Using "fuse" which is correct, as in "the fuse fused", is liable to be too confusing
The purpose of a fuse is to protect equipment and wiring against the damaging effects of electrical faults which cause excess currents, and to disable equipment which is faulty. The fuse "blows" when the current carried exceeds the rated value for an excessive time. The higher the overload the shorter the period before the fuse blows. So, equipment which is meant to "draw" 10 amps but which has a short from phase to ground, so it draws, say, 100 amps, will blow its fuse in milliseconds.
