The ABB 3AUD0000001549 is an ACH580-series HVAC packaged ultra-low harmonic drive rated 100 Hp / 124 A under UL light-overload conditions at 460 V, three-phase, 440-480 V input, 50/60 Hz. It ships in a NEMA Type 1 enclosure with IP21 protection, Frame R8, and includes a non-fused disconnect switch built into the package — one part number for the drive, harmonic filter, and disconnecting means.
The 124 A light-overload rating (UL) governs the motor full-load current it can continuously deliver while still providing 110% overload for 60 seconds — typical for fan and pump loads in HVAC where peak demand is brief. The 100 Hp figure corresponds to a standard NEMA 4-pole motor at 460 V; if your motor nameplate shows a different FLA, the 124 A limit is the binding constraint, not the horsepower. Built-in harmonic mitigation meets IEEE 519 at the drive terminals without external filters — the ultra-low harmonic topology keeps total harmonic current distortion (THDi) typically below 5%, which avoids nuisance tripping of upstream breakers and reduces transformer heating in multi-drive panels.
Deployment context
NEMA Type 1 (IP21) means it is intended for indoor installation where falling dirt and dripping water are not present — standard electrical room or mechanical penthouse placement. The Frame R8 footprint is large enough that panel layout should account for lifting provisions and cable bending radius on the line and load side; the non-fused disconnect occupies the top of the enclosure, so side clearance for the door swing matters. Rated for 50/60 Hz supply, so it works on either 50 Hz or 60 Hz grids without reconfiguration — relevant for projects that may ship to both 50 Hz and 60 Hz regions.
