CJB1 18mm Width 1p+N Plug in Circuit Breaker 6ka Single Phase Featured Image

CJB1 18mm Kufara 1p+N Plug in Circuit Breaker 6ka Chikamu Chimwechete

Tsanangudzo Pfupi:

1. Kushandisa: Yekudzivirira tambo nemidziyo kubva pakuremerwa uye pfupi dunhu.

2. Mitemo yakajairika yekusarudza MCB.

2.1 Tekinoroji data yetiweki panguva yakatariswa:

Masisitimu epasi, mapfupi-sekete ikozvino panzvimbo yekumisa yedunhu, iyo inofanirwa kugara iri shoma pane yekutyora kwechigadzirwa ichi, network yakajairika voltage.

2.2 Pane 3 curve maitiro ekuita magineti:

B curve (3-5 In) kuchengetedza uye kutonga kwemaseketi kubva kureba tambo muTN uye IT masisitimu.

C curve (5-10 In) kuchengetedzwa uye kutonga kwemaseketi kubva pakuremerwa uye mapfupi-circuits;dziviriro ye resistive uye inductive mitoro ine yakaderera inrush ikozvino.

D curve (10-20 In) kuchengetedza uye kutonga kwemaseketi kubva pakuremerwa uye mapfupi-masekiti;kuchengetedzwa kwemaseketi anopa mitoro ine yakakwira inrush ikozvino pakuvharwa kwedunhu (LV/LV transformers, marambi ekupwanya).

3. CJB1 ndeyepamusoro ikozvino inodzikamisa mashandiro ekudzikamisa simba rekubvisa nekuda kwepfupi dunhu kusvika pamwero mukuru.
