Short answer : Choose the one with a voltage rating at least equal to
the full voltage of the circuit in which it is to be used.
Longer one : Although a fuse is primarily concerned with current, the
voltage is not entirely irrelevant. If it blows due to excessive load
current, and IF the supply voltage is high enough, it could conceiveably
arc over between the two ends of the fuse instead of shutting down the
circuit completely (though IMHO this would be rare).
The 125V type is intended for use with mains supplies upto 110-120V,
while 250V fuses are suitable for 220-240V systems (European, Asian
etc.). No harm in using a higher-rated fuse (voltage-wise) in a low-
