The two factors to consider are the magnitude and duration of the current. Many fuses are rated in terms of amp squared seconds.

There are several common situations that accidentally bypass a circuit breaker OR uses the wrong circuit breaker. These allows the same magnitude but longer duration current pulse.

There are also weird ones where the wiring includes a pathologically bad amount of resistance. These allow a low magnitude but long duration current pulse. In this case, the crowbar might be able to protect its owner until it burns itself out.
