Mumunda wemagetsi masisitimu, MCCB (Molded Case Circuit Breaker) inoita basa rakakosha mukuona kuchengetedzwa uye kuvimbika kwekuiswa kwese. MCCBs dzakagadzirirwa kuchengetedza maseketi kubva pakuremerwa uye mapfupi maseketi, achiaita chinhu chakakosha mune chero kuiswa kwemagetsi.
Chimwe chezvinhu zvakakosha zveMCCB kugona kwayo kupa yakavimbika overcurrent dziviriro. Izvi zvinowanikwa kuburikidza nekushandiswa kweiyo thermal-magnetic trip units, iyo inogona kuona yakawandisa uye mapfupi maseketi. Kana overcurrent yaonekwa, MCCB inogumbura uye kukanganisa kuyerera kwemagetsi, kudzivirira chero kukuvara kunogona kuitika kumagetsi.
Pamusoro pezvo, maMCCB akagadzirwa kuti agadziriswe nyore nyore mushure mekutsika, achibvumira kukurumidza kudzoreredza kwesimba pasina gadziriso yakakura. Ichi chimiro chinonyanya kukosha munzvimbo dzekutengeserana uye dzemaindasitiri, uko kuderera kunogona kukonzera kurasikirwa kukuru kwemari.
Chimwe chinhu chakakosha cheMCCB kugona kwayo kupa kurongeka kwakasarudzika. Izvi zvinoreva kuti kana pakaitika chikanganiso, MCCB chete inobatwa zvakananga nemhosva ndiyo inogumburwa, nepo mamwe maMCCB ari kumusoro kwerwizi haazokanganisike. Izvi zvinovimbisa kuti chete matunhu akabatwa ari ega, achideredza kukanganisa kune mamwe ese emagetsi system.
Pamusoro pebasa rayo rekudzivirira, akaumbwa kesi edunhu mabreaker anewo zvakanakira compact chimiro uye nyore kuisirwa. Iyo compact dhizaini inoita kuti ive yakakodzera kune dzakasiyana siyana dzekushandisa kubva pakuvaka kwekugara kusvika kune maindasitiri.
Muchidimbu, akaumbwa nyaya dzedunhu mabreaker chinhu chakakosha mumagetsi masisitimu, achipa yakavimbika overcurrent uye pfupi-circuit kuchengetedzwa. Kugona kwayo kupa yakasarudzika kurongeka uye nekukurumidza kuseta mabasa kunoita kuti ive chinhu chakakosha mukuchengetedza kuchengetedzwa uye kuvimbika kwekuiswa kwemagetsi. Sezvo tekinoroji ichienderera mberi, basa reMCCBs mumasisitimu emagetsi rinotonyanya kukosha, saka zvakakosha kuti mainjiniya nevemagetsi vanzwisise zvizere kukosha kwavo.
