Chii chinonzi Molded Case Circuit Breaker

Makaputsi edunhu akaumbwa(MCCB) inogona kudzima magetsi otomatiki mushure mekunge magetsi adarika mafambiro ekufamba. Molded case inoreva kushandiswa kwepurasitiki inodziisa magetsi sechikamu chekunze chemudziyo wekubvisa maconductor nezvikamu zvesimbi zviri pasi. Ma currents anowanzo shandiswa akadai se: 16, 25, 30, 40, 50, 63, 80, 100, 125, 160, 200, 225, 250, 315, 350, 400, 500, 630A.
Musimboti wekushanda:
Makontakti makuru ecircuit breaker anovharwa nemaoko kana nemagetsi. Mushure mekunge makontakti makuru avharwa, free tripping mechanism inovhara makontakti makuru munzvimbo yakavharwa. Coil yekuburitsa overcurrent nechinhu chekupisa chekuburitsa thermal zvakabatana zvakatevedzana necircuit huru, uye coil yekuburitsa undervoltage yakabatana pamwe chete nemagetsi.
Kana circuit pfupi kana overload yakanyanya ikaitika mucircuit, armature yekubuda kwe overcurrent inokwezvwa, zvichiita kuti free gripping mechanism ishande uye main contacts abvise main circuit.
Kana dunhu rakawandisa, chinhu chinodziya chekuburitsa thermal chinodziya uye chinokotamisa bimetallic strip, zvichisundira free tripping mechanism kuti ishande, uye main contact inobvisa main circuit.
Kana dunhu risina simba rakawanda, simbi yekusunungurwa kwesimba rakaderera inoburitswa, iyo inovhurawo nzira yekusundira pasina simba uye inobvisa dunhu guru.
Kana bhatani rekusunungura shunt rikadzvanywa, armature ye shunt release inokwezvwa, free tripping mechanism inovhurwa, uye main contact inobvisa main circuit.
