If this is electrical work, i.e. Wiring that needs to meet code, then yes
they are interchangeable. However if you are depending on the fuse to
protect some equipment that can't stand and over current condition then keep
in mind that a circuit breaker acts like a slow blow fuse. It will stand
load of 140% for quite a while (minuites or more).
