Tips: Electromagnetic system of AC contactor
The electromagnetic system of the AC contactor is mainly composed of three parts: coil, iron core and armature. Its function is to make the armature and the iron core pull in or release by energizing or de-energizing the electromagnetic coil, thereby driving the moving contact and the static contact to close or break to realize the purpose of connecting or breaking the circuit.
50A 4 pole normally open mechanical interlocking AC contactor is a combination of two reversing contactor and a mechanical interlock, which meets IEC standard, auxiliary contact 2NC, coil rated voltage from 24V AC, 36V, 48V to 380V.
