Makaputsi eDunhu Akaumbwa (MCCB)zvinhu zvakakosha mumasisitimu emagetsi. Inoshandiswa sechinochinja otomatiki kumisa kuyerera kwemagetsi kana paine kuwandisa kwemagetsi kana kuti circuit pfupi.MCCBine imba yakaumbwa ine chinja mashandiro uye thermal-magnetic trip unit.
Chimwe chezvakanakira zvikuru zvekushandisaMCCBkugona kwayo kuchengetedza masisitimu emagetsi kubva pakupfuura mwero wemhepo. Chikamu chekufamba chemhepo chinodziya-chemagineti chiri mukati meMCCBInoona kuwanda kwemagetsi uye inogumbura circuit breaker, nokudaro ichidzivirira kukuvara kwemidziyo yemagetsi kana waya. Iyi nzira inoita kuti vanhu nemidziyo vagare vakachengeteka.
MCCBinozivikanwawo nekushanda kwayo kwakasiyana-siyana uye kuvimbika. Inogona kuiswa nyore nyore mune chero sisitimu yemagetsi, ingave yekugara, yekutengeserana kana yeindasitiri. Pamusoro pezvo, yakagadzirirwa kutsungirira mamiriro akaomarara uye kupa mashandiro akasimba kwenguva yakareba.
Imwe mukana weMCCBndiyo nzira yayo inogadziriswa yekufamba. Izvi zvinoreva kuti mafambiro ekufamba anogona kugadziriswa kuti aenderane nezvinodiwa zvemagetsi. Nekugadzirisa mafambiro ekufamba nemazvo, kufamba kusingakoshi kunogona kudzivirirwa, nokudaro zvichivandudza kushanda zvakanaka kwehurongwa.
Pamusoro pezvo,MCCBsdzakagadzirirwa kugadziriswa zviri nyore. Dzinouya nezvinhu zvakasiyana-siyana, zvakaita semacontacts ekuwedzera, ma shunt releases uye ma undervoltage releases, izvo zvinogona kuwedzerwa kana kutsiviwa kana zvichidikanwa. Zvishandiso izvi zvinosanganisa zvinhu zvepamusoro muMCCB, zvichiwedzera kuvimbika kwayo uye mashandiro ayo.
Muchidimbu,Molded Case Circuit Breaker (MCCB)chinhu chakakosha muhurongwa hwemagetsi. Kugona kwayo kudzivirira mhepo yakawanda, kushanduka-shanduka, kuvimbika uye nyore kugadzirisa kunoita kuti ive yakakodzera kushandiswa kwakasiyana-siyana. Ingave yekushandisa mudzimba, mumabhizinesi kana mumaindasitiri, kushandisaMCCBinovimbisa kuchengetedzeka uye kushanda zvakanaka kwehurongwa hwemagetsi ako.
