Will a 250v fuse work for 125v? The amperage rating on the fuse is the current that the fuse protects, and when that current threshold is exceeded, it blows. The 250V fuse can sustain a higher voltage before it arcs over. So yes, you can use a 250V fuse in place of a 125V fuse as long as the current rating is the same.
Can I use a 250V fuse for 120V?
Fuses are rated in amps. Most fuses for household items are 250V. We are told that we can use 250V fuses of the same amperage rating for our nominal 120V circuits. Thus, if I need a 5 amp fuse for an amplifier I get a 250V 5 amp fuse.
What happens when a 250 volt fuse melts apart?
When a fuse first melts apart, you presumably do get some arcing over the tiny initial gap, but it presumably extinguishes quickly as more metal melts and the gap gets too long. A 250 volt fuse is likely to blow out a 125 volt electronics that was not designed to withstand such high power. You don't want to send 250 volts to a 125 volt circuit.
What happens if you use a 5 Amp Fuse?
First, a 5 amp fuse is meant to withstand a 5 amp current draw for an amount of time determined by the type of fuse, fast or slow blow. If the current draw excedes 5 amps (for an amount of time that excedes the fuse's limit), then the fuse will interrupt the circuit.
Why do we use 240 volt fuses?
It is also common to see 240 volt rated fuses in appliances because the device is designed to work in NA and overseas where the higher voltage is in common use.
Can you use a 250V fuse instead of a 125V fuse?
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.
Does voltage matter on fuses?
Yes, very important! The voltage rating of the selected fuse must be greater than or equal to the circuit voltage. Since fuses have such low resistance, the voltage rating becomes critical only when the fuse is trying to open.
Can I use a 250V fuse instead of 12v?
yes, you can use them, the amp rating does not change. the 250V rating means that they are safe to use in 250V circuit, but may arc at higher voltages. @jsotola, good work, please convert comment to answer.

Can you use a higher voltage rating on a fuse?
The voltage rating of a fuse must be at least equal to or greater than the circuit voltage. It can be higher but never lower. For instance, a 600V fuse can be used in a 208V circuit. The voltage rating of a fuse is a function of its capability to open a circuit under an overcurrent condition.
Can I use higher voltage fuse?
It is designed to protect over- current. 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 use a 12V fuse in a 120v?
The fuse current rating is the highest current it can allow. The wattage, as the current multiplied by the voltage rating, is useless. You can't use a 12 volt fuse rated at 30 amps on a 120 volt circuit which uses 3 amps and you can't use a 120 volt fuse rated at 3 amps on a 12 volt circuit that uses 30 amps.
Can I use 240v fuse for 12V?
The fuse can be used as long as its voltage rating exceeds that of the application it is in ie a 240v 1 amp fuse can be used in a 110v application but a 110v 1 amp fuse should not be used in a 240v application.
Can I use 250v fuse in 24V?
Short answer is YES, the fuse will protect the 24 volt wiring if it is a 250 volt rated fuse..

How many amps is a 250 volt fuse?
The 250 volt semiconductor fuse is a current limiting, very fast-acting, fuse rated to 250 volts AC and up to 250 volts DC. Current ratings range from 1 to 2,500 amps. The maximum interrupting rating, is 200,000 amps AC and 100,000 DC.
Can I replace a fuse with a lower amp?
Do not use a fuse with a lower rating-- don't put a 20 amp fues in a 30 amp circuit--because it probably will blow prematurely. Conversely replacing a 20-amp fuse with one rated at 30 amps is dangerous because it may not blow soon enough and damage an electrical component or start a wiring fire.
