I-MCCB Molded case circuit breaker

Oxhumana naye oyinhlokoi-circuit breaker ene-voltage ephansiivaliwe ngesandla noma ngogesi. Ngemva kokuba othintana naye omkhulu evaliwe, indlela yokukhubeka ekhululekile ivala othintana naye omkhulu endaweni evaliwe. Ikhoyili ye-ngaphezu kokukhishwa kwamanjekanye nesici sokushisa sokukhululwa kokushisa kuxhunywe ngokulandelana nesekethe eyinhloko, kanye nekhoyili yeukukhululwa kwe-undervoltageixhunywe ngokuhambisana nokunikezwa kwamandla.
Uma isekethe ifinyeziwe noma igcwele kakhulu, i-armature ye-ukukhishwa kwamanje ngokweqileizongena ukuze yenze indlela yokukhubeka yamahhala isebenze, futhi ukuxhumana okuyinhloko kuzonqamula isekethe eyinhloko.
Uma isekethe igcwele ngokweqile, isici sokushisa se-thermal tripper sizogoba ishidi le-bimetal, sicindezele indlela yokugoba yamahhala ukuthi isebenze, futhi ukuxhumana okuyinhloko kuzonqamula isekethe eyinhloko.
Uma iseketheukungabi namandla kagesi, i-armature yeukukhululwa kwe-undervoltageiyakhishwa, okwenza futhi indlela yokukhubeka yamahhala isebenze, futhi ukuthintana okuyinhloko kunqamula isekethe eyinhloko.
Uma inkinobho yokukhulula i-shunt icindezelwa, i-armature ye-ukukhululwa kwe-shuntiyakhangwa, okwenza indlela yokukhubeka yamahhala isebenze, futhi ukuxhumana okuyinhloko kunqamula isekethe eyinhloko
