What lands on the floor
The ABB ACS800-U4-0320-5+C136 is a floor-standing AC cabinet drive in the ACS800-U4 family, configured at the 320 A frame with the +C136 option suffix applied to the order code. The shipping mass is 317.51 kg, which puts the unit firmly in palletised, lift-rigged handling territory — not a wall-mount that one person carries to the panel. Classified under Drives / Motor Drives in the ACS800-U4 cabinet-built form factor, with the +C136 option bundle ordered as part of the drive line rather than fitted separately in the field.
Frame delta against the ACS880-01 wall-mount family
That is the swap-out question that actually has teeth: a U4 cabinet drive does not drop into a cut-out sized for an ACS880-01. Anyone treating the two as panel-swap equivalents is reading the wrong line of the family tree. For like-for-like retrofit inside an existing ACS800 cabinet line, the U4 stays the U4.
Sourcing posture
The order code, the +C136 option suffix, and the 320 A frame all need to be quoted as a single line — the option bundle is not a separate accessory and is not a field-retrofittable add-on. Sourcing is handled as a specified-to-order RFQ rather than a shelf pick: confirm the suffix is on the PO, confirm the frame rating on the nameplate matches the BOM, and pull the full suffix string into the MRO record so a re-order two years from now rebuilds the exact configuration.
