What you're sourcing
The ABB ACS800-01-0005-5+B056+N652+P901 is an ACS800-01 frame-size wall-mount drive carrying three factory-fit option codes — +B056, +N652 and +P901 — that have to match the BOM line exactly, because a stripped or rebuilt option string on a replacement unit will not behave the same in the panel. Listed unit weight is 13.61 kgs, which is the figure to plan around for the lift, the cabinet mounting plate and the shipping crate — not a paper spec, it drives what one tech can carry versus what needs a second pair of hands on the unbox. It lives on the ABB ACS800-01 wall-mount platform, the predecessor generation to the current ACS880-01 line, which is the context that decides whether you treat this as an active spec or as a long-tail spare that has to go through the broker channel.
On the option codes and what they imply
The +B056, +N652 and +P901 suffixes are ABB factory option codes appended to the base ACS800-01-0005-5 catalog number; the suffix string travels with the serial plate and is what the commissioning engineer keys off when loading the matching firmware macro, so a replacement drive ordered without the same option string lands on site as the wrong configuration.
Sourcing posture
Sourcing comes through the ABB ACS800 product line — quote to order against an RFQ so the option string is verified against the serial-plate record before the unit ships, rather than substituted with a generic ACS800-01-0005-5 body.
