Guys,
The snap action breakers we use will sustain a 600% overload for a second or two and 300% for a while longer. When you are running CIMs the stall(start) current is 131 amps. If you use normal fuses, they will open with high current motors. While the fuses do have a spec that provides for currents in excess of their rated values, they do not survive three times their current ratings for very long and they are not repairable.

I would suspect any house branded fuses like DB (linked above).
