M'dziko lamakono lomwe likupita patsogolo, chitetezo ndi chitetezo cha zomangamanga chakhala chofunikira kwambiri kwa eni nyumba ndi mamenejala. Pamene kufunikira kwa njira zotetezera chitetezo kukukulirakulira, kufunikira kwa magetsi odalirika sikunayambe kofunika kwambiri. Ma Molded case circuit breakers (MCCBs) akhala gawo lalikulu pakuwonetsetsa chitetezo ndi chitetezo cha nyumba, kuzipanga kukhala gawo lofunikira pakukweza chitetezo.
MCCBs adapangidwa kuti azipereka chitetezo chopitilira muyeso komanso chachifupi, kuteteza bwino moto wamagetsi ndi zoopsa zina. Madera amenewa amateteza zipangizo zamagetsi za nyumbayi komanso anthu omwe ali mkati mwa nyumbayi posokoneza kayendedwe ka magetsi pakagwa vuto. Pophatikiza MCCB pakukweza chitetezo chanyumba, eni nyumba amatha kuchepetsa kwambiri ngozi zamagetsi ndikuwongolera chitetezo chonse.
Chimodzi mwazabwino zazikulu za MCCB ndikutha kugwira ntchito zapamwamba zapano, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito zosiyanasiyana kuyambira nyumba zogona mpaka mafakitale. Zomangamanga zake zolimba komanso zotsogola zimapangitsa kuti zikhale zoyenera kukonzanso chitetezo chamakono, kuonetsetsa chitetezo chodalirika ku zolakwika zamagetsi ndi zolakwika.
Kuphatikiza apo, MCCB imapereka mwayi wosinthika ndikusintha makonda, kulola kuphatikiza kosasinthika mumagetsi omwe alipo. Kusintha kumeneku kumawapangitsa kukhala njira yabwino yosinthira nyumba zakale ndikukweza zida zachitetezo popanda kufunikira kukonzanso kapena kukonzanso.
Kuphatikiza pa ntchito zawo zoteteza, ma MCCB amathandizanso kuti mphamvu zamagetsi zisamayende bwino. Madera amenewa amagwira ntchito yofunikira polimbikitsa machitidwe osamalira zachilengedwe mkati mwa nyumba poyendetsa bwino katundu wamagetsi komanso kupewa kuwonongeka kwa mphamvu.
Pamene malamulo oteteza nyumba akupitilira kusinthika, kufunikira kotengera njira zachitetezo chapamwamba monga MCCB sikunganenedwe mopambanitsa. Ndi mbiri yake yotsimikizika yodalirika komanso magwiridwe antchito, MCCB ikuyembekezeka kutenga gawo lalikulu pakukonza tsogolo lakukweza chitetezo.
Mwachidule, zomangira zomangira zimathandizira kulimbitsa chitetezo chanyumba popereka chitetezo champhamvu kuzovuta zamagetsi ndi ma overcurrent. Kusinthasintha kwawo, kudalirika komanso kuthandizira pakuwongolera mphamvu kumawapangitsa kukhala gawo lofunikira pakukweza kwachitetezo chamakono. Pomwe kufunikira kwa nyumba zotetezeka kukukulirakulira, MCCB mosakayikira ikhala patsogolo pakuwonetsetsa kuti nyumba zili zotetezeka m'zaka zikubwerazi.
