Miniature Circuit Breaker (MCB) ke mofuta oa sekhahla sa potoloho se nyane ka boholo.Hang-hang e khaola potoloho ea motlakase nakong ea boemo leha e le bofe bo sa pheleng tsamaisong ea phepelo ea motlakase, joalo ka tefiso e feteletseng kapa motlakase o mokhuts'oane.Leha mosebelisi a ka seta MCB bocha, fuse e ka bona maemo ana, mme mosebelisi o tlameha ho e nkela sebaka.
MCB ke sesebelisoa sa motlakase se sireletsang lithapo tsa motlakase le meroalo ho tsoa ho inrush current, ho thibela mello le likotsi tse ling tsa motlakase.MCB e bolokehile ho sebetsa, 'me e khutlisa matla ka potlako.Bakeng sa ts'ireletso ea potoloho e fetelletseng le ea nakoana lits'ebetsong tsa bolulo, MCB ke khetho e tsebahalang haholo.Li-MCB li potlakile haholo ho seta bocha 'me ha li hloke tlhokomelo.Maikutlo a tlatsetso a bi-metal a sebelisoa ho li-MCBs ho itšireletsa khahlanong le ho phalla ha hona joale le nako e khuts'oane ea potoloho.
