What you're sourcing
The order code ACS800-01-0025-3+P901 carries the +P901 option suffix applied to the ACS800-01 wall-mount AC drive family; the listing title and description both reproduce the full order code ACS800-01-0025-3+P901. It sits in the Motors & Motor Controls › Drives › Motor Drives class, so a buyer landing here is matching a specific drive rating against a motor and panel footprint. The only physical figure on the record is 6.80 kgs, which is the handling weight of the drive as listed — enough to confirm it's a single-person lift for a panel builder staging the unit, not a pallet-scale device.
