I am looking at fuses from a cable protection standpoint. According to this doc the IEC standards for typical miniature fuses (IEC127-2) can be summarised as:
Why can fast acting fuses tolerate a 210% over-current for 15x longer than slow acting fuses, when in all other cases they are more responsive?
Is this deliberate, or just a consequence of how the fuse operates?
I suppose there is something special about that particular over-current figure, but I'm drawing a complete blank on what it may be....
(And no its not a mistake in the table, I've checked!)
