YUANKY MCB 1-63A 240/415V AC 1p 2p 3p 4P iec60898 BCD curve mini air circuit breaker

Tsananguro pfupi:

Mukuru

S7 ine simba guru rekudzora simba remagetsi rinoita kuti simba rekuparadzwa ridzikire nekuda kwekufamba kwenguva pfupi kuenda kumagetsi. chiyero chikuru. Kushanda: Kwekudzivirira tambo nemidziyots kurwisa overload uye short circuit.

Mitemo yakajairika yekusarudza MCB.

Ruzivo rwehunyanzvi rwe network panguva ino rwunofungwa nezvarwo:

Masisitimu evhu, magetsi mapfupi ari panzvimbo yekuisira circuit breaker. gara uri Simba remagetsi risingasviki pakutyoka kwemudziyo uyu, rinobva rava nemagetsi akajairwa enetwork.

Kune maitiro matatu ekushanda kwemagineti:

Kudzivirira nekudzora macircuit eB curve (3-5In) kubva patambo dzeTN neIT SYSTEMS.

Kudzivirira nekudzora macircuit kubva pakuwanda kwemagetsi ne ma short-circuit (C curve); dziviriro yemitoro inodzivisa uye inductive ine inrush current yakaderera.

D curve (10-20In) dziviriro uye kudzora macircuit kubva pakuwedzeredza ma short-circuit; dziviriro yematunhu anopa mitoro ine simba rakawanda rekupinda mukati pa the kuvhara kwedunhu (LV/LV) matransformer, marambi ekupwanya magetsi).
