Thank you, I am glad to hear that the 250V fuse will work. I am just replacing a fuse in a 120V device that burned out. I am not trying to convert it for 250V use.

All of the answers are correct. I am an industrial electrician. All fuses should be rated for a higher voltage than what is being used. It is the current that you really need to be concerned with. For instance, on 24 Volt controls all of our fuses are rated at 120V. on 220V. circuits we use 600V rated fuses.

If it is to be operated on the same 120V circuit, and all you have is a 250V rated fuse, use 10A. The voltage rating means that the fuse can safely operate at that voltage, so one with a higher voltage rating has an even better safety margin.
But if you are taking about changing a 120 volt device to operate on 240 volts (say you are taking it to England, where standard household outlets are 240 volt), you would then replace it with a 5 amp fuse. But there is more to converting a device to operate on a different voltage than just replacing the fuse. Read the instructions for the device to find out how or if you even can do this without an external transformer.

A fuse blows when more electrical current goes through it than is allowed. That means its operation is very voltage insensitive and a fuse rated for a higher voltage would work fine at lower voltages. Use the same amp rating and a voltage rating at least as high as is used in the circuit.

Installing a new fuse or circuit breaker with anything other than the same size that was in is never never a good idea. It will either blow all the time or never blow at all, well maybe after the fire starts it will. Get an electrician to look at it, they will know where to get replacements or how to modify the box to accept another brand of the SAME SIZE !!

10 amp. As long as the voltage is higher than the circuit you are fine.

the fusing is usually rule of thumb 10% of the voltage....250V=25A
