If its only needs a 5 amp fuse for a 72 volt system just use a glass tube type.
I believe at 5 amps the glass tube types are rated for 250 volts.
Then at 10 amps and above they drop to 36 volts.
For the 20 amps requirement, the cheapest easiest solution I can think of with out getting a real expensive fuse and fuse holder is to use the glass tube type fuse holder and get a high voltage ceramic body slow blow fuse. Its the same size as the clear glass tube ones but these white tube fuses are rated to much higher voltage. You should be able to get a 20 amp ceramic tube slow blow fuse rated for 250 volts very easy.
I use fuses like this all the time at work.
