Vacuum contactor is a kind of on-off switch used in AC power supply environment, which is widely used in various control circuits at present. It is energized through the coil to control the closing of the normally open contact and the opening of the normally closed contact. When the coil is de-energized, the normally open contact is reset and disconnected, and the normally closed contact is reset and closed. ATO has 3 phase, 4 pole vacuum AC contactors for sale online.
