The ABB 3AUD0000000733 is an HVAC-dedicated enclosed ultra-low harmonic drive from the ACH580 family, rated for light-overload use at 7.5 Hp and 12 A on a 460 V three-phase supply. Input voltage range is 440–480 V at 50/60 Hz, making it a direct fit for standard North American 480 V HVAC installations where harmonic mitigation is required without external filters.
The R3 frame size and NEMA Type 1 enclosure (IP21) suit indoor panel or wall-mount installation. The integrated non-fused disconnect simplifies code compliance and reduces external component count in the cabinet.
