I have a Traco power supply where if I short the thing I get a red LED
and a squealing buzzer. It recovers if you remove the short.
I have a Meanwell that clicks inside if you short it, and then resets if
you unplug the AC and plug it back in.
Another Meanwell model resets automatically a few seconds after the
short is removed.
These are all relatively expensive devices, but they all behave in a way
I like. Is it too expensive for switches (or Surge protectors) to
behave like that?

In line, so the cheap thing can blow and you don’t have to replace a
more expensive thing. Plus not all folks will want fusing so it would
drive up the cost of a surge suppressor if I added fusing.
Poly switches are the problem. That POE switch actually protects all
the ports with a polyswitch. But they are very slow to blow. They are
there for fire code reasons, not port protection. If there was a fast
blow polyswitch this problem would not exist.

I've got dumb questions:
Do you picture this going in-line with a surge protector or replacing a
surge protector?
Have you considered a resettable fuse (aka polyswitch)? Nobody has to
truck roll if it cools off and resets in a few seconds.
Thanks,
Adam
