The ABB 3AUD0000000696 is an ACH580-series HVAC packaged ultra-low harmonic drive with a non-fused disconnect, rated for 20 Hp at 27 A light-overload use under UL (460 V). It runs on 3-phase 440–480 V input at 50/60 Hz, housed in a frame size R6 with a NEMA Type1 enclosure and IP21 protection.
The R6 frame size and NEMA Type1 enclosure mean it is designed for indoor panel or wall-mount installation where drips and falling dirt are the main concern — IP21 keeps out solid objects larger than 12 mm and vertical water drips, so it suits a mechanical room or rooftop unit enclosure, not a washdown zone.
The integrated non-fused disconnect simplifies compliance with local code requirements for a load-break means of isolation on the line side, reducing the need for a separate disconnect switch in the panel.
