A I-circuit breakeriyiswitshi esinganqamula ugesi ngokuzenzakalelayo lapho isekethe ibhekene nokugcwala ngokweqile, isekethe esifushane noma ezinye izimo ezingavamile, okuvikela isekethe kanye nemishini. Ngokwendawo yokusetshenziswa, isimiso sokusebenza kanye nezinga le-voltage, ama-circuit breaker angahlukaniswa kabanzi ngezinhlobo eziningana:

Kuhlukaniswe nge-voltage yokusebenza
Ama-circuit breaker ane-voltage ephansi (LV): Asetshenziswa ezifundeni zasekhaya, zezentengiselwano kanye nezilula zezimboni, ane-voltage ejwayelekile engadluli ku-1000V. Avikela kakhulu izisekelo kanye nemishini kagesi. Izinhlobo ezivamile zifaka phakathi ama-miniature circuit breaker (MCB) kanye nama-molded case circuit breaker (MCCB).
Ama-circuit breaker ane-voltage ephezulu (HV): Asetshenziswa ezinhlelweni zezimboni, zokudlulisa amandla kanye nokusabalalisa, ngama-voltage ngokuvamile angaphezu kwe-1kV. Anganqamula imisinga emikhulu futhi avikele ukuphepha kwamagridi kagesi. Izinhlobo ezivamile zifaka phakathi ama-circuit breaker kawoyela, ama-circuit breaker ane-gas-insulated (GIS), kanye nama-circuit breaker ane-vacuum.
Hlukanisa ngendlela yokucisha i-arc
I-Air circuit breaker (ACB): Isebenzisa umoya njenge-arc-extinguishing medium futhi ifanelekela ama-voltage aphakathi naphansi.
I-Vacuum circuit breaker (VCB): Ukucima i-arc kuqedwa endaweni ye-vacuum, efanele ukusebenza ngemvamisa ephezulu futhi isikhathi eside senkonzo.
I-Oil circuit breaker (OCB): Isebenzisa uwoyela njengendlela yokucisha i-arc futhi ifanele imigqa ye-high-voltage.
I-Gas circuit breaker (SF6 CB): I-Arc extinguishing enegesi ye-sulfur hexafluoride, efanelekile ezinhlelweni ze-high-voltage kanye ne-ultra-high-voltage.
Kuhlukaniswe ngokusetshenziswa
Isivikelo sesekethe esivikelayo: Sisetshenziswa kakhulu ekuvikeleni ngokweqile kanye nokuvikela isekethe esifushane.
I-circuit breaker yohlobo lokulawula: Isetshenziselwa ukulawula ama-circuit okuvula futhi inomsebenzi wokuvikela.

Ama-circuit breaker awavikeli nje kuphela imishini yesekethe ekulimaleni, kodwa futhi aqinisekisa ukuphepha kwabasebenzi, athuthukisa ukuthembeka nokuzinza kokusebenza kwesistimu, futhi ayizingxenye ezibalulekile ezimisweni zamandla zesimanje kanye nokwenza izinto ngokuzenzakalela kwezimboni.
