100A DC Switchable Surface Mount Circuit Breaker Link

I use a couple of Bussman Hi-Amp breakers. They are similar but not identical to the one linked to in the first post. I'm not too happy with their trip characteristics: At 300% load they can take 10 seconds to trip, and at 200%, 40 seconds. Accuracy-wise, at 77 deg F, the trip point is between 100% and 130% of the rating, and they can take a few minutes to trip when only slightly above the trip threshold current. Before choosing a breaker it could be useful to look at the trip curve to see if it will do what you want it to do.
