Ama-Miniature Circuit Breakers (MCBs) angenye yezingxenye ezibaluleke kakhulu ezinhlelweni zesimanje zokusabalalisa ugesi. Aklanyelwe ukunqamula ngokuzenzakalelayo amasekhethi kagesi uma kwenzeka kugcwala kakhulu noma amasekethe amafushane, ukuvimbela ukulimala kwemishini, izingozi zomlilo, nezingozi zikagesi.

I-Air Circuit Breaker idlala indima ebalulekile ekuvikeleni amasistimu kagesi ekulayisheni ngokweqile, kumasekhethi amafushane, nasekuhlulekeni kokusebenza. Kusukela kumafekthri nezakhiwo zezentengiselwano kuya kumasistimu wamandla avuselelekayo nezikhungo zedatha, lezi zinqamuli ziqinisekisa ukusatshalaliswa kwamandla okuzinzile futhi zithuthukise ukuphepha kokusebenza.

Ukukhetha i-circuit breaker efanelekile kudinga ukuhlolwa okuphelele kwamapharamitha wesifunda, izici zomthwalo, indawo yokufaka, nezidingo zokuvikela. Ukucatshangelwa okuyinhloko ukuqinisekisa ukuthi i-voltage elinganiselwe ifana ne-voltage yesistimu, i-current elinganiselwe inkulu kunomthwalo wamanje kodwa ingaphansi komthamo we-conductor ophethe wamanje, kanye nomthamo wokuphuka (i-Icu) uphakeme kunamanje olindelekile wesiyingi esifushane.

Umgomo wokusebenza we-circuit breaker uzungeza umqondo oyinhloko wokuqapha, ukwahlulela, nokwenza. Ngomshini wayo owakhelwe ngaphakathi wokukhubeka kanye nesistimu yokucima i-arc, ifinyelela ukuxhumeka kwesekethe evamile nokulawula ukunqanyulwa kanye nokuphazamiseka okusheshayo kwamasekhethi anephutha. Ngokucacile, ingahlukaniswa ngemodi evamile yokusebenza kanye nemodi yokuvikela amaphutha. Isistimu yokucisha i-arc iyindlela ewusizo ebalulekile eqinisekisa ukuhamba okuthembekile.

Ama-circuit breaker angamadivayisi abalulekile kumasistimu kagesi, anika amandla ukulawulwa kokushintshwa kwesekethe nokuvikela amaphutha okuzenzakalelayo. Asetshenziswa kakhulu kuzo zonke izimo, kusukela kugesi wasendlini kuya kumagridi kagesi aphezulu. Imisebenzi yabo eyinhloko ukuvikela ukulayisha ngokweqile/okufushane kwesekethe/ukuvuza, ukuphepha kwemishini, ukuzinza kokunikezwa kwamandla, nokuvimbela umlilo nokushaqeka kukagesi.
