That would have been ideal, however the PTC solidstate fuses do not blow
fast enough.
And doing a solid state current sensor runs up the cost and has it's own set
of problems.
If you are supplying the current it is no problem as you have an easy way to
sense and interrupt the current. But when you are dropping in-line to an
existing circuit you have to be totally isolated, balanced, not affect the
ethernet signal and able to cope with a wide variety of currents and
voltages.

I'm sure you already thought about this, but is it possible to make a
device that recovers automatically after the short circuit has ended
while also responding fast enough to protect the port?
Is it a case where it's possible but costs too much?

We have been shipping for months.
The cost of having a Netonix port repaired is more than the cost of the
fuse.
And then there is the labor and downtime and other intangible expenses
involved in blowing a port.
The prices are lower if you buy from one of my distributors. I don't
encourage anyone to buy off my ecommerce site and pay full list price.
That site is only there to generate sales for distributors.
All of my products have prices based on cost plus margin. Same formula
across the board pretty much. I try to have unique products you can't get
other places. If volume increases on a product, I sometimes adjust the
price down due to the fact that my costs come down. For example, if I am
buying 1000 surge protector PCBs, I may be paying $1 for each. But if I am
only buying 100 of them it may be $2.50.
I recently adjusted the cost down on my 8 circuit tower surge protector for
exactly this reason. Volume picked up, I worked on sourcing and buying and
was able to drop the list price considerably and still maintain my margins.

Hi Chuck,
Great to hear about the new product, the POE Fuse.
Question & critique.
When are these going to be available ?
We would like to see these priced a bit more aggressive...
(At the current pricing, the cost of fusing multiple ports appears to be
exceeding the cost of 'poe switch' it is protecting ! )
Regards.
