The ABB 3AXD50000798971 is the order code for an ACH580-01-343A-2, a low-voltage AC wall-mounted drive built for HVAC duty. It runs on 208-240 V three-phase at 50/60 Hz, and in UL light-overload service it delivers 125 Hp at 343 A. The enclosure is IP21 with NEMA Type 1 rating, and it lives in the R9 frame size.
If your load profile is heavy-duty (constant torque, frequent starts), you'd derate from there; the drive's internal thermal model handles the rest. The R9 frame tells you the physical footprint and the mounting hole pattern — wall-mount only, no floor-standing kit needed.
