequently operated in AC and DC main circuits or large-capacity control circuits.
