CJMD16-63 1-4p 250V-1000V 10ka DC MCB Miniature Circuit Breaker

Inkcazelo emfutshane:

·Uyilo lwangoku
Imbonakalo entle;isigqubuthelo kunye nomqheba kwimilo ye-arc yenza ukusebenza ngokukhululekileyo.
·Phatha umsebenzi wokuhlala usembindini ubonisa isiphene sesekethe
Kwimeko yomthwalo ogqithisiweyo, kwisiphaluka esikhuselekileyo, i-MCB ibamba iihambo kwaye ihlale kwindawo ephakathi, eyenza isisombululo esikhawulezayo kumgca ophosakeleyo.Isibambo asikwazi ukuhlala kwindawo enjalo xa siqhutywa ngesandla.
·Umthamo ophezulu wesekethe emfutshane
Umthamo we-short-circuit ephezulu 10KA kuluhlu olupheleleyo kunye ne-15kA umthamo wokulinganisa ngoku ukuya kwi-40A ngenxa yenkqubo enamandla yokucima i-arc yombane. Ukunyamezela kombane okude ukuya kuma kwi-6000 imijikelo enkosi kwindlela yokwenza ngokukhawuleza.
·Phatha isixhobo sokutshixa
Isiphatho se-MCB sinokutshixwa nokuba kukwindawo ethi “ON” okanye “OFF” ukuthintela ukusebenza okungafunwayo kwemveliso.
·Isixhobo sokutshixa i-terminal yokutshixa
Isixhobo sokutshixa sithintela ukuhla okungafunwayo okanye okuqhelekileyo kweetheminali eziqhagamshelweyo.
