CNC |I-YCB7-63 ye-MCB encinci ye-Circuit Breaker ene-Overload kunye noKhuseleko lweSekethe emfutshane

I-CNC MCB(iswitshi yomoya) inemisebenzi emithathu engundoqo.
1.Isetyenziswa njengokutshintsha kwemela, tyhala phezulu ukuya kumbane kwaye uhlehlise ukucima umbane;
2 Xa ucingo oluphilayo okanye ucingo olungathathi hlangothi lufutshane, luya kuhamba okomzuzwana ukhuseleko olufutshane.
3.Xa umthwalo wombane ugqithise kwiswitshi yomoya, uya kukhubeka ngenxa yokhuseleko lomthwalo ongaphezulu.
Ngokubanzi
1. Ukhuseleko lomthwalo ogqithisileyo
2. Ukukhuselwa kwesiphaluka esifutshane
3. Ukulawula
4. Isetyenziswa kwisakhiwo sokuhlala, kwisakhiwo esingeyondawo yokuhlala, ishishini lomthombo wamandla kunye nezibonelelo.
5. Ngokohlobo lokukhutshwa ngoko nangoko lwahlelwa ngolu hlobo lulandelayo: uhlobo B(3-5)ln, uhlobo C(5-10)ln, uhlobo D(10-20)ln
