Kev Ua Haujlwm Siab 1P-4P 10kA 1-63A MCB Plug-in hom Mini Circuit Breaker

Kev Piav Qhia Luv:

1. Daim Ntawv Thov: Rau kev tiv thaiv cov cables thiab cov khoom siv tiv thaiv kev overload thiab luv luv circuit.

2. Cov cai dav dav rau kev xaiv MCB.

2.1 Cov ntaub ntawv kev siv ntawm lub network ntawm qhov chaw xav txog:

Cov kab ke earthing, luv luv tam sim no ntawm qhov chaw teeb tsa circuit breaker, uas yuav tsum ib txwm tsawg dua qhov muaj peev xwm tawg ntawm lub cuab yeej no, network voltage ib txwm.

2.2 Muaj 3 yam ntxwv ntawm cov nkhaus rau kev ua haujlwm sib nqus:

B nkhaus (3-5 Hauv) kev tiv thaiv thiab kev tswj hwm ntawm cov circuits tawm tsam cov cables ntev hauv TN thiab IT systems.

C nkhaus (5-10 Hauv) kev tiv thaiv thiab tswj cov circuits tiv thaiv overloads thiab luv-circuits; kev tiv thaiv rau resistive thiab inductive loads nrog qis inrush tam sim no.

D nkhaus (10-20 Hauv) kev tiv thaiv thiab tswj cov circuits tiv thaiv overloads thiab luv-circuits; kev tiv thaiv rau cov circuits uas muab cov khoom thauj nrog cov inrush tam sim no ntawm lub voj voog kaw (LV / LV transformers, breakdown lamps).

3. CJB1 muaj kev ua haujlwm siab tam sim no los txwv lub zog hluav taws xob vim luv luv rau qhov loj tshaj plaws.
