The AC contactor uses the main contact to control the circuit, and the auxiliary contact to conduct the control loop.
The main contact is generally a normally open contact, and the auxiliary contact often has two pairs of normally open contacts and a normally closed contact. Small contactors are often used as intermediate relays to cooperate with the main circuit.
The contacts of the AC contactor are made of silver-tungsten alloy, which has good electrical conductivity and high temperature ablation resistance.
The power of the AC contactor's action comes from the magnetic field generated by the AC passing through a coil with an iron core. The electromagnet core is composed of two "hill" shaped young silicon steel sheets. One of the fixed iron cores is covered with a coil. The working voltage can be varied. select. In order to stabilize the magnetic force, a short-circuit ring is added to the suction surface of the iron core. The AC contactor relies on spring to reset after power failure.
