Madiki ecircuit breakers (MCBs)chikamu chakakosha chechero sisitimu yemagetsi. Inoita basa rakakosha mukudzivirira sisitimu kubva mukuzara kwemagetsi uye mashort circuits.MCBsdzakagadzirirwa kukanganisa kufamba kwemagetsi kana adarika mwero wakachengeteka, kudzivirira kukuvara kwemidziyo newaya uye kuona kuchengetedzeka kwehurongwa hwese.
IyoMCBmudziyo mudiki unogona kukanganisa circuit kana paine chikanganiso. Une switch mechanism uye tripping mechanism. Switch inoshandiswa kuvhara circuit nemaoko, nepo trip mechanism ichingokanganisa otomatiki kufamba kwemagetsi kana paine overload kana short circuit.
Chimwe chezvakanakira zvikuru zvekushandisa ma "miniature circuit breakers" kugona kwawo kudzoreredza nekukurumidza mushure mekugumburwa. Kusiyana nema "fuse", ayo anoda kutsiviwa pese paanoputika,MCBsinogona kugadziriswa zviri nyore nekungobatidza switch zvakare. Izvi hazvingochengeteri nguva chete, asi zvinobvisa kudiwa kwekuunganidza mafiyuzi akawanda.
Pamusoro pezvo,MCByakagadzirirwa kupa dziviriro chaiyo. Inowanikwa mumhando dzakasiyana-siyana dzema "current ratings", zvichibvumira vashandisi kusarudza MCB yakakodzera sisitimu yavo yemagetsi. Izvi zvinovimbisa kutiMCBkufamba padanho rakakodzera remagetsi, zvichidzivirira hurongwa kubva mukukuvadzwa.
Kuwedzera pamabasa avo ekudzivirira, ma "miniature circuit breakers" anoitawo kuti zvive nyore kushanda. Hudiki hwavo hunovabvumira kuiswa nyore nyore paDIN rail, zvichiita kuti vakwanise kuiswa zvidiki.MCBsinopawo vashandisi zviratidzo zvakajeka zvemamiriro ezvinhu (kazhinji kuburikidza nezviratidzo zve LED) kuti zvibatsire mukugadzirisa matambudziko nekugadzirisa.
Zvose,madiki ecircuit breakers (MCBs)chinhu chakakosha mumagetsi emazuva ano. Kugona kwayo kuona nekukanganisa mafungu emvura akawandisa kunodzivirira masystem kubva mukukuvadzwa kunogona kuitika.MCBine hunhu hwekugadziriswa patsva kuri nyore uye dziviriro chaiyo, izvo zviri nyore uye zvakachengeteka. Saka nguva inotevera paunotanga chirongwa chemagetsi, iva nechokwadi chekuti waisawoMCBmuzvirongwa zvako.
