What you're specifying
The ABB ACS880-01-04A6-2+B056 is a wall-mount low-voltage single drive from the ACS880-01 family, built for 3-phase 208-240 V input and shipped with the +B056 plus-code option applied to the base order code. The +B056 suffix is a real BOM discriminator — it is part of the ordered string, not a generic ACS880-01. At 9.07 kg the unit is a one-person lift, which matters for the wireman planning the cabinet layout and the gland-plate side it lands on.
Sourcing posture
Lifecycle status is not on file for the +B056-coded string. Write the full ACS880-01-04A6-2+B056 into the BOM and RFQ against the plus-code, voltage class, and any firmware or region variant in one pass. No successor cross-reference is on record; specify exact string when sourcing.
