The ABB ACQ531-01-046A-4+J400 (3ABD00049829) is a 22 kW variable frequency drive in frame size R3, rated for 45 A normal-use output current on a 380-480 V 3-phase supply. It carries IE2 efficiency and IP20 protection in a wall-mounted open-type enclosure.
The 45 A normal-use rating (In) is the figure to match against your motor full-load amps — it governs continuous duty. The light-overload rating of 42.8 A (IlD) applies when the drive is sized for a motor that occasionally exceeds nameplate, but note it is slightly lower than In, not higher; the 22 kW power rating is identical for both duty classes, so the drive is not over-dimensioned for heavy starting. Frequency range covers 47.5 to 63 Hz, which accommodates both 50 Hz and 60 Hz grids without derating.
