MCCB Molded case circuit breaker

Kubatana kukuru kwemuputsi wedunhu une voltage yakadererayakavharwa nemaoko kana nemagetsi. Mushure mekunge chinhu chikuru chavharwa, nzira yekugumburwa inovhara chinhu chikuru panzvimbo yakavharwa. Koiri yepamusoro pekuburitswa kwazvinouye chinhu chinodziya chekusunungurwa kwekupisa zvakabatana zvakatevedzana nedunhu guru, uye coil yekusunungurwa kwe undervoltageyakabatana pamwe chete nemagetsi.
Kana dunhu rapfupika kana kuti rakanyanya kuwanda, armature yekuburitswa kwepanguva inoichadhonza kuti iite kuti nzira yekugumburwa ishande, uye chinobata chikuru chichabvisa dunhu guru.
Kana dunhu rakawandisa, chinhu chinodziya che thermal tripper chinokotamisa pepa re bimetal, chosundidzira free tripping mechanism kuti ishande, uye main contact ichabvisa main circuit.
Kana dunhu ririkusashanda nesimba, nhumbi dzekusunungurwa kwe undervoltageinoburitswa, izvo zvinoitawo kuti nzira yekugumburwa netambo ishande, uye kubatana kukuru kunobvisa dunhu guru.
Kana bhatani rekusunungura shunt rakadzvanywa, armature yekusunungurwa kweshuntinokwezvwa, zvichiita kuti nzira yekugumburwa ishande, uye kubatana kukuru kunobvisa dunhu guru
