What this drive carries and where it goes
The ABB 3AUD0000003143 is an ACH580-series HVAC packaged ultra-low harmonic drive that ships with the circuit breaker integrated — no separate disconnect to panel in. Rated 400 Hp light-overload per UL at 460 V, pushing 477 A continuous. That 477 A figure governs the feeder cable and the upstream protection; the drive itself is sized for the fan and pump loads typical in commercial HVAC, not for high-breakaway-torque conveyors. Input voltage range 440-480 V, 3-phase, 50/60 Hz. Frame size R11, NEMA Type 1 enclosure, IP21 — suitable for indoor equipment rooms where dust and dripping water are controlled, not for washdown or outdoor pit duty.
The 477 A UL light-overload rating is the real selection number — it tells you the drive can deliver that current continuously without tripping on a fan or pump load profile. The built-in circuit breaker saves panel space and wiring labour, but verify the branch-circuit SCCR coordination with your upstream transformer; the breaker's interrupting rating is part of the drive package. Frame R11 means the mounting footprint and gland-plate layout match the ACH580 R11 dimensional drawing — confirm clearance for the incoming cables and the cooling airflow path.
Compliance documentation
The ACH580 series carries UL listing per the UL mark on the nameplate. For RoHS and REACH declarations, ABB provides compliance certificates through their document portal — the drive's order code 3AUD0000003143 is the key for the search. No IEC or CE marks are listed in the spec record, but the UL listing covers North American installations.
