Abaphuli beeSekethe zeTyala eziMolded (MCCB)zizinto ezibalulekileyo kuyo nayiphi na inkqubo yombane. Idlala indima ebalulekileyo ekukhuseleni iisekethe nezixhobo kwiimeko zokuxinana kakhulu kunye neemeko ze-short-circuit. Ii-MCCB zenzelwe ukuphazamisa ukuhamba kombane xa kukho impazamo, ukuthintela umonakalo ongakumbi kunye nengozi enokubakho.
Enye yezona nzuzo ziphambili ze-MCCB kukukwazi kwayo ukusingatha imisinga ephezulu xa kuthelekiswa nezinye iintlobo zee-circuit breakers. Zifanelekile kwizicelo zemizi-mveliso ezinzima ezineemfuno eziphezulu zamandla ombane. I-MCCB iyakwazi ukumelana nemisinga emikhulu, iqinisekisa ukusebenza kakuhle nangokukhuselekileyo nakwiindawo ezinzima.
I-MCCB ikwayaziwa ngokuthembeka kwayo nokuqina kwayo. Zenziwe ngezinto ezisemgangathweni ophezulu kwaye zenzelwe ukujongana nobunzima bokusetyenziswa kwemihla ngemihla. Oku kuthembeka kubaluleke kakhulu, ingakumbi kwizicelo ezibalulekileyo apho ukucima kombane kunokubangela ilahleko enkulu yemali kunye nexesha lokungasebenzi. Uyilo lwayo oluqinileyo lunceda ukwandisa ubomi beI-MCCB, ukunciphisa iindleko zokulungisa nezokutshintsha ekuhambeni kwexesha.
Olunye uphawu oluphawulekayo lwe-MCCB kukuba kulula ukuyifaka nokulungisa. Zineendlela zokufakela ezisemgangathweni, ezivumela iingcali zombane ukuba zidibanise ngokulula kwiinkqubo zombane ezikhoyo. Ukongeza, i-MCCB ivumela ukuhlolwa nokusombulula iingxaki ngokulula, ukuqinisekisa ukuba naziphi na iimpazamo okanye imiba inokuchongwa ngokukhawuleza kwaye ilungiswe.
I-MCCB ikwabonelela ngeempawu zokhuseleko eziphuculweyo. Zixhotyiswe ngeendlela zokuthintela ukuphazamiseka okanye ukufikelela okungagunyaziswanga, ngaloo ndlela zinciphisa umngcipheko weengozi zombane. Ukongeza, ii-molded case circuit breakers ziyilwe ngeempawu zokhuseleko ezipheleleyo, kubandakanya ukhuseleko lwe-short-circuit, ukhuseleko lokugqithisa, kunye nokhuseleko lwe-ground fault (kuxhomekeke kwimodeli). La manyathelo okhuseleko aqinisekisa impilo yabaqhubi beenkqubo zombane kunye nezixhobo eziqhagamshelwe kwisekethe.
Ngamafutshane,I-Molded Case Circuit Breaker (MCCB)sisixhobo esibalulekileyo sokukhusela kuyo nayiphi na inkqubo yombane. Ukukwazi kwayo ukuphatha imisinga ephezulu, ukuthembeka, ukulula kokufakela nokugcina, kunye neempawu zokhuseleko eziphuculweyo kwenza ukuba ibe lolona khetho luphambili kwiindlela zokusebenza kwimizi-mveliso. Ukukhetha i-MCCB echanekileyo kubalulekile ekuqinisekiseni ukuba iinkqubo zombane zisebenza ngokufanelekileyo nangokukhuselekileyo, zikhusela izixhobo kunye nabasebenzi kwiingozi ezinokubakho.
