The ABB 3AXD50000940820 is an LV AC wall-mounted drive from the ACH531 series, rated for 1.1 kW normal-use output at 3.3 A, with light-overload capability at 3.1 A. The frame size is R1, enclosure is IP20 Open Type, and the unit is wall-mounted.
The 1.1 kW normal-use rating (3.3 A) is the continuous motor rating for typical HVAC fan/pump loads. Light-overload at 3.1 A drops slightly but still covers the same power — the drive doesn't need derating for most constant-torque applications. The 380-480 V input covers standard European and North American three-phase supplies. Frame R1 is compact, wall-mount only, so plan for a backplate with clearance for the IP20 enclosure — no DIN rail option.
