Fuse ya DC ndi chipangizo chomwe chimapangidwa kuti chiteteze mabwalo amagetsi kuti asawonongeke chifukwa cha kuchuluka kwa magetsi, makamaka chifukwa chodzaza mochulukira kapena lalifupi.Ndi mtundu wa chipangizo chamagetsi chamagetsi chomwe chimagwiritsidwa ntchito mumagetsi a DC (direct current) kuti ateteze ku mabwalo opitilira muyeso komanso afupi.
Ma fuse a DC ndi ofanana ndi ma fuse a AC, koma amapangidwa makamaka kuti azigwiritsidwa ntchito pamabwalo a DC.Nthawi zambiri amapangidwa ndi chitsulo chowongolera kapena aloyi chomwe chimapangidwa kuti chisungunuke ndikusokoneza mayendedwe pomwe magetsi apitilira mulingo wina.Fuseyi imakhala ndi chingwe chopyapyala kapena waya womwe umakhala ngati chinthu chowongolera, chomwe chimagwiridwa ndi chothandizira ndikutsekeredwa muchitetezo choteteza.Pamene magetsi akuyenda mu fuseji amaposa mtengo wovotera, chinthu choyendetsa chimatentha ndipo pamapeto pake chimasungunuka, kuswa dera ndikusokoneza kuyenda kwamakono.
Ma fuse a DC amagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikiza magetsi amagalimoto ndi ndege, ma solar, ma batire, ndi makina ena amagetsi a DC.Ndiwo chitetezo chofunikira chomwe chimathandiza kuteteza ku moto wamagetsi ndi zoopsa zina.
