Frame size R11, IP21 with a NEMA Type 1 enclosure. It ships with a non-fused disconnect built in — one less component to panel-mount and wire for the line section. The 302 A light-overload current (250 Hp) is the continuous rating that governs motor sizing for variable-torque HVAC loads — fans, pumps, compressors. Light-overload (110% for 60 s) is the standard duty cycle for these applications; heavy-overload would be a different frame. The 440–480 V input range covers 460 V nominal North American supplies; the drive accepts 50 or 60 Hz line frequency. IP21 and NEMA Type 1 mean it is suited for indoor installation where dripping water or incidental contact is the concern — not washdown, not outdoor.","metaTitle":"ABB 3AUD0000003155 ACH580 HVAC Drive, 302 A, 250 Hp","metaDescription":"ABB 3AUD0000003155 ACH580-3BDR-302A-4 HVAC enclosed ultra-low harmonic drive. 302 A light-overload, 250 Hp, 440-480 V, 3-phase, IP21, NEMA 1.
