I-fuse yokusika i-drop-out kanye ne-load switching cutout fuse iyidivayisi esetshenziswa ngaphandle evikela amandla kagesi aphezulu. Ukuze ixhunywe ne-feeder engenayo yesiguquli sokusabalalisa noma imigqa yokusabalalisa ivikela ikakhulukazi i-transformer noma imigqa ekujikelezeni okufushane kanye nokulayishwa ngokweqile, kanye nokuvula/ukuvala ukulayisha okwamanje.I-fuse yokunqamula ukuphuma yakhiwe ngezisekelo ze-insulat kanye neshubhu ye-fuse, othintana nabo abamile bamiswa ezinhlangothini ezimbili zokusekela isivikeli futhi ukuthintana okunyakazayo kufakwe emaphethelweni amabili e-fuse. ithubhu yokucisha i-arc, ishubhu lephepha elihlanganisiwe le-phenoilc langaphandle noma ishubhu yengilazi ye-epoxy. I-fuse yokusika yokushintsha ukulayisha inikeza othintana naye okunwebekayo okunwebekayo kanye nendawo ebiyelwe yokucisha i-arc yokuvula/ukuvala ukulayisha okwamanje.

Ngokujwayelekile ukusebenza nge-fuselink kuqiniswe ishubhu ye-fuse igxilile ukuze yakhe indawo eseduze.Uma kwenzeka iphutha lesistimu, umphumela wamanje oyiphutha ku-fuse incibilike futhi kwenzeke i-arc kagesi, evumela ishubhu lokucisha i-arc ukuthi lishise futhi liqhume igesi eningi. Lokhu kuzokhiqiza umfutho ophezulu futhi kuphephule i-arc kanye ne-tube.Ngemuva kokuthi i-fuselink incibilike ukuthintana okunyakazayo akusenawo amandla aqinisiwe futhi, inqubo iyakhiywa futhi ishubhu ye-fuse iyaphuma. I-Cutout manje isendaweni evulekile. Uma idinga ukucisha phakathi nokulayisha okusikiwe, u-opharetha kufanele adonse othintana naye onyakazayo ngebha yokufaka evikelayo, lapho kuxhunywana naye okuyinhloko okuqalwayo kanye nomsizi oxhumene ne-static kuthintwa namanje. Ngenkathi udonsa othintana naye oyisizayo kuhlukaniswa phakathi koxhumana nabo abasizayo lapho kwenzeka i-arc kagesi futhi i-arc izonwetshwa endaweni ebiyelwe yokucisha i-arc futhi okwamanje i-arc-cima igesi eqhumayo ukuze ikhiphe i-arc phakathi noziro wamanje odlulayo.
