A fuse voltage rating generally refers to its rated

Thus a 120v fuse will stave off at least 120v when it's blown.
I've never heard of a 25v fuse, but a 120v fuse should be fine;
what makes the fuse blow is the I^2*R dissipated power.
Aren't most automotive fuses specified for 32V? But you'll never find
one for 1.5A--automotive fuses tend to be for multiple amps. Most
common fractional-amp fuses are specified at 250V.
