Makaputsi edunhu akaumbwa(MCCB) zvishandiso zvinodzivirira zvinoshandiswa zvakanyanya mumasisitimu ekugovera magetsi ane voltage shoma. Zvinonyanya kushandiswa kupa dziviriro yemagetsi akawandisa, mapfupi uye pasi pevoltage yemitsetse nemidziyo, uye zvine basa rekuparadzanisa masosi emagetsi. Mutengo wayo unonyanya kukanganiswa nezvinhu zvakaita sebrand, rated current, breaking case uye functional configuration. Kazhinji, mutengo wema "domestic ordinal molded case circuit breakers" anotangira pa50 kusvika 1,000 yuan, pakati pawo zvigadzirwa zvine simba risingasviki 100A zvinowanzo kuve nemutengo uri pakati pe50 ne300 yuan. Mutengo we "large current specifications" (250A kusvika 800A) ungangoita 300 kusvika 3,000 yuan. Zvigadzirwa zvemarudzi epasi rose zvakaita seSchneider Electric, ABB neSiemens zvinodhura zvakanyanya. Mutengo wezvimwe zvigadzirwa zvine njere unogona kusvika zviuru zvakati wandei zveyuan.

Ma "molded case circuit breakers" anonyanya kushandiswa mumafekitori emaindasitiri, zvivakwa zvemabhizinesi, masisitimu ekugovera magetsi edzimba, makabati ekugovera magetsi, masisitimu ekugadzira magetsi e "photovoltaic" uye kuvaka zvivakwa, nezvimwewo. Mundima yemaindasitiri, inogona kushandiswa kuchengetedza mota dzemagetsi, michina yekugadzira uye mitsetse yekugovera magetsi. Mundima yekuvaka, inowanzo shandiswa se "main switch" kana "branch switch" yekabati yekugovera magetsi kuti ive nechokwadi chekuti system yemagetsi inoshanda zvakachengeteka uye zvakagadzikana.
