I-fuse esetshenziswayo ivikela okokusebenza ekulimaleni.Uma kwenzeka isigameko esidlulele, okokusebenza kungaba sengozini yokonakala okukhulu noma ukucekelwa phansi.Kulesi simo, i-fuse izomisa ukuhamba kukagesi ehlinzeka ngezinga elimisiwe lokuvikela.Uma i-fuse ithola i-overcurrent (iphutha) ephakeme kunesilinganiso sayo esimisiwe, izosebenza futhi ivuleke.
Amafusi asetshenziswayo ayisidingo sezinhlelo zokusebenza ezifana nezisetshenziswa ezivikelayo ekuhlulekeni kodlame, ukuthuthukisa ikhwalithi yamandla, ukunweba impilo yezisetshenziswa kanye nokukhawulela ukuphela kwesistimu.Ama-Fuse asindisa abasebenzisi inani elikhulu lesikhathi ekushintsheni impahla ebizayo, esebenza isikhathi eside ngokusebenza uma kwenzeka i-overcurrent.
Ama-Fuse asetshenziswa kabanzi futhi akhona ekusebenzeni okuphezulu nangaphansi komhlaba.Uhlu lwamafuse luyahlukahluka phakathi kokuvikelwa kwamanje okuphansi kakhulu (ukuvikelwa ekukhanyeni komgwaqo) yonke indlela eya ekuvikelekeni okuphezulu kakhulu kwamanje (i-solar farm transformer).Imizamo yezemvelo ibeke obala ukubaluleka kokuvikela amathuluzi okusabalalisa ekwahlulekeni ngaphandle kokukhipha imali ekhiqizwe ekusebenzeni.Ukuqamba kanye nokwanda ngaphakathi kwemboni kwandisa i-spectrum yokuhlanganisa.Lokhu kuholela kumafuse amakhudlwana, indawo ezungezile kanye namafuse aphephile emlilweni, namafuse okuvikela akabili.
