AC contactor plays the role of switching on or off the power switch in the circuit. Its working principle is similar to that of AC relay, but the quantity structure, application occasions and installation methods of Electromagnetic switch zd are different. AC contact circuit is often used in electrical circuits where the rated load current is greater than 10A and the starting current is more than 60A. The rated working voltage of the control coil of the AC contactor used in the electrical system of the central air conditioner is generally 220V, connect the coil current circuit in the way of connecting with the relay contact, and control the on-off of the circuit power supply by connecting or disconnecting the contact, achieve the purpose of controlling the load of high-power electrical appliances.
