在电工学上，因为接触器是一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。接触器控制容量大，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。HMCP250K5CU18

断路器(英文名称:circuit-breaker，circuit breaker)是指能够关合、承载和开断正常回路条件下的电流并能关合、在规定的时间内承载和开断异常回路条件下的电流的开关装置。断路器按其使用范围分为高压断路器与低压断路器，高低压界线划分比较模糊，一般将3kV以上的称为高压电器。HMCP400X5A01

接触器选择口诀接触器辅助常开触点与启动按钮并联，其并联后的组合体串联在停止按钮与接触器线圈之间。1、3、5接三相电源，（主电路部分）2、4、6接三相电机A1、A2是这个接触器的线圈，接到控制电路里面去，通过控制这个接触器的线圈（A1、A2）来实现控制住电路部分的电机（以小控大）。
