Fuse with voltage rating , why ?

[[email protected]]

I notice some fuse maker given voltage rating beside current rating
like 1 amp 250 volt & 1 amp 1000 volt, it make no diffrent on the
voltage as long any current reach more than 1 amp fuse will burn.
My explaination is correct ?

The current rating tells how much current can be passed without
melting. The voltage rating tells how much voltage can be interrupted
once the melt takes place.

No. Once the fuse melts an arc arises which may not extingish fast enough
when the voltage is too high for the fuse at hand.

What good would the fuse be if the 1000 volts were to arc across the open
fuse?
