What this order code actually buys
The ABB ACS800-01-0255-5+D150+K454+L502+L508+N803+P901 is a fully configured ACS800-01 wall-mount AC drive — the base frame is the 0255-5 rating class, and the six plus-codes (+D150, +K454, +L502, +L508, +N803, +P901) lock in the control board, I/O, fieldbus, braking and enclosure choices that the panel-builder specified when the line was built. It sits in ABB's industrial drives line under the Motors & Motor Controls category, classified as a Motor Drive. For a procurement line that names every plus-code, only a like-for-like configured unit satisfies the spec; a bare ACS800-01-0255-5 chassis without +D150 / +K454 / +L502 / +L508 / +N803 / +P901 will not match the as-built control, feedback or fieldbus wiring even if the frame rating aligns.
Handling, panel reinforcement and the install site
Listed weight is 127.01 kgs, which means the cabinet base or wall-mount bracket has to be sized for a true three-figure kilogram load — a single-person lift is out of the question and the pallet-in / hoist-in path drives the install sequence. That mass is also the first clue that the unit was specified for a heavy-industrial cell: hot-strip mill stands, coiler sections, large fan or pump MCC rooms — anywhere the drive enclosure sits next to a multi-kilowatt motor and where cabinet cooling has to be designed around the converter's own waste heat.
Sourcing posture for the configured build
A configured order code of this length almost always means the unit has to be matched against the as-built plus-code string — quoted to order against the buyer's RFQ rather than pulled from a generic shelf, because the wrong option slot (a different +D150 variant, a different +N803 firmware region, a missing +P901) is what causes the dreaded 'powers up but won't talk to the line' commissioning miss. Sourcing the exact configured string is the lever that protects the install schedule; a frame-compatible chassis in the wrong configuration is the classic line-down trap on ACS800 retrofits, especially where the original panel drawings name the plus-codes explicitly. Send the full configured string — base code plus every plus-code, in the order ABB prints them — on the RFQ so the quotation matches the nameplate the cell was built around.
