Kwihlabathi lanamhlanje elikhula ngokukhawuleza, ukhuseleko lwesakhiwo kunye nokhuseleko luye lwaba yinto ephambili ephambili kubanini bezakhiwo kunye nabaphathi. Njengoko imfuno yamanyathelo okhuseleko oluphezulu iqhubeka ikhula, imfuno yeenkqubo zombane ezithembekileyo ayizange ibaluleke ngakumbi. I-Molded case circuit breakers (MCCBs) ibe yinto ephambili ekuqinisekiseni ukhuseleko kunye nokukhuselwa kwezakhiwo, okwenza zibe yinxalenye ebalulekileyo yokuphucula ukhuseleko.
Ii-MCCBs zenzelwe ukubonelela ngokugqithisileyo kunye nokhuseleko olufutshane, ukuthintela ngokufanelekileyo umlilo wombane kunye nezinye iingozi. Ezi zaphuli zesekethe zikhusela iziseko zombane zesakhiwo kunye nabantu abangaphakathi kwisakhiwo ngokuphazamisa ukuhamba kombane xa kukho impazamo. Ngokubandakanya i-MCCB ekuphuculeni ukhuseleko kwisakhiwo, abanini bezakhiwo banokunciphisa kakhulu ingozi yeengozi zombane kunye nokuphucula ukhuseleko jikelele.
Enye yeenzuzo eziphambili ze-MCCB kukukwazi ukuphatha amandla aphezulu angoku, okwenza ukuba ilungele uluhlu olubanzi lwezicelo ukusuka kwizakhiwo zokuhlala ukuya kwizakhiwo zoshishino. Ukwakhiwa kwayo okuqinileyo kunye neempawu eziphambili zenza ukuba zilungele ukuphuculwa kokhuseleko lwanamhlanje, ukuqinisekisa ukhuseleko oluthembekileyo kwiimpazamo zombane kunye nokungahambi kakuhle.
Ukongeza, i-MCCB ibonelela ngokuguquguquka okuphuculweyo kunye neendlela zokwenza ngokwezifiso, ivumela ukudityaniswa komthungo kwiinkqubo zombane ezikhoyo. Oku kuziqhelanisa nemeko kubenza babe sisisombululo esisebenzayo sokulungisa ngokutsha izakhiwo ezidala kunye nokuphuculwa kweempawu zokhuseleko ngaphandle kwesidingo sohlengahlengiso olubanzi okanye ukutshintshwa.
Ukongeza kwimisebenzi yabo yokukhusela, ii-MCCBs nazo zinegalelo ekusebenzeni kwamandla kunye nokuzinza. Aba baphuli beesekethe badlala indima ebalulekileyo ekukhuthazeni izenzo zokusingqongileyo ngaphakathi kwezakhiwo ngokulawula ngokufanelekileyo imithwalo yombane kunye nokuthintela ukuchithwa kwamandla.
Njengoko imimiselo yokhuseleko kwisakhiwo iqhubeleka nokuvela, ukubaluleka kokwamkelwa kwamanyathelo okhuseleko akumgangatho ophezulu njenge-MCCB akunakubaxwa. Ngerekhodi eqinisekisiweyo yokuthembeka kunye nokusebenza, i-MCCB kulindeleke ukuba idlale indima ebalulekileyo ekubumbeni ikamva lokuphucula ukhuseleko lokwakha.
Isishwankathelo, i-molded case circuit breakers inceda ukunyusa ukhuseleko lwesakhiwo ngokubonelela ngokhuseleko oluluqilima kwiimpazamo zombane kunye ne-overcurrent. Ukuguquguquka kwabo, ukuthembeka kunye negalelo ekusebenzeni kakuhle kwamandla kubenza babe yinxalenye ebalulekileyo yokuphuculwa kokhuseleko lwangoku. Njengoko imfuno yezakhiwo ezikhuselekileyo iqhubeka ikhula, i-MCCB ngokungathandabuzekiyo iya kuhlala iphambili ekuqinisekiseni ukhuseleko lokwakha kwiminyaka ezayo.
