Re: are fuses voltage rated?

Heating effect is caused by the current. The power is irrelevant as most of it is dissipated elsewhere.

Eg as the fuse has very low resistance, the voltage dropped across it is probably only 0.1V or less - the rest of the voltage is all dropped across whatever is actually doing the work.

I'd be happy using a household fuse in a bike. They all blow at particular currents, even if some do take slightly longer.

Difference is an AC fuse is rates in amps RMS (average over the AC cycle) AFAIK, whereas DC is a constant rating. Whether this makes any practical difference or not I have no idea. (perhaps some cooling occurs at less than peak voltage?)

Volts AC RMS is the same heating effect as Volts DC. So no difference in most cases.
