Fuse voltage difference?

Is this fuse a safe replacement . fuse 5a 125v to replace 5a 250v ?

If you are using multi-voltage equipment (120 & 220/240) they will need different fuse amps at different voltages. At 120 V you'll need 5 A while at 220 you may need 2.5. Stick with the manufacturer's recommendations

The voltage rating of the fuse is for arc across rating protection in the event of a current overload or a short circuit current fault through the fuse. If the fuse is rated for 125V and installed in a 250V circuit it may not extinguish the arc in the event of an overload in excess of the ampere rating of the fuse, or worse yet a circuit short circuit event. .
