I-circuit breaker isho idivayisi eshintshayo engavala, ithwale, futhi inqamuke ngaphansi kwezimo zesekhethi evamile futhi engavala, ithwale, futhi inqamuke ngaphansi kwezimo zesekhethi ezingavamile ngesikhathi esithile. Ingasetshenziswa ukusabalalisa amandla kagesi njalo. Iqala i-asynchronous motor futhi ivikele ulayini wamandla kanye ne-motor. Ingakwazi ukusika isekethe ngokuzenzakalelayo lapho ukulayisha ngokweqile, i-short circuit, undervoltage kanye namanye amaphutha kwenzeka. Umsebenzi wayo ulingana nenhlanganisela ye-fuse switch kanye nokushisa ngokweqile kanye ne-underheating relay, njll., futhi Ngokuvamile asikho isidingo sokushintsha izingxenye ngemva kokuphula iphutha lamanje. Isetshenziswe kabanzi.
