Alright. Just in case you're ever in a bar room bet situation with it riding on "what's better at protecting my car, a fuse or circuit breaker?" There are times when a circuit breaker is really better than a fuse and times when a fuse is really better than a circuit breaker. Circuit breakers get old and pop off easier, and their derating curves can fool you under a hot hood, but, on the other hand, some circuit breakers can trip faster because of the magnetic field of a sudden fault to ground, as opposed to just heating up and tripping off thermally. Soooooo, never place a bet either way on a bar room bet as to which is better... you're just being set up to pay for the next round of drinks.
