Izici zekhefu lesifunda.

Izici zokwephula umjikelezo yilezi: i-voltage ue; Kukalwe njengamanje; Uhambo lwamanje lokusetha ukugcinwa ngokweqile (IR noma i-IRTH) kanye nokuvikelwa kwesisu esifushane (im); Kukalwe i-Short-Circuit Circuing Crealing ICU (I-Induclial Circuit Creaker ICU; I-ICN yasekhaya yasekhaya iCn), njll.

1. Kulinganiswe i-voltage esebenzayo (i-UE): Lona ngukuthi ugesi lapho umfukha wokujikeleza usebenza khona ngaphansi kwezimo ezijwayelekile (ezingaphazamiseki).

2. Kukalwe njengamanje (ku): Leli yinani eliphakeme eliphakeme le-breaker breaker elihlome ngokudluliswa okukhethekile okudluliselwe phambili kungamelana nomenzi, futhi ngeke kudlule umkhawulo wokushisa ochazwe yingxenye ebizwa ngengxenye yamanje.

I-4. Kulinganiswe umthamo wokuphuka kwesikhashana (i-ICU noma i-ICN): Ukuqhekeka okulinganiselwe okulinganiselwe kwesekethe kwe-breaker yesekethe okuphezulu kakhulu (okulindelwe) inani lamanje elingaphansi komhlaba elingalinyazwa ngaphandle konakaliswa. Inani lamanje elinikezwe endimeni lisho inani lesikwele lengxenye ye-AC ye-Fault yamanje, kanye nengxenye yesikhashana ye-DC (eqhubeka ivela esimweni esibi kakhulu somjikelezo esifushane) sitholakala njenge-zero. Izilinganiso ze-Industlial Circuit Breaker (ICU) kanye nezilinganiso zesekethe ezifuywayo ezifuywayo (i-ICN) zivame ukunikezwa ngendlela yezimpande ze-ka Root zisho amanani esikwele.
