Can I replace a fuse with a higher voltage?
You cannot apply a fuse with a max voltage rating that is less than the application voltage. As long as the application voltage is less than 250V, you can replace a 125V fuse with a 250V one.
Can I put a 250V fuse instead of 125V?
For example, a 125V fuse can be replaced with a 250V fuse of equal amplitude while the voltage of the application is 250V or lower, but a a 250V fuse can’t be replaced with a 125V fuse of equal amplitude if the voltage of the application exceeds 125V.
What happens if I put a bigger fuse in my amp?
If you replace a fuse with a higher amp one it will work but create an unsafe circuit. It could cause a failure of the device burn it up, start a fire. The fuse is designed as a safety device. It should not only be the correct amperage but also the correct voltage and fast or slow blow.
Can I use a 240v fuse in a 12v circuit?
It’s still 0 in an ideal fuse, but it’s really somewhere near 0. It’s the amount of current that passes through the fuse that determines if it will blow. 240 volts may be the maximum safe voltage rating for it. 15 amps is 15 amps, and it will be quite OK to use with 12 volts.
Can I use a bigger fuse?
Do not replace a blown fuse with one that has a higher amperage rating. The fuse has a specific amperage rating because it is intended to be the weak link in the circuit to protect the electrical components. A blown fuse indicates excessive current has entered the circuit.

Can I replace a fuse with a higher amp?
Never replace a blown fuse with a higher-amp fuse. Always replace the fuse with one with the specified amp rating. You may install the next-smaller-rated fuse to get you by in a pinch until you can purchase a replacement.
Can I use a 250V fuse for 12V?
I have used 250V fuses on 12V circuits without relevant voltage drop (less than 0.5V). But the quality of the fuses may differ. I can confirm that they were working as some of these fuses blew instantly when short circuited. The best way is to measure the voltage before and after the fuse and see if it’s acceptable.
