Ama-Miniature circuit breaker (MCBs) ayizingxenye ezibalulekile ezinhlelweni zikagesi eziklanyelwe ukuvikela kumasekethe ama-overcurrent namafushane. Inkomba yokwethembeka yama-circuit breaker amancane iyisici esibalulekile ekuqinisekiseni ukuphepha nokusebenza kahle kokufakwa kukagesi. Ukuqonda le nkomba kubalulekile konjiniyela bakagesi, ochwepheshe, nanoma ubani ohilelekile ekwakhiweni nasekugcinweni kwezinhlelo zikagesi.
Inkomba yokwethembeka ye-MCB iyisilinganiso sekhono layo lokusebenza ngokungaguquki phakathi kwamapharamitha athile ngokuhamba kwesikhathi. Icabangela izici ezifana nekhwalithi yezinto ezibonakalayo, idizayini, izinqubo zokukhiqiza, nokuhambisana nezindinganiso zomkhakha. Izinkomba ezinokwethenjelwa okuphezulu zibonisa ukuthi ama-circuit breaker amancane mancane amathuba okuthi angasebenzi kahle noma angasebenzi kahle ngesikhathi sokusebenza okuvamile, ahlinzeke ngezinga eliphezulu lokuvikelwa kwezinhlelo zikagesi.
Izinto ezimbalwa ezibalulekile ezithinta inkomba yokwethembeka yama-breaker circuit amancane. Okunye okucatshangelwayo okuyinhloko yikhwalithi yezinto ezisetshenziswa ekwakhiweni kwayo. Izingxenye ezithuthukile nezindlela zokwakha ezimangelengele zithuthukisa kakhulu ukwethembeka kwe-MCB. Ukwengeza, ukunamathela kumazinga emboni kanye nezinqubo zokuhlola ezinzima ngesikhathi sokukhiqiza kubalulekile ukuze kuqinisekiswe ukusebenza okungaguquki.
Idizayini ye-MCB nayo idlala indima ebalulekile ekunqumeni amamethrikhi ayo okwethembeka. Izinto ezinjengomshini wokukhubeka, izinto zokuxhumana kanye nezici ezishisayo ziklanywe ngokucophelela ukuze kuqinisekiswe ukusebenza okuthembekile ngaphansi kwezimo ezihlukene zomthwalo. I-breaker circuit encane eklanywe kahle izoba nenkomba ephezulu yokuthembeka, inikeze umuntu ukuzethemba emandleni ayo okuvikela isifunda.
Ukugcinwa okuvamile nokuhlolwa kubalulekile ukuze kuhlolwe ukwethembeka kwama-MCB ekufakweni kukagesi okukhona. Ukuhlolwa okuvamile, ukulinganisa nokuhlolwa ngaphansi kwezimo zamaphutha ezilingisayo kusiza ukuhlonza noma yiziphi izinkinga ezingaba khona futhi kuqinisekiswe ukuthi i-miniature breaker iyaqhubeka nokusebenza ngaphakathi kwezicaciso zokwethembeka ezishiwo.
Kafushane, izinkomba zokwethembeka zama-circuit breaker amancane ziwukucatshangelwa okubalulekile ekuqinisekiseni ukuphepha nokusebenza kwezinhlelo zikagesi. Ngokuqonda izici ezithonya le nkomba, ochwepheshe bakagesi bangenza izinqumo ezinolwazi lapho bekhetha, befaka, futhi benakekela ama-MCB kuzinhlelo zokusebenza ezihlukahlukene. Ukubeka phambili ukuthembeka kwe-MCB ekugcineni kuba nesandla ekuphepheni kukonke nokusebenza kahle kokufakwa kukagesi.
