as most know we had a out of phase 50 amp plug blow our Freedom 458 inverter charger last summer. we replaced the 458 with another rebuilt 458, finished our trip. move 6 months ahead to christmas ti...

Something else to think about regarding a circuit breaker is the arc interrupt capacity of the breaker, versus something like a class T fuse.
a dead short across a large battery bank wired with heavy duty cables could produce thousands of amps. My bank has four batteries in parallel rated at 1600 amps short current each, so that's 6,400 amps if I screw up. My Blue Sea class-T fuse is rated to interrupt an arc of up to 20,000 amps.
By comparison, a Blue Sea dc breaker is rated to interrupt only 6500 amps. If I had more batteries in my bank, a breaker would not stop a short, the DC arc would just burn right through the breaker until something else failed.
