The ABB 3AUD0000000676 is a packaged HVAC drive in an R6 frame, delivering 20 Hp at 27 A under UL light-overload duty on a 460 V three-phase supply. The integrated circuit breaker and ultra-low harmonic front end mean it meets IEEE 519 without an external filter — a clean drop-in for HVAC chiller or fan arrays where harmonic compliance is specified. Input voltage range is 440 to 480 V at 50/60 Hz, covering the standard North American 460 VAC distribution bus. The NEMA Type 1 enclosure with IP21 protection suits indoor panel mounting; no additional environmental sealing is needed for clean, dry electrical rooms.
Panel integration checklist
R6 frame dimensions govern the enclosure cutout and mounting plate spacing. Verify gland-plate entry for incoming 3-phase power and motor leads — the IP21 rating allows conduit entry through the top or bottom without additional sealing plates in a dry indoor environment. The integrated circuit breaker replaces a separate branch-circuit protective device, saving one DIN-rail slot upstream.
