Molded Case Circuit Breaker (MCCB)chikamu chakakosha chehurongwa hwekugovera magetsi. Yakagadzirirwa kuchengetedza kuiswa kwemagetsi nevashandi kubva kunjodzi dzinogona kukonzerwa nekushomeka kwemasekitori, kuwanda kwemagetsi nezvimwe zvikanganiso zvemagetsi. Nekuda kwekuvimbika kwayo uye kushanda kwayo,MCCBinowanzoshandiswa muzvivakwa zvemabhizinesi, zvemaindasitiri, uye zvekugara.
Chimwe chezvakanakira zvikuru zveMCCBkugona kwayo kumisa kufamba kwemagetsi panguva yekukanganisa. Kana paine short circuit kana overload,MCCBInokurumidza kuona kuyerera kwemagetsi kusina kujairika uye inovhura nzvimbo dzayo, ichibvisa dunhu risina kunaka kubva pane zvimwe zviri kuiswa. Mhinduro iyi inokurumidza inobatsira kudzivirira kupisa zvakanyanya uye moto unogona kuitika, zvichiita kuti chivako nevanogaramo vagare vakachengeteka.
MCCBsanozivikanwawo nekuvakwa kwawo kwakasimba, izvo zvinoita kuti akwanise kutsungirira mafungu emvura akakwira. Aya macircuit breaker anowanzo gadzirwa nezvinhu zvinogara kwenguva refu, zvakaita sedzimba dzakaumbwa, uye akagadzirwa kuti akwanise kutakura mhando dzakasiyana dzemagetsi. Anogona kutsungirira mafungu emhepo akakwira uye anopa dziviriro yakavimbika kunyangwe munzvimbo dzakaoma dzemagetsi.
Pamusoro pezvo,MCCBine zvimwe zvinhu zvekuwedzera mashandiro ayo uye kuchinjika kwayo.MCCBszvinosanganisira marongero erwendo anogadziriswa, zvichibvumira mushandisi kugadzirisa mhinduro yecircuit breaker kune mamwe magetsi. Ichi chinhu chinobatsira zvikuru mumashandisirwo anoda mazinga akasiyana emagetsi, senge munzvimbo dzemaindasitiri dzine michina yakasiyana.
Pamusoro pezvo,MCCBskazhinji kacho dzine nzira dzekudzivirira dzakavakirwa mukati dzakadai sekupisa nemagnetic tripping. Chinodzivira kupisa chinodzivirira kubva pakuwanda kwemagetsi nekuona kupisa kwakanyanya, nepo chinodzivira magnetic tripper chinopindura kupfupi kwemagetsi nekuona kuwedzera kamwe kamwe kwemagetsi. Dziviriro iyi yakawanda inoita kuti MCCB iite nekukurumidza kune zvikanganiso zvakasiyana-siyana zvemagetsi, zvichideredza kukuvara uye nguva yekumira kushanda.
Muchidimbu,macircuit breakers ekesi akaumbwazvinhu zvakakosha muhurongwa hwekugovera magetsi. Kugona kwayo kuona nekuita zvinoenderana nemamiriro ezvinhu asina kujairika, pamwe chete nekuvakwa kwayo kwenguva refu nezvimwe zvinhu, kunoita kuti ive chishandiso chakakosha chekuona kuchengetedzeka kwemagetsi mumabasa akasiyana-siyana. Ingave muzvivakwa zvemabhizinesi, zvemaindasitiri kana zvekugara,MCCBsinopa dziviriro yakavimbika uye inoshanda yekudzivirira matambudziko emagetsi kuchengetedza michina nevashandi.
