Fuse failures
Fuse failures
(OP)
Does anyone have a good link for fuse failure analysis? I am looking for a site that describes fuse failure characteristics. In particular, I am evaluating a Gould-Shawmut AX25-40.

RE: Fuse failures
That's what little I know about the subject. I'm sure you want more. Anyone have any links?

Gould has software out there for fuse selection / info. It includes Let-Thru Data and Curves. Check out:

RE: Fuse failures
Thanks for the information. What I was really trying to find was information on fuse failures and how to distinguish between a short circuit fuse blow and an over load fuse blow.
The GouldShawmut site you referenced has good fuse information as does the Bussmann site. In particular, look at the Bussmann Electrical Protection Handbook. Another good reference is Electric Fuses, 2nd Edition by A. Wright and P.G. Newberry.
RE: Fuse failures
"...a short circuit fuse blow and an over load…"
Purely anecdotal "old bastard" advice: if the fuse is warm to the touch, the overload segment of the fuse operated. Obviously, evidence fades relying on this method. If the fuse is cold, the high-speed/short-circuit segment opened the circuit. [This may apply only to dual-element fuses.]
