The 3AXD50000705597: This is an ABB ACQ580-PD-065A-4+B058 — an LV AC packaged drive that ships with a disconnect switch and fuses already integrated into a NEMA Type 3R enclosure. Rated for 440...480 V three-phase input at 50/60 Hz, it delivers 65 A continuous under light-overload duty, good for a 50 Hp motor at 460 V (UL).
The 65 A light-overload rating is the number that governs real motor starting and running on a 50 Hp, 460 V three-phase induction motor. The 440...480 V input window covers North American 480 V distribution and European 400 V systems at the high end. The NEMA 3R enclosure means it's rainproof and sleet-resistant — suitable for outdoor wall-mount or washdown areas without a separate cabinet.
