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.

The fuse is marked : 50 C 5 A I bought some 5.0 A fuses, but they are physically smaller (63 V DC). The Digikey part # for the fuses I bought is 283-2452-1-ND. thanks, Mad Dog ---------- --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).
