Be sure to ask one of our technical support associates to add your question to our FAQ database.

Q1--Can fuses with an AC voltage rating be used in a DC applications?
A1--Fuses must be rated for the voltage AC or DC in which they will be used. Generally, fuses have a DC voltage rating that is half of the maximum AC voltage rating. (Example: LLSRK_ID - 600 VAC, 300VDC) Consult the factory for specific DC voltage ratings.
Q2--Do you have to derate a fuse to account for the operating temperature?
A2--Yes, This information is in a table on page 4 in the Electronic Designers Guide in the Fuseology section but there is no mention of its existence anywhere outside of this section. A pdf of the page is attached for your convenience.
Q3--Can the fuse voltage exceed the application voltage?
A3--Yes - Fuses are designed for use in circuits at any voltage as long as they don't exceed the fuse's maximum voltage rating. (Exception - medium-voltage fuses from 2,400 to 38,000 volts may only be used at the voltages designated on the fuse's label) The voltage rating of a fuse is a safety rating that should never be exceeded.
