Probably only the UL listing. If the nameplate says use HACR circuit
breaker, then that is what is required.

John has the right answer. Fortunately most modern molded case
breakers are rated HACR these days so a "regular" breaker is probably
fine.

Allows a brief current surge, for starting the motor. As opposed
to a breaker for other things, which trips more quickly in case
of over current.
