There fuses things called "Slow blow" for handling items and equipment
that uses a lot of current for a short time. These fuses will allow a
surge current to pass before they blow but a steady state current just
over there limit will cause them to blow. A current that is high enough
will cause the fuse to blow just as fast.
I have used "Slow Blow" when trying to find a problem that would blow a
fuse at power on.
I have never really looked at the type of fuses in a mains plug before.
