Sebakeng sa litsamaiso tsa motlakase, MCCB (Molded Case Circuit Breaker) e phetha karolo ea bohlokoa ho netefatsa polokeho le ts'epahalo ea ts'ebetso eohle. Li-MCCB li etselitsoe ho sireletsa lipotoloho ho tsoa ho meroalo e mengata le lipotoloho tse khutšoane, ho li etsa karolo ea bohlokoa ts'ebetsong efe kapa efe ea motlakase.
E 'ngoe ea likarolo tsa bohlokoa tsa MCCB ke bokhoni ba eona ba ho fana ka ts'ireletso e tšepahalang ea overcurrent. Sena se finyelloa ka ts'ebeliso ea li-unit tsa maeto a thermal-magnetic, tse khonang ho lemoha lintho tse ngata haholo le li-circuits tse khutšoane. Ha overcurrent e fumanoa, MCCB e tla khoptjoa le ho sitisa phallo ea motlakase, ho thibela tšenyo leha e le efe e ka bang teng tsamaisong ea motlakase.
Ho feta moo, li-MCCB li etselitsoe ho khutlisoa habonolo kamora ho khoptjoa, ho lumella ho khutlisa matla ka potlako ntle le tlhokomelo e pharaletseng. Tšobotsi ena e bohlokoa ka ho khetheha libakeng tsa khoebo le tsa indasteri, moo ho fokotseha ho ka fellang ka tahlehelo e kholo ea lichelete.
Karolo e 'ngoe ea bohlokoa ea MCCB ke bokhoni ba eona ba ho fana ka khokahanyo e khethehileng. Sena se bolela hore ha ho ka ba le phoso, ke MCCB feela e anngoeng ke phoso e tla khoptjoa, athe tse ling tsa MCCB tse ka holimo ho noka li ke ke tsa ameha. Sena se etsa bonnete ba hore lipotoloho tse amehileng feela li arotsoe, ho fokotsa tšitiso ho tsamaiso eohle ea motlakase.
Ntle le ts'ebetso ea eona ea ts'ireletso, li-circuit breakers tse bōpiloeng li boetse li na le melemo ea sebopeho sa compact le ho kenya habonolo. Moqapi oa eona o kopanetsoeng o etsa hore e tšoanelehe bakeng sa mefuta e mengata ea likopo ho tloha mohahong oa bolulo ho ea mehahong ea indasteri.
Ka bokhutšoane, li-circuit breakers ke karolo ea bohlokoa haholo lits'ebetsong tsa motlakase, tse fanang ka ts'ireletso e ts'epahalang ea overcurrent le short-circuit. Bokhoni ba eona ba ho fana ka khokahano e ikhethileng le mesebetsi ea ho seta bocha ka potlako e etsa hore e be letlotlo la bohlokoa ho netefatsa polokeho le ts'epahalo ea lisebelisoa tsa motlakase. Ha thekenoloji e ntse e tsoela pele, karolo ea MCCB tsamaisong ea motlakase e tla ba ea bohlokoa le ho feta, kahoo ke habohlokoa hore baenjiniere le litsebi tsa motlakase ba utloisise ka botlalo bohlokoa ba bona.
