What you're holding
The ABB ACS800-U1-0070-5 is a wall-mount AC drive from the legacy ACS800-U1 series, sitting in the Motor Drives class under Motors & Motor Controls. It carries the ASEA BROWN BOVERI description label on the nameplate and ships as the bare drive module — controller, power stage and integrated cooling in one chassis.
Series context and where it sits in the ABB drive lineup
The ACS800-U1 family was ABB's wall-mount industrial AC drive platform, the predecessor to today's ACS880-01 line — it covered the same low-voltage motor control role (variable torque and constant torque applications in the hundreds-of-kW bracket) but with the DTC firmware and the older control board layout that the ACS880 platform has since replaced. The category trail — Motors & Motor Controls › Drives › Motor Drives — is the standard procurement route for this class, and any RFQ you raise will be filed against that bucket.
Sourcing reality for the ACS800-U1-0070-5
The ACS800-U1 series has been in industrial service long enough that a buyer hitting this order code today is usually chasing a spare for an installed base, not a new design — which is why the part is sourced to order against an RFQ rather than off-the-shelf from the ABB new-product channel.
Where the ACS880-01 sits relative to this code
The ACS880-01 family is listed in the same Motor Drives category — peer order codes ACS880-01-040A-5, ACS880-01-034A-5 and ACS880-01-027A-5 are the wall-mount frames a packaging or machinery OEM would now spec into a new build. Drop-in replacement is not a free swap — the ACS880-01 changes the control terminal layout, the fieldbus option-slot mapping and the parameter ID numbering versus the ACS800-U1, so any panel that was wired around the ACS800-U1-0070-5 needs a terminal-by-terminal recheck before an ACS880-01 is installed in its place.
