What the order code actually is
The ABB ACS800-U1-0020-5+B056+E202+P907 is a wall-mount AC drive from the ACS800-U1 series, carrying three factory-fitted option codes — +B056, +E202 and +P907 — that ship as a single configured part number rather than three loose accessories.
Class and where it sits in a panel
It is catalogued under Motors & Motor Controls › Drives › Motor Drives, the same class slot occupied by the current ACS880-01 wall-mount generation.
Drop-in question against the ACS880-01 series
The ACS880-01-040A-5, ACS880-01-034A-5 and ACS880-01-027A-5 are same-class ACS880-01 wall-mount drives, but they are a different product generation with a different control board, different option-card slot map and different firmware architecture — the same frame size does not make them a drop-in swap for a panel cut for an ACS800-U1, and the firmware parameter set does not carry across.
Sourcing posture and paperwork
HS classification and country of origin are taken from the ABB commercial invoice at issue, because the option-code suffix changes the customs description even though the catalog category does not.
