The ABB 3ABD00046357 is an ACH531-01-12A6-4 LV AC wall-mounted drive built for HVAC fan and pump duty. Rated 5.5 kW normal-use output at 12.6 A, it runs on 380–480 V three-phase mains at 47.5–63 Hz. The IE2 efficiency level and IP20 open-type enclosure suit panel-mount installations where ambient stays at or below 40 °C.
The 5.5 kW / 12.6 A normal-use rating (In) is the continuous motor capacity — match it to a 5.5 kW induction fan or pump for full nameplate headroom. Light-overload duty (PlD) stays at 5.5 kW with 12 A output, so there is no extra burst capacity for conveyors or compressors; this drive is specced for variable-torque HVAC loads, not constant-torque machinery. The 8.7 kV·A apparent power output confirms the transformer sizing for the drive's input stage. Frame size B1 determines the physical envelope for panel layout and gland plate planning. Standby loss of 16 W adds to the cabinet heat budget — account for it when sizing ventilation or cooling, especially in a multi-drive enclosure.
