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

Kufotokozera Kwachidule:

1. Kugwiritsa ntchito: Kuteteza zingwe ndi zida kuti zisachuluke komanso mayendedwe amfupi.

2. Malamulo onse posankha MCB.

a. Deta luso maukonde pa mfundo amaona: The earthing kachitidwe, yochepa dera panopa pa dera wosweka unsembe mfundo, amene nthawi zonse kukhala zosakwana kuswa mphamvu ya chipangizo ichi, maukonde voteji yachibadwa.

b. Pali ma curve atatu ogwiritsira ntchito maginito: B curve(3-5 In) chitetezo ndi kuwongolera mabwalo kutengera zingwe zazitali mu TN ndi IT.

c. curve (5-10 In) chitetezo ndi kuwongolera mabwalo motsutsana ndi zolemetsa komanso zazifupi; chitetezo kwa katundu resistive ndi inductive ndi otsika inrush panopa.

Dcurve (10-20 In) chitetezo ndi kuwongolera mabwalo kuti asatayike komanso mafupipafupi; chitetezo cha mabwalo omwe amapereka katundu wothamanga kwambiri pakutseka kwa dera (LV / LV thiransifoma, nyali zowonongeka).
