Most of ours are now the DIN-mounted double feed that uses the 5x20mm
glass fuses. However, we also have a few legacy sites that use the
automotive blade fuses.
If something new came along, we would use what it uses.

We already stock 5x20mm fuses so keeping with the same form factor
would be nice. Anyone else using those same DIN clip fuse holders
have the same.

I have no strong opinions sir, but if it's a replaceable fuse I do
like the automotive blades because every gas station has them.

I know many of you like PTC resettable solid state fuses. I
don’t recall ever designing one in to anything.
Maybe I did on a phone device years ago, but that would have been
to satisfy a regulatory agency only.
Studying up on them I learn that if you have a 1 amp “hold
current” the “always trip” current is 2 amps.
Not like a fuse, which is pretty well guaranteed to trip at any
current over the rating if you wait long enough.
For a polyfuse, if your load is one amp, you have to have a
design value of greater than 1 amp hold current.
But then it takes double that to actually trip..
And then there is leakage current required to keep it in the
tripped condition.
It does not totally break the circuit.
They are fairly inexpensive compared to glass fuses and fuse
holders.
Could do auto blade fuses too.
Not sure I have the room for anything but a polyfuse though.
Anyone have strong opinions about this?
