??? The voltage rating of a fuse is VERY important. I don't know
how much damaged Marine electronic gear I've seen over the years
where someone used a 120v fuse instead of a 12v fuse of the same
amperage. P = VI, power equals volts times amps.

Hi!

There would not normally be a voltage rating for a fuse, because they
work on the amount of current passed, not the voltage.  5 amps at 1 volt
is the same as 5 amps at 110 volts as far as a fuse is concerned.  A
fuse has a very low resistance, and works (blows) only on the basis of
the differential voltage between the two ends, not the absolute voltage.
I=V/R if I remember correctly.

There may of course be other considerations, such as size or rate of
blow, but a voltage rating will normally only refer to the amount of
insulation in the construction of the fuse, etc., which prevents arcing
over to other nearby components.

Have a great New Year,

Andy
