Fuses are intended to protect electronic components. Breakers are intended to protect electrical circuits. A master breaker with branch fuses is standard protocol when distributing power to electronics.

Having a fuse inline with a breaker to protect an electric motor is a gross misapplication. Eliminate the fuse.

The breaker has nothing at all to do with protecting the motor. It has everything to do with protecting the electrical circuit to the motor.
