FuseNanone yitwa fuse, melt. Fuse y'amazu yose ishyirwa nyuma y'icyuma gipima ingufu z'amashanyarazi, kandi fuse ya porcelain ikoreshwa muri rusange. Ubu nk'uburinzi bw'inzu, utumashini dukoresha amashanyarazi dukunze gukoreshwa aho gukoresha fuse. Amazu yo mu mijyi n'ay'icyaro, amazu ashaje yo mu mijyi n'andi mazu yo mu cyaro na yo akoresha fuse nk'uburinzi rusange. Byongeye kandi, ibikoresho byinshi byo mu rugo bifite fuse, nka televiziyo z'amabara, amafuru ya mikoroonde, amakaseti, ibyuma bikonjesha, imashini zimesa, nibindi, nk'uburinzi bw'ibikoresho byo mu rugo.
Fuzizikoreshwa cyane cyane mu kurinda ibikoresho by'amashanyarazi n'imiyoboro yabyo. Kubera ko iyo ibikoresho by'amashanyarazi cyangwa umurongo wabyo ufite ikibazo cya "short-circuit", umuriro uri mu ruziga wiyongera vuba, kandi fuse ihita ihuhwa, bityo ikarinda ibikoresho by'amashanyarazi n'umurongo byangirika cyangwa bigatuma impanuka irushaho kwaguka.
Itsindaicyuma gifungaishobora kandi kugira uruhare runaka mu kwiyongera kw'ibikoresho by'amashanyarazi n'imiyoboro y'amashanyarazi. Iyo umuvuduko w'amashanyarazi urenze inshuro ebyiri z'umuvuduko w'amashanyarazi wa fize, fize ishobora guhuha mu minota 3 kugeza kuri 4, bityo ishobora no kugira urwego runaka rwo kurinda umuvuduko w'amashanyarazi. Ariko ubu bwoko bw'uburinzi ntiburi bwizewe cyane, kuko imiterere ya fize ifite ikwirakwira rikomeye, nubwo fize zifite imiterere imwe zifite imivuduko itandukanye ya fize.
