A Chotsegula Derandi switchgear yomwe imatha kutseka magetsi okha ngati dera likukumana ndi kuchuluka kwa magetsi, short circuit kapena zinthu zina zachilendo, kuteteza dera ndi zida. Malinga ndi malo ogwiritsira ntchito, mfundo yogwirira ntchito komanso mulingo wamagetsi, ma circuit breaker amatha kugawidwa m'mitundu ingapo:

Kugawidwa ndi mphamvu yogwira ntchito
Ma circuit breaker otsika mphamvu (LV): Amagwiritsidwa ntchito m'ma circuit apakhomo, amalonda komanso opepuka a mafakitale, okhala ndi magetsi ambiri osapitirira 1000V. Amateteza kwambiri ma circuit ndi zida zamagetsi. Mitundu yodziwika bwino ndi ma miniature circuit breaker (MCB) ndi molded case circuit breaker (MCCB).
Ma circuit breaker amphamvu kwambiri (HV): Amagwiritsidwa ntchito m'mafakitale, m'ma transmission ndi ma distribution system, ndipo ma voltage nthawi zambiri amakhala oposa 1kV. Amatha kudula ma current akuluakulu ndikuteteza chitetezo cha ma grid amagetsi. Mitundu yodziwika bwino ndi monga ma circuit breaker amafuta, ma circuit breaker otetezedwa ndi gasi (GIS), ndi ma vacuum circuit breaker.
Gawani m'magulu pogwiritsa ntchito njira yozimitsira arc
Chotsekera mpweya (ACB): Chimagwiritsa ntchito mpweya ngati chozimitsira mpweya ndipo chimagwira ntchito bwino pa ma circuits apakati ndi otsika.
Chotsekera magetsi cha Vacuum (VCB): Kuzimitsa magetsi kwa Arc kumachitika mu vacuum, yoyenera kugwiritsidwa ntchito pafupipafupi komanso nthawi yayitali.
Chotsekera magetsi cha mafuta (OCB): Chimagwiritsa ntchito mafuta ngati chozimitsira magetsi ndipo ndi choyenera kugwiritsa ntchito mawaya amphamvu kwambiri.
Chotsekera dera la gasi (SF6 CB): Chozimitsira mpweya wa Arc ndi gasi wa sulfure hexafluoride, woyenera makina amphamvu kwambiri komanso amphamvu kwambiri.
Kugawidwa m'magulu malinga ndi momwe amagwiritsidwira ntchito
Chotsekereza dera choteteza: Chimagwiritsidwa ntchito makamaka poteteza katundu wambiri komanso waufupi.
Chothyola ma circuit cha mtundu wolamulira: Chimagwiritsidwa ntchito poyang'anira ma circuit ndipo chimagwiranso ntchito yoteteza.

Zotsekereza ma circuit sizimangoteteza zida za circuit kuti zisawonongeke, komanso zimateteza chitetezo cha ogwira ntchito, zimawonjezera kudalirika ndi kukhazikika kwa magwiridwe antchito a dongosolo, ndipo ndi zinthu zofunika kwambiri pamakina amagetsi amakono komanso makina odziyimira pawokha a mafakitale.
