What lands on the line
The ABB ACS880-01-035A-7 is the wall-mount frame from the ACS880-01 industrial drive family, rated for a 3-phase 525-690 V supply at the input, and it weighs 23.13 kg as a free-standing cabinet-mount unit. It sits in the Motor Drives tier of the path Motors & Motor Controls › Drives › Motor Drives, placing it in the VFD/inverter class rather than soft-starter or servo lines, so the BOM line for an ACS880 inverter cabinet takes this order code.
Reading the headline ratings
At 23.13 kg the chassis is a two-person lift on the panel floor; for a rolling-mill drive room where the drive goes into a higher-IP cabinet near the mill stand, the cabinet hinge and the mounting cleat need to be sized for that mass plus the cable bend relief below it, because the unit's centre of gravity shifts once the line and motor cables land on the gland plate.
Sourcing posture
For a spare on a mill or petrochemical compressor train, the right move is to quote this part against an RFQ using the published weight and voltage class, so the BOM line locks the cabinet footprint and feeder design.
