The ABB 3AUD0000000678 is an ACH580-series HVAC packaged ultra-low harmonic drive with an integrated circuit breaker, sized for 30 Hp light-overload duty at 44 A on a 460 V three-phase supply (UL rating). The R6 frame and IP21 / NEMA Type 1 enclosure mean it's built for indoor panel or equipment-room installation — no washdown protection, so keep it out of wet or dusty zones. The built-in circuit breaker simplifies panel wiring by combining the disconnect and drive in one package, saving a DIN-rail slot and reducing interconnecting cable.
The 30 Hp / 44 A light-overload rating (UL) is the figure that governs motor sizing for fan, pump, and compressor loads typical in HVAC — continuous duty at that current without derating. The 440–480 V three-phase input covers North American 460 V nominal and 480 V distribution; the 50/60 Hz frequency acceptance means the same unit works on 50 Hz or 60 Hz grids, so it's not region-locked. The R6 frame is the physical envelope — verify your panel cutout and mounting footprint against the ACH580 R6 dimensional drawing before ordering.
Integration notes for panel builders
The IP21 / NEMA 1 enclosure allows mounting in a clean indoor panel without additional gasketing. The built-in circuit breaker serves as the line disconnect — no external breaker or fused disconnect required upstream, though local code may still mandate a lockable disconnect within sight. The R6 frame typically requires bottom-entry conduit; plan gland-plate space accordingly. The ultra-low harmonic design meets IEEE 519 THD limits, so no external line reactor or active filter is needed for most HVAC applications.
