The ABB 3AUD0000000716 is an ACH580 HVAC enclosed ultra-low harmonic drive with an integrated circuit breaker, sized for 20 Hp at 460 V with 27 A output current under UL light-overload duty. It's a three-phase unit running on 50/60 Hz supply, rated for 440...480 V input. Frame R6, NEMA Type 1 enclosure with IP21 protection — meaning it's meant for indoor installation where drips and falling dirt are the main concern, not washdown or outdoor exposure.
The 20 Hp / 27 A light-overload rating is the UL-listed continuous output for a typical HVAC fan or pump load — that's the number you spec against the motor nameplate, not the peak or heavy-duty figure. The 440...480 V input range covers standard North American 460 VAC three-phase distribution without a buck-boost transformer. NEMA Type 1 / IP21 means it's suitable for clean, dry indoor environments; no washdown or outdoor protection.
