The part in one breath
The ABB ACS55-01E-09A8-2 is a low-voltage AC drive rated 3 Hp / 2.2 kW. It belongs to the ACS55 family of compact drives aimed at simple speed control. Listed mass is 0.50 kgs — light enough that a single installer lifts it onto the DIN rail without a second pair of hands, and well inside the panel weight budget that pushes the wireman toward a heavier frame only when higher horsepower forces the issue. The part falls under Motors & Motor Controls › Drives › Motor Drives, the branch to source against when a BOM line reads 'AC drive, 3 Hp, 2.2 kW' without further family detail.
