What the order code covers
The ABB ACS880-01-156A-5+B056+D150 is a wall-mount industrial drive from the ACS880-01 family, with the +B056 and +D150 option suffixes carried on the same order string. It lands in the Drives / Motor Drives slot of the ABB low-voltage drive line — the same cabinet-mount form factor used across the ACS880-01 series for direct-on-line motor control in panels. The 156A frame appears at the heavy end of the ACS880-01 wall-mount range; the order string's 156A current rating is what the +B056 and +D150 options sit on top of.
Sourcing posture and second-source question
The base 156A frame, ACS880-01-156A-5, is the only same-current peer carrying the same input class on record; the +B056 and +D150 options are what make this order string distinct from that base unit. For a panel originally specified around the bare ACS880-01-156A-5, this configuration is the same frame and input class plus the two option codes — wiring footprint matches, but the option code set has to be verified against the BOM before substitution.
Integration read for the panel builder
At 58.06 kgs the unit needs hoist eyes or a panel-side lift plan, and the cabinet should be specified with the 156A frame's footprint rather than the smaller 065A or 040A footprints shown elsewhere in the family. The 3-phase input class listed on this part is the standard ABB EU/Asia industrial feed; line reactors, EMC filters, and dV/dt output filters are normally added based on motor cable length rather than as part of this order string.
