Kwintsimi yeenkqubo zombane, i-MCCB (i-Molded Case Circuit Breaker) idlala indima ebalulekileyo ekuqinisekiseni ukhuseleko kunye nokuthembeka kofakelo lonke. Ii-MCCBs zenzelwe ukukhusela iisekethe ekugqithiseni kunye neesekethe ezimfutshane, zibenza zibe yinxalenye ebalulekileyo kulo nakuphi na ukufakelwa kombane.
Enye yezinto eziphambili ze-MCCB kukukwazi ukubonelela ngokhuseleko oluthembekileyo olugqithisiweyo. Oku kuphunyezwa ngokusetyenziswa kweeyunithi zohambo lwe-thermal-magnetic, ezinokubona ukugcwala kunye neesekethe ezimfutshane. Xa i-overcurrent ifunyenwe, i-MCCB iya kukhubeka kwaye iphazamise ukuhamba kombane, ukuthintela nawuphi na umonakalo onokuthi ubekho kwinkqubo yombane.
Ukongeza, ii-MCCBs zenzelwe ukusetwa kwakhona ngokulula emva kokukhubeka, ukuvumela ukubuyiselwa ngokukhawuleza kwamandla ngaphandle kokugcinwa okubanzi. Olu phawu lubaluleke kakhulu kwiindawo zorhwebo kunye nezoshishino, apho ixesha lokuphumla lingabangela ilahleko enkulu yemali.
Enye inkalo ebalulekileyo ye-MCCB kukukwazi ukubonelela ngolungelelwaniso olukhethiweyo. Oku kuthetha ukuba xa kukho impazamo, kuphela i-MCCB echaphazelekayo ngokuthe ngqo yimpazamo iya kuhamba, ngelixa ezinye ii-MCCB ezinyukayo aziyi kuchaphazeleka. Oku kuqinisekisa ukuba kuphela iisekethe ezichaphazelekayo zodwa, ukunciphisa ukuphazamiseka kuyo yonke inkqubo yombane.
Ukongeza kumsebenzi wayo wokukhusela, i-molded case circuit breakers nazo zineenzuzo zesakhiwo esincinci kunye nokufakwa lula. Uyilo lwayo oludibeneyo luyenza ilungele uluhlu olubanzi lwezicelo ukusuka kulwakhiwo lweendawo zokuhlala ukuya kwiindawo zoshishino.
Ngamafutshane, ii-breakers zesekethe ezibunjiweyo ziyinxalenye eyimfuneko kwiinkqubo zombane, zibonelela ngokhuseleko oluthembekileyo lwe-overcurrent kunye ne-short-circuit. Ikhono layo lokubonelela ngolungelelwaniso olukhethiweyo kunye nemisebenzi yokusetha kwakhona ngokukhawuleza yenza ukuba ibe yimpahla ebalulekileyo ekuqinisekiseni ukhuseleko kunye nokuthembeka kofakelo lombane. Njengoko iteknoloji iqhubela phambili, indima ye-MCCBs kwiinkqubo zombane iya kuba yinto ebaluleke kakhulu, ngoko ke kubalulekile ukuba iinjineli kunye neengcali zombane ziqonde ngokupheleleyo ukubaluleka kwazo.
