China MCB FTCQP 1 Pole 20A TPN MCB Iyo 50Hz Electrical Miniature Circuit Breaker fekitori nevagadziri

MCB FTCQP 1 Pole 20A TPN MCB 50Hz Electrical Miniature Circuit Breaker Mufananidzo Wakaratidzwa

MCB FTCQP 1 Pole 20A TPN MCB Iyo 50Hz Electrical Miniature Circuit Breaker

Tsananguro pfupi:

1. Kushandiswa: Kudzivirira tambo nemidziyo kubva pakuzara kwemagetsi uye kupfupika kwemagetsi.

2. Mitemo mikuru yekusarudza MCB.

a. Ruzivo rwehunyanzvi rwenetwork panzvimbo inofungwa nezvayo: Masisitimu earthing, short-circuit current panzvimbo inoiswa circuit breaker, iyo inofanira kugara iri pasi pesimba rekutyora remudziyo uyu, network normal voltage.

b. Kune hunhu hutatu hwemakove ekushanda kwemagineti: B curve (3-5 In) kuchengetedza uye kudzora maseketi kubva patambo dzehurefu muTN uye IT systems.

c. curve (5-10 In) kudzivirira nekudzora macircuit kubva pakuwanda kwemagetsi uye ma short-circuit; dziviriro ye resistive uye inductive loads ine inrush current yakaderera.

Dcurve (10-20 In) kudzivirira nekudzora macircuit kubva pakuwanda kwemagetsi uye ma short-circuit; dziviriro kumacircuit anopa mitoro ine inrush current yakakwira pakuvhara macircuit (LV/LV transformers, marambi e breakdown).
