Check out the small panel mounted breakers on this site:http://www.wiringproducts.com/index1.html

I thought I'd read here a few years ago that most breakers had enough
resistance/voltage drop to make them inappropriate for use in our 12v/
14v battery-powered electrical systems. And/or that they were too slow
to protect our increasingly electronic cockpits. Is that not the
case?
