Iziphuli zesekethe ezincinci (ii-MCB)ziyinxalenye ebalulekileyo yayo nayiphi na inkqubo yombane, ziqinisekisa ukhuseleko kunye nokukhuselwa kwezixhobo ezahlukeneyo zombane kunye nezixhobo. Eli nqaku liza kugxila ekusebenzeni, iingenelo kunye nokubalulekaI-MCBkwihlabathi lanamhlanje.
Ii-MCBzenzelwe ukuphazamisa ukuhamba kombane xa kukho ukuxinana okanye i-short circuit, ukuthintela umonakalo onokubakho kwiinkqubo zombane kunye nokunciphisa umngcipheko wemililo yombane. Ngokungafaniyo nee-fuse zemveli,iziphuli zesekethe ezincinciingaphinda isetyenziswe emva kokukhubeka, nto leyo eyenza kube lula kwaye kube neendleko eziphantsi.
Enye yezona nzuzo ziphambili zokusebenzisaiziphuli zesekethe ezincinciubukhulu bazo buncinci. Njengoko igama lisitsho, ii-MCB zincinci ngobukhulu kwaye ziguquguquka ngakumbi ekufakweni. Olu phawu luluncedo ngakumbi kwiindawo apho indawo ekhoyo inqongophele khona, njengeendawo zokuhlala, iiofisi, kunye neendawo zoshishino.
Ukwengeza,Ii-MCBziyakwazi ukubona nokuphendula nakwiimeko ezingaqhelekanga zamandla ombane ezincinci. Zinee-sensors ezakhelwe ngaphakathi ezinokubona umbane ogqithisileyo, ii-short circuits, kunye neempazamo zomhlaba. Nje ukuba kufunyenwe into engaqhelekanga, i-miniature circuit breaker iyawa ngokuzenzekelayo, inqumle umbane kwi-circuit echaphazelekayo.
Olunye uphawu olubalulekileyo lwe-MCB lixesha layo lokuphendula ngokukhawuleza. Ii-MCB zenzelwe ukuphendula kwiimpazamo zombane ngaphakathi kwee-millisecond, ukuqinisekisa ukhuseleko lweenkqubo zombane kunye nezixhobo ezixhunyiweyo. Eli xesha lokuphendula ngokukhawuleza linceda ukuthintela nawuphi na umonakalo onokubakho kwisekethe kwaye linciphisa umngcipheko wokutshayiswa ngumbane kubantu abakufutshane.
Ukubaluleka koiziphuli zesekethe ezincinciayinakugqithiswa. Ezi zixhobo ziyindlela yokuqala yokuzikhusela kwiingozi zombane, zibonelela ngokhuseleko olubalulekileyo kwiinkqubo zombane kunye nabantu abazisebenzisayo. Ukutyala imali kwii-MCB ezisemgangathweni ophezulu kubalulekile ekukhuseleni impahla yakho kwiziganeko zombane kunye nokugcina ixesha elide leziseko zakho zombane.
Konke kwinto enye,iziphuli zesekethe ezincinciziyinxalenye ebalulekileyo yeenkqubo zombane zanamhlanje. Ubungakanani bazo obuncinci, ukukwazi ukubona izinto ezingaqhelekanga, amaxesha okuphendula ngokukhawuleza kunye nokusebenza okuhlengahlengiswayo kuzenza zibe luncedo kakhulu. Ngokutyala imali kwi-MCB ethembekileyo, unokuqinisekisa ukhuseleko, ukusebenza kakuhle kunye nobude bexesha lenkqubo yakho yombane.
