CJB1 18mm Ububanzi 1P 2P 3P 4P I-plug in Circuit Breaker 6ka Single Phase

Incazelo emfushane:

1. Isicelo: Ukuvikela izintambo kanye nemishini ekucindezelweni ngokweqile kanye nokujikeleza okufushane.

2. Imithetho ejwayelekile yokukhetha i-MCB.

2.1 Idatha yobuchwepheshe yenethiwekhi endaweni ecatshangelwayo:

Izinhlelo zokufaka umhlaba, ugesi omfushane endaweni yokufaka i-circuit breaker, okumele uhlale ungaphansi komthamo wokuphuka wale divayisi, i-network voltage evamile.

2.2 Kunezimpawu ezintathu zejika zokusebenza kukazibuthe:

Ukuvikelwa nokulawulwa kwe-B curve (3-5 In) kwamasekethe ngokumelene nezintambo ezinde ezinhlelweni ze-TN neze-IT.

Ukuvikelwa nokulawulwa kwesekethe ngomugqa ongu-C (5-10 In) ngokumelene nokulayisha ngokweqile kanye namasekethe amafushane; ukuvikelwa kwemithwalo yokumelana neyokungenisa ene-inrush current ephansi.

Ukuvikelwa nokulawulwa kwe-D curve (10-20 In) kwamasekethe ngokumelene nokulayisha ngokweqile kanye namasekethe amafushane; ukuvikelwa kwamasekethe ahlinzeka ngemithwalo enomshini wokungena ophezulu lapho kuvalwa isekethe (ama-transformer e-LV/LV, izibani zokuphahlazeka).

3. I-CJB1 inokusebenza okuphezulu komkhawulo wamandla ukuze inciphise amandla okuchithwa ngenxa ye-short circuit ngezinga elikhulu kakhulu.
