The ABB 3AUD0000000739 is an ACH580-series HVAC enclosed ultra-low harmonic drive in frame size R6. It carries a UL light-overload rating of 40 Hp at 52 A on a 460 V supply, with a 440-480 V three-phase input at 50/60 Hz. The NEMA Type 1 enclosure with IP21 protection suits indoor panel or wall-mount installs where the drive is separated from washdown zones.
The R6 frame includes a built-in non-fused disconnect switch, eliminating the need for a separate disconnect enclosure in the line. The NEMA 1 enclosure allows direct mounting in a clean indoor environment without an additional cabinet; the IP21 rating means tools and fingers stay out, but it is not rated for hose-down or dust-laden air. Input voltage is 440-480 V three-phase at 50/60 Hz — confirm the supply side matches the drive's nominal range before landing power.
