● Ngaphansi kwezimo ezivamile, i-circuit breaker ingasetshenziswa njengomugqa wokusabalalisa amandla kanye nokuvikela ukugcwala ngokweqile, i-short circuit kanye ne-undervoltage yomugqa kanye nemishini yamandla.
● Ama-circuit breaker okuvikela ama-motor, asetshenziswa kumanethiwekhi okusabalalisa ukuphula ama-motor e-squirrel-cage ngesikhathi sokuqala nokusebenza kanye nokuvikela ama-motor e-squirel-cage ekucindezelweni ngokweqile, i-short circuit kanye ne-undervoltage.
● Ama-circuit breaker angafakwa ngokumanoma ngokuvundlile.

● Izinga lokungcola: izinga 3;
● Isigaba sokufakwa: Ⅱ;
● Insimu yamagnetic yendawo yokufaka akufanele idlule izikhathi ezi-5 zensimu yamagnetic kunoma iyiphi indlela;
● Endaweni engeyona ingozi yokuqhuma, futhi lapho kungekho khona igesi noma uthuli oluhambisa umoya olwanele ukugqwala insimbi nokubhubhisa ukufudumala;
● Akukho ukuguguleka okuvela emoyeni naseqhweni;
● Ingafakwa ngokuvundlile nangokuqondile;
● Akufanele kube khona umthelela omkhulu nokudlidliza endaweni yokufakwa, futhi akufanele kufakwe ezindaweni ezivuthayo neziqhumayo.
