Yintoni iMolded Case Circuit Breaker

Abaphuli beesekethe zetyala elibunjiweyo(I-MCCB() ingawunqumla ngokuzenzekelayo umbane emva kokuba umbane udlule ucwangciso lohambo. Ityala elibunjiweyo libhekisa ekusetyenzisweni kwee-insulators zeplastiki njengeqokobhe langaphandle lesixhobo ukwahlula ii-conductors kunye neendawo zesinyithi ezisekelwe phantsi. Ii-currents ezilinganiselweyo ezisetyenziswa rhoqo zezi zilandelayo: 16, 25, 30, 40, 50, 63, 80, 100, 125, 160, 200, 225, 250, 315, 350, 400, 500, 630A.
Umgaqo wokusebenza:
Ii-contact eziphambili ze-circuit breaker zivalwa ngesandla okanye ngombane. Emva kokuba ii-contact eziphambili zivaliwe, i-free tripping mechanism ivala ii-contact eziphambili kwindawo evaliweyo. I-coil yokukhululwa kwe-overcurrent kunye ne-thermal element yokukhululwa kwe-thermal ziqhagamshelwe ngokulandelelana kwi-circuit ephambili, kwaye i-coil yokukhululwa kwe-undervoltage iqhagamshelwe ngaxeshanye nombane.
Xa kwenzeka i-short circuit okanye i-overload enzima kwi-circuit, i-armature ye-overcurrent release iyatsalwa, nto leyo ebangela ukuba i-free tripping mechanism isebenze kwaye oonxibelelwano abaphambili baqhawule i-main circuit.
Xa isekethe igcwele kakhulu, i-thermal element yokukhululwa kwe-thermal iyatshisa kwaye igobe i-bimetallic strip, ityhala indlela yokukhubeka ekhululekileyo ukuba isebenze, kwaye i-main contact iqhawula isekethe ephambili.
Xa isekethe ingaphantsi kwamandla ombane, i-armature yokukhululwa kwe-undervoltage iyakhululwa, nto leyo ekwavuselela indlela yokugoba ekhululekileyo kwaye ikhuphe isekethe ephambili.
Xa iqhosha lokukhulula i-shunt licinezelwe, i-armature ye-shunt release iyatsalwa, indlela yokukhubeka ekhululekileyo iyavulwa, kwaye uqhagamshelwano oluphambili luqhawula isekethe ephambili.
