主要作用
在正常情況下，過電流脫扣器的銜鐵是釋放著的；一旦發(fā)生嚴重過載或短路故障時，與主電路串聯(lián)的線圈就將產(chǎn)生較強的電磁吸力把銜鐵往下吸引而頂開鎖鉤，使主觸點斷開。欠壓脫扣器的工作恰恰相反，在電壓正常時，電磁吸力吸住銜鐵，主觸點才得以閉合。一旦電壓嚴重下降或斷電時，銜鐵就被釋放而使主觸點斷開。當電源電壓恢復(fù)正常時，必須重新合閘后才能工作，實現(xiàn)了失壓保護
工作原理
脫扣方式有熱動、電磁和復(fù)式脫扣3種。
當線路發(fā)生一般性過載時，過載電流雖不能使電磁脫扣器動作，
但能使熱元件產(chǎn)生一定熱量，促使雙金屬片受熱向上彎曲，推動杠桿使搭鉤與鎖扣脫開，將主觸頭分斷，切斷電源。當線路發(fā)生短路或嚴重過載電流時，短路電流過瞬時脫扣整定電流值，電磁脫扣器產(chǎn)生足夠大的吸力，將銜鐵吸合并撞擊杠桿，使搭鉤繞轉(zhuǎn)軸座向上轉(zhuǎn)動與鎖扣脫開，鎖扣在反力彈簧的作用下將三副主觸頭分斷，切斷電源。
