Yoyesedwa kuti ndi yokwanira kuswa kwafupikitsa kwa ICU

Pali mitundu iwiri ya zizindikiro za mphamvu yosweka yazosokoneza ma circuit: rated ultimate short-circuit break capacity ICU ndi rated operating short-circuit break capacity Ics. Monga chizindikiro chapadera, Ics simangoganizira za breakability yakusweka kwa derar, koma ngati chizindikiro chosweka, ndiko kuti, pambuyo posweka zolakwika zingapo za short-circuit, ikhozabe kutsimikizira kuti ikugwira ntchito bwino.zophulitsira ma circuit breakers opangidwa ndi chipolopolo, payenera kukhala ICU yokwanira kuswa mphamvu yamagetsi yafupikitsa ndikugwetsa switch. Malinga ndi malamulo, ma Ics a chikwama chopangidwachochosokoneza deraIli ndi ma Icu okwana 25%. Pakadali pano, ma Icu ambiri a ma circuit breaker omwe ali pamsika ali pakati pa (50%-75%), kotero pa makina ogawa magetsi omwe safuna magetsi ambiri, Icu yokha ndiyo iyenera kuganiziridwa.
