The ABB 3AUD0000000735 is an ACH580-series HVAC enclosed ultra-low harmonic drive, UL-rated at 15 Hp and 23 A under light-overload use at 460 V, 3-phase. It ships in a NEMA Type 1 enclosure with IP21 ingress protection, sized for the R3 frame. The built-in non-fused disconnect simplifies panel wiring — one less component to spec and mount for branch-circuit isolation.
The 23 A light-overload current at 460 V maps to a 15 Hp motor on standard 460 VAC three-phase supply. The 440–480 V input range covers nominal 460/480 V grids without a buck-boost transformer. Frame R3 defines the mounting footprint and conduit entry pattern — verify against your existing panel cutout if replacing a different frame. NEMA Type 1 means indoor use only; IP21 allows some dripping water but not washdown.
