CJB1 18mm M'lifupi 1P 2P 3P 4P Pulagi Yolowera Circuit Breaker 6ka Single Phase

1. Kugwiritsa Ntchito: Kuteteza zingwe ndi zida kuti zisachuluke kwambiri komanso kuti zisawonongeke.

2. Malamulo onse osankha MCB.

2.1 Deta yaukadaulo ya netiweki pamalo omwe akuganiziridwa:

Makina opangira nthaka, mphamvu yamagetsi yochepa pamalo oyikapo chopumira magetsi, yomwe nthawi zonse iyenera kukhala yochepera mphamvu ya chipangizochi, ndi mphamvu yamagetsi yamagetsi ya netiweki.

2.2 Pali makhalidwe atatu ozungulira a ntchito ya maginito:

Chitetezo ndi kuwongolera ma circuits a B curve (3-5 In) motsutsana ndi zingwe zazitali mu makina a TN ndi IT.

Chitetezo cha C curve (5-10 In) ndi kuwongolera ma circuits ku overloads ndi short-circuits; chitetezo cha resistive ndi inductive loads ndi inrush current yochepa.

Chitetezo cha D curve (10-20 In) ndi kuwongolera ma circuits ku overloads ndi short-circuits; chitetezo cha ma circuits omwe amapereka katundu wokhala ndi inrush current yayikulu pakutseka kwa circuits (LV/LV transformers, breakdown lamps).

3. CJB1 ili ndi mphamvu yochepetsera mphamvu yamagetsi yochepetsera mphamvu yamagetsi chifukwa cha kufupika kwa magetsi mpaka kufika pamlingo waukulu.
