What lands on the bench
The ABB ACS550-U1-032A-6 is the 600V class (-6 suffix) member of the ACS550-U1 series, a general-purpose industrial AC drive listed under Motors & Motor Controls / Drives / Motor Drives, weighing 18.14 kgs. Frame is U1, which is the smaller wall-mount envelope in the ACS550 family; the same form factor is used across the whole -U1- line, so panel cutout and gland-plate planning that was done for any other -U1- current rating carries over as long as the voltage class suffix matches.
Same family, different envelope
The closest catalog neighbors are also ACS550-U1 drives, but they sit on a different voltage and option branch: ACS550-U1-096A-4 is the 400V class (-4) at 19.96 kgs, and the +B055 and +L512 optioned units — ACS550-U1-072A-4+B055+L512 at 34.02 kgs and ACS550-U1-059A-4+B055 at 36.29 kgs — pull substantially more mass once the factory-fit options are stacked on.
Handling and panel fit
At 18.14 kgs the unit sits in the bracket where a single installer can shoulder it onto a backplate, but the panel itself should be sized for that static load with vibration in mind — ACS550 drives are fan-cooled, and the U1 frame relies on clearances above and below the heatsink for the derating curve to hold. Mount the drive close to the motor to keep the motor-cable loop short and reduce common-mode noise into the bearing circuit. Ground the cable shield at the drive-end gland plate and leave the motor end floating through a short pigtail for a controlled return path.
Sourcing posture
The order code ships through the standard ABB ACS550 distribution channel and is specified into BOMs against an RFQ — no explicit lifecycle status is documented for this exact MPN, so the close stays on quoted-to-order supply rather than a production-status claim.
