The ABB ACH580-31 (order code 3AXD50001011239) is an ultra-low harmonic drive built for HVAC applications, rated 169 A light-overload under UL (60 Hp) on a 208-240 V three-phase supply. Frame size R8, IP21, NEMA Type 1 enclosure — sized for a wall-mount install. The built-in harmonic mitigation keeps line distortion low enough that you can often skip external filters, which saves panel space and simplifies commissioning.
At 60 Hp on 230 V nominal, this covers a fairly large HVAC motor. The R8 frame carries the physical footprint and the bus structure; if you're replacing an existing drive, check that the mounting pattern and gland plate line up with your panel cutout. IP21 with NEMA 1 means it's indoor-rated, no dripping water, no dust ingress — standard for a mechanical room or rooftop unit enclosure.
