主要作用
在正常情况下，过电流脱扣器的衔铁是释放着的；一旦发生严重过载或短路故障时，与主电路串联的线圈就将产生较强的电磁吸力把衔铁往下吸引而顶开锁钩，使主触点断开。欠压脱扣器的工作恰恰相反，在电压正常时，电磁吸力吸住衔铁，主触点才得以闭合。一旦电压严重下降或断电时，衔铁就被释放而使主触点断开。当电源电压恢复正常时，必须重新合闸后才能工作，实现了失压保护
工作原理
脱扣方式有热动、电磁和复式脱扣3种。
当线路发生一般性过载时，过载电流虽不能使电磁脱扣器动作，
但能使热元件产生一定热量，促使双金属片受热向上弯曲，推动杠杆使搭钩与锁扣脱开，将主触头分断，切断电源。当线路发生短路或严重过载电流时，短路电流过瞬时脱扣整定电流值，电磁脱扣器产生足够大的吸力，将衔铁吸合并撞击杠杆，使搭钩绕转轴座向上转动与锁扣脱开，锁扣在反力弹簧的作用下将三副主触头分断，切断电源。
