The ABB ACS880-01-025A-3 is a wall-mount single drive in the ACS880 inverter family, built around frame size R2 and intended for cabinet mounting in motor-drive panels. It carries the 25 A nominal / 11 kW rating that ABB prints on the nameplate, with a light-overload rating of 24 A / 11 kW, a heavy-duty rating of 17 A / 7.5 kW, and a peak output current Imax of 29 A — the three numbers that actually govern motor pairing, not the single kW figure on the marketing line.
Reading the duty ratings for motor sizing
For a torque-loaded application the heavy-duty 17 A / 7.5 kW figure is the one that limits the drive, because that is the rating ABB guarantees in the heavier duty cycle; the 25 A / 11 kW nameplate is the lighter-duty number and should not be quoted as a constant working point on a hot strip line. Imax of 29 A is the short-duration peak the drive will deliver into the motor for acceleration or shock loads — useful to know for ramp profiles, but not a continuous rating.
Cabinet envelope — heat, airflow, noise
Heat dissipation is 337 W at the rated load, which is the figure the enclosure thermal calculation has to absorb when this drive is mounted in a cabinet near a mill stand or a furnace skid. Cooling airflow is 88 m³/h and the acoustic floor is 51 dBA, which together tell the panel builder that the drive needs a real filtered inlet, not a perforated gland plate, and that it will not be the loudest component in a typical motor control centre. Shipping weight is 20 kg, so it is a two-handed lift into the cabinet — relevant for the wireman's safe-handling step, not a procurement spec.
Where it sits against the next frame down
The natural same-series neighbour is the ACS880-01-017A-3 one R-frame below, which ships at 12 kg — about 8 kg lighter, reflecting the smaller motor current class it serves; choosing between them is a current-rating decision, not a footprint decision.
