The ABB 3ABD00057967 is an ACS380-040C drive module in Frame Size R2, rated 5.5 kW normal-duty output at 12.6 A from a 380–480 V 3-phase supply. It carries an IE2 efficiency class and IP20 enclosure, so it's meant for cabinet mounting — no field-installed cover needed, but keep it out of washdown areas. The heavy-duty rating drops to 4.0 kW / 9.4 A, which is the number to use if you're driving a constant-torque load like a conveyor or a positive-displacement pump.
The normal-duty current (12.6 A) covers most variable-torque applications — fans, centrifugal pumps — where the motor rarely pulls full nameplate for long. The heavy-duty figure (9.4 A) is the one that governs for constant-torque or high-starting-duty cycles; if your motor FLA sits between those two curves, size to the heavy-duty column. The 47.5–63 Hz input frequency range means it handles 50 Hz and 60 Hz mains without derating — useful if the same part goes into plants on different grids.
