The ABB 3AXD50000466221 is an LV AC packaged drive rated for 7.5 Hp light-overload at 460 V, drawing 12 A. It includes a disconnect switch and fuses in a Type12 IP55 enclosure. Input is 440... 480 V three-phase at 50/60 Hz, so it lands on standard North American 480 V line power without a transformer.
The 12 A light-overload rating is the number that governs motor sizing — it's the continuous output current the drive can deliver for a 7.5 Hp motor under normal duty. If your load profile is heavier (constant torque or high starting current), verify the drive's heavy-overload curve; the light-overload figure is the one that fits most pump/fan applications.
