Pamakina amagetsi, MCCB (Molded Case Circuit Breaker) imakhala ndi gawo lofunikira pakuwonetsetsa chitetezo ndi kudalirika kwa kukhazikitsa konse. Ma MCCB adapangidwa kuti ateteze mabwalo kuti asachuluke komanso mabwalo aafupi, kuwapanga kukhala gawo lofunikira pakuyika kulikonse kwamagetsi.
Chimodzi mwazinthu zazikulu za MCCB ndi kuthekera kwake kupereka chitetezo chodalirika chambiri. Izi zimatheka pogwiritsa ntchito magawo oyendera ma thermal-magnetic, omwe amatha kuzindikira zochulukira komanso mabwalo amfupi. Pamene ma overcurrent azindikirika, MCCB idzayenda ndikusokoneza kayendedwe ka magetsi, kulepheretsa kuwonongeka kulikonse kwa magetsi.
Kuphatikiza apo, ma MCCB adapangidwa kuti akhazikikenso mosavuta mukadumpha, kulola kubwezeretsedwanso mwachangu popanda kukonza kwakukulu. Izi ndizofunikira makamaka m'malo azamalonda ndi mafakitale, pomwe nthawi yocheperako imatha kuwononga ndalama zambiri.
Mbali ina yofunika ya MCCB ndi kuthekera kwake kopereka mgwirizano wosankha. Izi zikutanthauza kuti pakachitika cholakwika, a MCCB okha omwe akhudzidwa mwachindunji ndi cholakwikacho ndi omwe angayende, pomwe ma MCCB ena kumtunda sangakhudzidwe. Izi zimatsimikizira kuti mabwalo okhudzidwa okha ndi omwe ali okha, kuchepetsa kusokonezeka kwa magetsi ena onse.
Kuphatikiza pa ntchito yake yoteteza, zotchingira zozungulira zowumbidwa zimakhalanso ndi zabwino zamapangidwe ophatikizika komanso kukhazikitsa kosavuta. Kapangidwe kake kakang'ono kamapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito zosiyanasiyana kuchokera ku nyumba zogona kupita ku mafakitale.
Mwachidule, owumba ma circuit breakers ndi gawo lofunikira kwambiri pamakina amagetsi, kupereka chitetezo chodalirika chopitilira muyeso komanso chachifupi. Kukhoza kwake kupereka kugwirizanitsa kosankhidwa ndi ntchito zokonzanso mofulumira kumapangitsa kukhala chinthu chofunika kwambiri poonetsetsa kuti chitetezo ndi kudalirika kwa kukhazikitsa magetsi. Pamene teknoloji ikupita patsogolo, ntchito ya MCCBs mu machitidwe a magetsi idzakhala yofunika kwambiri, choncho ndikofunikira kuti mainjiniya ndi akatswiri amagetsi amvetsetse kufunika kwawo.
