The ABB 3AUD0000003142 is an ACH580-series HVAC packaged ultra-low harmonic drive with an integrated circuit breaker, rated for 350 Hp / 414 A under UL light-overload conditions at 460 V. That 414 A figure is the continuous output current the drive can sustain for variable-torque loads like fans and pumps — the dominant HVAC application — without derating. The integrated circuit breaker eliminates a separate panel component and reduces the single-point-of-failure count in the power path, which is exactly the kind of simplification a critical-facilities engineer wants when chasing concurrent maintainability.
Line-up and deployment context
Frame R11, 3-phase input 440–480 V, 50/60 Hz. The IP21 / NEMA Type 1 enclosure is clean indoor — suitable for a dedicated electrical room or mechanical penthouse where washdown isn't a concern. The ultra-low harmonic topology (active front end, not just a passive filter) keeps total harmonic distortion well below IEEE 519 thresholds, which matters when the drive shares a transformer with other VFDs or sensitive controls in the same rack. No separate line reactor or DC choke needed for harmonic compliance on most utility feeds.
