What the code resolves to
The ABB ACS800-01-065A-5+P944 is the ACS800-01 wall-mount low-voltage drive rated at the 065A frame, with the +P944 option suffix welded into the MPN string at the factory order stage — meaning the buyer is specifying both the base drive and the option kit as a single BOM line, not two separate part numbers to reconcile on receipt. Listed at 9.07 kgs, the unit is a single-person lift onto a vertical backplate or a two-person carry off a pallet; panel builders tend to bolt it to the backplate before terminating the power cables rather than wrestle the 9.07 kg chassis into a live cabinet.
Option suffix is the BOM-line discriminator
The +P944 trailing the base code is not cosmetic: ABB encodes specific factory-fitted options in that suffix position, so two drives sharing the 065A-5 base can be electrically different on the terminal strip depending on which options shipped. The MPN as quoted is the order code a procurement line should pin to — no silent substitution at receiving without an RFQ re-check against the option matrix.
Same-frame successor candidate
The ACS880-01-052A-5 is the same-form-factor successor-generation unit — wall-mount low-voltage drive in the same footprint class and listed at 9.07 kgs, identical to this ACS800 on the panel-mount dimension a backplate cutout cares about. Where they part is generation: ACS880 is the current ABB platform, ACS800 is the prior one, and the control firmware, parameter tree, and fieldbus option card slot map do not carry over one-for-one, so a panel specified around an ACS800 cannot have an ACS880-01-052A-5 dropped into the cutout and powered up as a like-for-like swap — the parameter download and any safety/IO option cards need re-mapping. The other two ACS880-01 siblings in the same evidence set — ACS880-01-027A-5 at 10.41 kgs and ACS880-01-034A-5 at 10.43 kgs — land in a heavier frame class; they are not same-frame alternates to the 065A unit and are not contrasted here on a like-for-like basis.
Sourcing posture
An RFQ-led quote against this exact 065A-5+P944 string is the procurement move that de-risks the BOM line: matching the +P944 suffix exactly, confirming frame size against the existing backplate, and pinning the listed 9.07 kgs mass for the panel-builder handling plan.
