Its UL light-overload rating is 50 Hp at 65 A (460 V), so it handles the full motor current of a 50 Hp fan or pump without derating — the harmonic filter is built in, so you skip the external line reactor for IEEE 519 compliance. Frame size R6 and NEMA Type 1 (IP21) enclosure mean it's a floor-standing cabinet ready for indoor installation — no additional enclosure needed for a mechanical room or rooftop mezzanine. The non-fused disconnect serves as a local lockout point, which simplifies the safety circuit for the commissioning engineer.","metaTitle":"ABB 3AUD0000000740 HVAC Drive, 50 Hp, 65 A, 460 V","metaDescription":"ABB ACH580 HVAC enclosed ultra-low harmonic drive, 3-phase, 440-480 V input, 50 Hp / 65 A UL light-overload.
