I-WTDQ DZ47-63 C63 iSaphuli seSekethe esincinci(3P)
Izaphuli zesekethe ezincinci zizixhobo zombane ezisetyenziselwa ukulawula okwangoku kwaye zisetyenziswa ngokuqhelekileyo kumakhaya, ezorhwebo, nakumashishini. Ukulinganiswa kwangoku kunye nenani le-pole ye-3P libhekisela kumthamo ogqithisiweyo we-breaker circuit, eyona nto ikhoyo ngoku inokumelana nayo xa i-current in circuit idlula i-current rated current.
I-3P ibhekisela kwifom apho i-breaker circuit kunye ne-fuse idibaniswe ukuze yenze iyunithi equkethe utshintshi oluphambili kunye nesixhobo esongezelelweyo sokukhusela (i-fuse). Olu hlobo lwe-breaker circuit lunokubonelela ngokusebenza okuphezulu kokukhusela ngenxa yokuba alugcini nje ukunqumla isiphaluka, kodwa ludibanisa ngokuzenzekelayo xa kukho impazamo ukukhusela izixhobo zombane kumonakalo ogqithiseleyo.
