Thanks both NiHaoMike and NiHaoMike for your suggestions. I had thought of using an op amp, but had wondered about about it's accuracy going from 75mv to something that would trigger a low volt zenner or reference diode, but I suppose they are made to be exceptionally linear.

That HTFS 800-P/SP2 looks really good for the price. A few complications I may have to resolve to use it, but I think it may be the answer I was looking for.

My buss bars are 3/4” square so I will have to round the corners a bit to get the 22mm aperture to fit over. I may not have to amplify if I use a 1.2v reference diode. My aim here is not to do throttle to current measurements but just a simple but quick and sure fire hardware level current limit and protection.
