In electrical engineering, because the contactor is a device that can quickly cut off the AC and DC main circuit and can frequently turn on and off the large current control (up to 800A) circuit, it is often used in motors.
As a control object, it can also be used to control the power load of factory equipment, electric heaters, working machines and various power units, and the contactor can not only switch on and off the circuit, but also has a low voltage release protection effect. Contactor control capacity is large, suitable for frequent operation and remote control, is one of the important components in automatic control system.

Contactor as a high-power switching device, widely used in aerospace, aviation, weapons, ships, electronics and other systems and equipment, its control of the load current is greater than 25A, the voltage is 25VDC:
115VAC, 402Hz; 386VAC, 50Hz, in the equipment is mainly used as a distribution switch for power control or control of high-power motor start-stop control, etc., is a key device in the equipment, plays an important role. In industrial electricity, there are many models of contactors, and the working current varies from 5A-1000A, which is quite useful.

The working principle of the contactor is as follows: when the contactor coil is energized, the coil current will generate a magnetic field, the magnetic field generated makes the static iron core produce electromagnetic suction to draw the | moving iron core, and drives the AC contactor point action, normally closed contact is disconnected, normally open contact is closed, the two are linked. When the coil is powered off, the electromagnetic suction disappears, and the armature is released under the action of the release spring, so that the contact is restored, the normally open contact is disconnected, and the normally closed contact is closed. The working principle of a DC contactor is somewhat similar to that of a temperature switch.
