The ABB 3AUD0000000673 is an HVAC packaged ultra-low harmonic drive with an integrated circuit breaker, UL rated for light-overload duty at 7.5 Hp and 12 A output on a 460 V three-phase supply (50/60 Hz). The ultra-low harmonic design reduces line-side distortion below IEEE 519 typical limits without external filters — a fit for commercial HVAC installations where power quality matters.
The 7.5 Hp / 12 A light-overload rating (UL) tells you the continuous motor current the drive can deliver without derating — size your motor nameplate at or below 12 A FLA for a standard fan or pump load. Input voltage range of 440 to 480 V covers common North American 460 VAC three-phase supplies; the 50/60 Hz rating means it works on either grid frequency without adjustment. Frame size R3 and IP21 / NEMA Type 1 enclosure suit indoor panel or wall-mount installation — IP21 protects against dripping water and solid objects larger than 12 mm, but not washdown environments.
Because it is a packaged unit with an integrated circuit breaker, the 3AUD0000000673 is a single-order-code solution for UL-listed HVAC installations — no separate breaker selection needed.
