an ordinary 1.25" cartridge fuse

What's one of those?

CPC part number: FS01458 etc.

http://cpc.farnell.com says there is no such part.

To be of any use to people the OP should have given some useful
information, such as the current rating and (perhaps) the breaking
capacity of the fuse. The physical sizes of fuses are not useful.

If the intention was to be a little more coy then whether the
dimension quoted was the length or diameter would have been useful.


The physical size of the fuse IS important when you are considering
spark-gaps etc, which is what caused the dramatic failure in this case.

"1.25" cartridge fuse" is a well known specification, I use them daily.
