yes. the 250v just means that's the maximum voltage rating the fuse can handle .. so it can def handle 125v. just not vice versa.
No, the voltage rating should not be exceeded. However, you could use a 250v 10a fuse for a 125v 10a fuse.
Yes, a 250V fuse can replace a 125V fuse if they have the same ampacity rating. The voltage rating is simply the maximum voltage that the fuse is capable of safely interrupting. You can go higher, but you can not go lower. Obviously, the form factor of the fuse must be the same, but that is often the case.
Use the correct fuse and nothing else.
No
Yes, fuses of a higher voltage can be used safely. What is not recommended is to use a lower voltage fuse on higher voltages.
no.. it could damage your electrical components.
It may or may not. And because you are going to a smaller fuse than before, it is safe to try it.
It depends on what you are powering with the circuit, but probably not. The 1.5 amp fuse would blow in normal operation of the device.
Yes but it would be better to put in the right one as the biger fuse wil not protect the unit as well.
The voltage rating of a fuse (in this case 125V or 230V) defines the maximum circuit voltage that the fuse is safe to be used on. A fuse with a voltage rating of 125V should not be used in a circuit with a voltage greater than 125V. If a 125V fuse were installed in a 230V circuit and an overload current occurred, the fuse could explode.
nope
