The ABB 3AXD50000465903 is an ACQ580-PD-023A-4 LV AC packaged drive — a VFD with disconnect switch and input fuses already integrated, sized for a 3-phase 440–480 V supply. UL light-overload rating lands at 15 Hp / 23 A, which is the number that governs motor sizing on a North American panel. Frame size R2 keeps the footprint compact for a 15 Hp drive; IP21 and NEMA 1 enclosure suit indoor, non-condensing environments.
The UL light-overload rating (15 Hp, 23 A at 460 V) is the practical ceiling for continuous motor duty on a 460 V supply. Frame size R2 determines the mounting hole pattern and conduit entry locations — verify against the existing panel cutout if replacing an older drive. Input voltage range 440–480 V covers common North American 460 V and 480 V systems; 50/60 Hz compatibility means the same unit works on 50 Hz export installations without derating the input section.
