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

Kufotokozera Kwachidule:

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

2. Malamulo onse osankha MCB.

a. Deta yaukadaulo ya netiweki pamalo omwe akuganiziridwa: Makina a earthing, mphamvu yafupikitsa yamagetsi pamalo oyikapo chophwanya mafunde, yomwe nthawi zonse iyenera kukhala yochepera mphamvu yophwanya ya chipangizochi, mphamvu yamagetsi ya netiweki.

b. Pali makhalidwe atatu ozungulira a ntchito ya maginito: Chitetezo cha B curve (3-5 In) ndi kuwongolera ma circuits motsutsana ndi zingwe zazitali mu makina a TN ndi IT.

c. chitetezo cha 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 Dcurve (10-20 In) ndi kuwongolera ma circuits ku overloads ndi short-circuits; chitetezo cha ma circuits omwe amapereka katundu wokhala ndi inrush current yambiri potseka ma circuits (LV/LV transformers, breakdown lamps).
