Utwuma duto two gusohora amashanyarazi (MCB)ni igice cy'ingenzi cy'imikorere y'amashanyarazi ya none. Nk'uko izina ribigaragaza, ni icyuma gito cy'amashanyarazi gica umuriro mu buryo bwikora iyo hagaragaye ikibazo. Iyi nkuru izasuzuma akamaro n'imikorere ya miniature circuit breakers mu kubungabunga umutekano w'amashanyarazi.
Imwe mu nyungu z'ingenzi zo gukoreshautumashini duto two gukata uruzigani ubushobozi bwabyo bwo kurinda imiyoboro y'amashanyarazi ikabije n'imiyoboro migufi. Ibi bikoresho byagenewe gucunga igipimo cy'amashanyarazi runaka, bigamije kwemeza ko umuyoboro unyura muri iyo miyoboro utarenze urugero rwagenwe. Mu gihe habayeho umuvuduko mwinshi cyangwa umuvuduko mugufi,MCBingendo, guhagarika urujya n'uruza rw'amashanyarazi no gukumira ibyago byose bishobora kubaho nko gushyuha cyane cyangwa inkongi z'amashanyarazi.
Utwuma duto tw'amashanyarazizikoreshwa mu buryo butandukanye, kuva ku miturire kugeza ku nganda. Mu bwubatsi bw'amazu,MCBzikunze kuboneka mu tubati two gukinga imiyoboro y'amashanyarazi mu bice bitandukanye by'inzu. Ibi bituma byoroha kumenya no gutandukanya imiyoboro y'amashanyarazi ifite ibibazo, bigagabanya ibyago byo guhura n'impanuka z'amashanyarazi.
Mu nganda, utumashini duto dukoresha imiyoboro y'amashanyarazi (miniature circuit breakers) dukoreshwa mu kurinda imashini n'ibikoresho. Ibi bikoresho ntibirinda gusa imiyoboro y'amashanyarazi, ahubwo binahagarika ingufu mu gihe cy'amashanyarazi adasanzwe, bikarinda kwangirika kw'imashini zihenze. Mu kubona vuba no gutandukanya imiyoboro y'amashanyarazi ifite ibibazo,MCBbifasha mu gukomeza gukora neza no gukumira igihe gitwara amafaranga menshi.
Imiterere y'ibikoresho bigabanya umuvuduko w'amashanyarazi bigira uruhare runini mu kurinda umutekano no kwizerwa kw'ibikoresho by'amashanyarazi. Hari ubwoko butandukanye bwaMCBguhitamo, buri kimwe gifite umurongo wacyo w’inzira ugaragaza umuvuduko w’ingaruka ku moko atandukanye y’amakosa. Ibi bituma bishoboka guhitamo MCB ijyanye n’ibisabwa byihariye bya circuit, yaba ari electronics ishobora gukurura cyane cyangwa moteri ifite inrush currents.
Byongeye kandi,utumashini duto two gukata uruzigabifite akarusho ko kongera gukoreshwa, bitandukanye na za fiyuzi zigomba gusimburwa iyo zaguye. Iyo ikibazo kimaze gukemurwa n'ikibazo cy'ibanze kigakemuka,MCBishobora kongera gukoreshwa n'umuntu ukoresheje intoki ukongera kuyicana. Iyi porogaramu yongera uburyo bworoshye kandi ikagabanya ikiguzi cyo kuyisana mu gihe kirekire.
Ikindi kintu cyo gutekerezaho mugihe uganirautumashini duto two gukata uruzigani ingano yazo nto. Bitandukanye n'ibyuma bisanzwe bigabanya umuvuduko w'amashanyarazi binini kandi bitwara umwanya munini,MCBni nto kandi zishobora gushyirwa mu buryo bworoshye imbere mu tubati two gusimbuza. Ibi bituma ziba amahitamo ya mbere aho umwanya ari muto, nko mu mazu yo guturamo cyangwa ay'ubucuruzi afite utubati duto tw'amashanyarazi.
Mu gusoza,utumashini duto two gukata uruzigani ingenzi mu kubungabunga umutekano w'amashanyarazi mu bikorwa bitandukanye. Ubushobozi bwazo bwo kurinda umuriro ukabije n'imiyoboro migufi, hamwe n'ibintu bishobora kongera gukoreshwa ndetse n'ingano nto, bituma ziba ingenzi mu buryo bw'amashanyarazi bugezweho. Haba mu rugo, mu biro cyangwa mu nganda,MCBkugenzura imikorere y'insinga mu gihe bigabanya ibyago bishobora kubaho.
