The ABB 3AUD0000001554 is a packaged ultra-low harmonic HVAC drive with an integrated circuit breaker, built on the ACH580-3PCR-096A-4 platform. It delivers 75 Hp light-overload output at 96 A on a 460 V supply, sized for commercial HVAC fan and pump loads where harmonic compliance matters without an external filter. Rated for 440...480 V three-phase input at 50/60 Hz, the drive carries a NEMA Type 1 enclosure with IP21 protection — suitable for indoor mechanical-room installation where drips and falling dirt are the main concern, not washdown. Frame size R8 tells the panel builder the mounting footprint and bus-bar layout; the integrated circuit breaker simplifies the line-side protection, saving a separate disconnect enclosure in the BOM.
The 96 A light-overload rating (UL) governs the motor full-load current the drive can sustain continuously without derating. For a 75 Hp, 460 V motor drawing roughly 96 A FLA, this is a direct match — no oversizing needed. The ultra-low harmonic topology keeps total harmonic current distortion below 5 % at full load, which satisfies IEEE 519 without an external line reactor on most installations.
