What are the limitations for using a motor rated switch as a disconnect.

For example: if I had a 20hp, 460v, 3 phase motor (which has a 27 amp FLC), and proper motor overloads. Could I use a 30A motor rated switch as long as it's rated for 20hp and I have the proper circuit breaker at the panel

I guess, in general, am I interpreting NEC 430.109(A)(1) and 430.110(A) correctly

Thanks
