You are "assuming" that every fuse is needed for protection purposes, and that there is no difference. That makes an "ass" out of "u."
No your are sunshine, as any fuse is there to stop component/s from frying up ot even exploding, which can result in fire and even death. So who’s the ass?
(A typical fusers statement, please name one fuse that’s not there for protection.)
