are fuses voltage rated?

Can you use a 13A household 240V fuse on your bike as still 13 A 12V?

Re: are fuses voltage rated?

why would you want to? DD says probably not.

Re: are fuses voltage rated?

cause the fuse holder I want to use for my heated gloves takes fuses that are bigger like a 5A one I have that would fit in a plug.

Actually the box of fuses I bought for my bike says 250V so I guess it's only rated for Amps 12V & 240V would both work
(wouldn't put 10,000 V through the same ones though I guess)

Fuses are made very carefully so that the fuse element heats up sufficient to melt the element & break the circuit.

I'm pretty sure that's due to the power flowing through the fuse element. Power is a function of both voltage and current.

So I suspect (but I've never had a reason to test it), that a 230V 13A fuse running at 12V would require more than 13A to generate enough heat to melt the element. How much more, I don't know.

EDIT: Thinking about it, it'd be energy dissipation, which is current & resistance.

So, I wouldn't try it, but I can't remember what effect it would have. Surely there's somewhere open near you that sells the right fuses?

are you needing heated gloves tonight? halfords open til 630 but you will get cold hands getting there.

I reckon it will be fine :D

Your heated grips will keep your hands warm, and if the bike sets alight, at least your bum will be warm too. :D

No. Fuses are pretty precision items, designed for different applications, some allow a certain inrush current, some will not, some will reset. All will be designed for the safe protection of the application in mind without causing risk of fire.
That aside, any fuse is better than none, and so long as it still remains the weakest link in the wiring will offer some protection.

So when I went to Maplins and bought fuses specifically for the bike did they come in a box saying 250V? :smt019

:lol:
