I'm looking at this DC circuit breaker from Blue Sea Systems: https://www.amazon.com/dp/B000KOTALG
It says "48V DC MAX" and it's a 100A circuit breaker. I've read that these are thermal breakers. 100A @ 48V is 4800W. So it'll trip if you use ~4800W. If I were to use this in a 12V system, 100A @ 12V is only 1200W. If it's a thermal breaker, that won't be enough heat to cause it to trip, right? It would take 400A to reach the same 4800W of heat.
If it's meant for a 48V system, why would they list a "max voltage"?
I already bought it, and now I'm thinking I made a mistake. Can anyone offer any insight?
