I would like to point out a few things about circuit breakers versus fuses.
1) I made no recommendation one way or the other.
2) I suggested that my intuitive sense that fuses may be faster is quite
possibly contradicted by the efforts of engineering put into both fuses
and circuit breakers.
3) I suggested looking at specifications to really know.
If you find any of that to be bad or dangerous advice, then you are
very sorry.

Specifications for both fuses and circuit breakers are probably
available, which would include the amount of time that it take to
transition from closed to open after an over current condition begins.
When I think about the mechanics of a circuit breaker versus a fuse, and
the amount of mass which has to move in order for the path to open in a
circuit breaker versus a fuse, I find it easier to believe that the fuse
is faster. Some very smart engineers have put a lot of effort into
designing both fuses and circuit breakers, and it may be the results of
their efforts contradict my intuitive sense that a fuse opens faster.
Comparison of specification sheets ought to settle it.
