The ABB 3AUD0000000737 is an ACH580-series HVAC enclosed ultra-low harmonic drive with a non-fused disconnect, rated for 25 Hp light-overload use at 34 A on a 460 V three-phase supply. The R6 frame size and Type 1 NEMA enclosure with IP21 protection suit it for indoor panel or machine-mounted installation where harmonic mitigation is required without an external filter.
The 34 A output current at 460 V under light-overload duty (UL listing) sets the motor capacity: it drives a 25 Hp induction motor continuously. The 440–480 V input range covers standard North American 460 V and 480 V grids; the 50/60 Hz rating makes it usable on either frequency without derating. The built-in ultra-low harmonic design keeps total harmonic distortion (THD) below 5% at full load, which avoids nuisance tripping of upstream breakers and meets IEEE 519 guidelines without an add-on filter.
