Well, ive been doing commercial and industrial electrical for 35 years. All our motors have a fused disconnect. And all motor control panels have multiple fuse protection devices along with heaters . Breakers are always rated 125% over motor loads. Offer limited protection .
but i digress from OP. The states i work in require that we follow nameplate on device. For instance my AC unit has a nameplate that states minimum fuse size. I HAVE to use fuse. If label says minimum OCPD (over current protective device) then you can use a breaker. All this is superseded by whatever manufacturer requires. Most A/C Manufacturers install paperwork i used to read REQUIRED a fused disconnect, so it was never an issue.
