The 3AUD0000001572 is an ABB ACH580 HVAC enclosed ultra-low harmonic drive rated 75 Hp at 96 A under light-overload use per UL, on a 460 V three-phase supply. That 96 A figure is the continuous output current the drive can deliver for variable-torque HVAC loads — fans, centrifugal pumps, cooling towers — without exceeding its thermal limits. The 440 to 480 V input range covers common North American 460 V nominal distribution, with tolerance for sag or brownout conditions down to 440 V. Frame R8 means the drive occupies a specific mounting footprint and conduit entry pattern; if you are replacing an existing R8-frame drive, the bolt pattern and bus bar spacing should align. The IP21 and NEMA Type 1 enclosure suits indoor installation where drips and falling dirt are the concern — think mechanical rooms, rooftop unit enclosures, or electrical closets.
Deployment context
The ACH580 is built for HVAC duty — the ultra-low harmonic design (typically <5% THDi) means it meets IEEE 519 without an external filter on most installations, saving panel space and wiring. The built-in non-fused disconnect simplifies code compliance for the service entrance. Expect to land the incoming 3-phase power directly on the disconnect lugs, then feed the drive bus through the internal contactor. The R8 frame typically requires a hoist ring for panel mounting; plan for adequate side clearance for the cooling fins.
