接触器是—种可快速切断交流与直流主回路且可频繁地接通与关断大电流控制(达800A)电路的装置，所以经常运用于电动机作为控制对象，也可用作控制工厂设备、电热器工作母机和各样电力机组等电力负载，接触器不仅能接通和切断电路，而且还具有低电压释放保护作用。

接触器控制容大，适用于频繁操作和远距离控制，是自动控制系统中的重要元件之一。接触器作为—个大功率开关器件，广泛应用于航天、航空、兵器.船舶、电子等系统装备中，其控制的负载电流大于25A电压25VDC;115VAC、402Hz;386VAC、50Hz,在装备中主要作为配电开关进行电源控制或者控制大功率电机的启停控制等是装备中的-个关键器件,起着重要的作用。

在工业电气中,接触器的型号很多，工作电流在5A-1000A的不等，其期处相当广泛。交流接触器利用主接点来控制电路，用辅助接点来导通控制回路。

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, so it is often used in the motor as a control object, but also can be used to control factory equipment, electric heater working machine and various power units and other power loads, contactor can not only turn on and off the circuit, It also has low voltage release protection.

Contactor control capacity is large, suitable for frequent operation and remote control, is one of the important components in automatic control system. As a high-power switching device, contactor is widely used in aerospace, aviation and weapons. In Marine, electronic and other system equipment, the load current controlled by it is greater than 25A voltage 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, and its period is quite wide. The AC contactor uses the main contact to control the circuit and the auxiliary contact to conduct the control loop.
