NEMA sizes are equivalent, however, insofar as the current they will handle. Some 3 pole motor starters list both the single phase and polyphase horsepower ratings, others do not. There is a simple rule that should be followed: A 3 pole motor starter will handle a single phase motor with a horsepower rating ~nly half as large as a 3 phase motor. For example, a NEMA size 2 3 pole motor starter will handle a 15 hp, 230 V, 3 phase motor.
