Abaphuli beeSekethe zeTyala eziMolded (MCCB)zizinto ezibalulekileyo kwiinkqubo zombane. Isetyenziswa njengesitshixo esizenzekelayo ukuphazamisa ukuhamba kwamandla ombane xa kukho ubuninzi bombane okanye i-short circuit.I-MCCBIqulathe indlu ebunjiweyo, indlela yokutshintsha kunye neyunithi yokuhamba ngemagnethi eshushu.
Enye yezona nzuzo ziphambili zokusebenzisaI-MCCByikhono layo lokukhusela iinkqubo zombane kwi-overcurrent. Iyunithi yokuhamba nge-thermal-magnetic ngaphakathiI-MCCBIbona umbane ogqithisileyo ize iphazamise i-circuit breaker, ngaloo ndlela ithintela nawuphi na umonakalo kwizixhobo zombane okanye kwiintambo. Olu phawu luqinisekisa ukhuseleko lwabantu kunye nempahla.
I-MCCBikwaziwa nangokusebenziseka kwayo okuguquguqukayo nokuthembeka. Zingafakwa lula kuyo nayiphi na inkqubo yombane, nokuba yeyokuhlala, yorhwebo okanye yemizi-mveliso. Ukongeza, zenzelwe ukumelana neemeko ezinzima kwaye zibonelele ngokusebenza rhoqo kwixesha elide.
Enye inzuzo yeI-MCCByindlela ehlengahlengiswayo yokutshintsha umbane. Oku kuthetha ukuba umbane ohambayo unokwenziwa ngokwezifiso ukuhlangabezana neemfuno ezithile zenkqubo yombane. Ngokumisela umbane ohambayo ngokuchanekileyo, umgama ongeyomfuneko unokuthintelwa, ngaloo ndlela kuphuculwe ukusebenza kakuhle kwenkqubo.
Ukongeza,IiMCCBzenzelwe ukugcinwa lula. Ziza nezixhobo ezahlukeneyo, ezifana nee-assistant contacts, i-shunt releases kunye ne-undervoltage releases, ezingongezwa okanye zitshintshwe njengoko kufuneka. Ezi zixhobo zidibanisa iimpawu eziphambili kwiI-MCCB, iphucula ngakumbi ukuthembeka kwayo kunye nokusebenza kwayo.
Ngamafutshane,I-Molded Case Circuit Breaker (MCCB)licandelo elibalulekileyo kwinkqubo yombane. Amandla ayo okukhusela umbane omninzi, ukuguquguquka, ukuthembeka kunye nokulula kokugcinwa kwayo kwenza ukuba ilungele ukusetyenziswa ngeendlela ezahlukeneyo. Nokuba yeyokusetyenziswa emakhaya, kurhwebo okanye kwimizi-mveliso, isebenzisaI-MCCBiqinisekisa ukhuseleko nokusebenza kakuhle kwenkqubo yakho yombane.
