What this drive module is
The ABB 3ABD00057911 is an ACS380-series machinery drive module in frame size R2, built for 380...480 V three-phase input. It delivers 5.5 kW at 12.6 A under normal-duty use, with a heavy-duty rating of 4.0 kW at 9.4 A for tougher loads. The IP20 open-type enclosure means it's meant for cabinet mounting, not out in the weather. Efficiency lands at IE2, which is the baseline for this class.
The normal-duty current of 12.6 A is the number to match against your motor's full-load amps for constant-torque applications like conveyors or pumps. If you're sizing for a heavier cyclic load — say a crusher or a centrifuge — the heavy-duty curve at 9.4 A is the one that governs. There's also a light-overload rating of 12.0 A at 5.5 kW, which covers variable-torque fans and blowers where peak demand is short. The 47.5...63 Hz input frequency range means it handles both 50 Hz and 60 Hz mains without derating.
