A Muputsi wedunhuiswitchgear inogona kudzima magetsi otomatiki kana dunhu rikasangana nekuwanda kwemagetsi, short circuit kana mamwe mamiriro asina kujairika, zvichidzivirira dunhu nemidziyo. Zvichienderana nenzvimbo yekushandisa, musimboti wekushanda uye voltage level, macircuit breaker anogona kupatsanurwa mumhando dzakasiyana-siyana:

Yakarongwa nemagetsi anoshanda
Ma "low-voltage circuit breakers" (LV): Anoshandiswa mu "household, business and easy industrial circuit circuit circuit circuit circuit breakers", ane "general voltage" isingapfuure 1000V. Anonyanya kuchengetedza ma "circuit circuit breakers" ne "molded case circuit breakers". Mhando dzakajairika dzinosanganisira ma "miniature circuit breakers" (MCB) uye "molded case circuit breakers" (MCCB).
Ma "high-voltage circuit breakers" (HV): Anoshandiswa mumaindasitiri, mu "power transmission" uye mu "distribution systems", ane ma "voltage" anopfuura 1kV. Anogona kudimbura ma "currents" makuru uye kuchengetedza kuchengetedzeka kwema "power grids". Mhando dzakajairika dzinosanganisira ma "oil circuit breakers", ma "gas-insulated circuit breakers" (GIS), uye ma "vacuum circuit breakers".
Sarudza nenzira yekudzima arc
Chinopwanya mhepo (ACB): Chinoshandisa mhepo senzira yekudzima mhepo uye chakakodzera macircuit emagetsi ari pakati nepakati neakaderera.
Muchina wekudzima dunhu reVacuum (VCB): Kudzima gomba reArc kunopedzwa munzvimbo ine vacuum, yakakodzera kushandiswa nefrequency yakawanda uye kwenguva refu.
Chinopwanya dunhu remafuta (OCB): Chinoshandisa mafuta senzira yekudzima magetsi uye chakakodzera mitsetse ine simba guru.
Gas circuit breaker (SF6 CB): Arc extinguisher ine sarufa hexafluoride gas, yakakodzera masisitimu ane voltage yakawanda uye ultra-high-voltage systems.
Yakarongwa nekushandiswa
Chinodzivirira circuit breaker: Chinonyanya kushandiswa kudzivirira overload uye short-circuit.
Chinopwanya dunhu remhando yekudzora: Chinoshandiswa pakudzora dunhu rinodzima magetsi uye chine basa rekudzivirira.

Macircuit breaker haangodziviriri michina yecircuit kubva mukukuvadzwa chete, asiwo anovimbisa kuchengetedzeka kwevashandi, anowedzera kuvimbika uye kugadzikana kwekushanda kwesystem, uye zvinhu zvakakosha mumagetsi emazuva ano uye otomatiki yeindasitiri.
