Why does my PAMO2 motor operator for the P frame breaker keep blowing fuses?

It may be one of several things. If the CPT control power transformer is undersized (it should be at least 500 VA), if multiple devices are operated simultaneously pulling down the line voltage, fuses can blow, or if the mechanical force required to operate the operator has increased, it could blow fuses.
The specified fuse is Buss MDA-7
