What the code resolves to
The ABB ACS800-U4-0260-5+E208+E210+P901 is an ACS800-series wall-mount low-voltage drive ordered with the +E208, +E210, and +P901 option codes bundled into the part string, which is how ABB identifies the as-built configuration on the rating plate and in the shipping documents. It sits in the Motor Drives subcategory under ABB's Drives portfolio, so the BOM line is read as a motor-side power converter rather than a soft-starter or standalone controller. Mass on the listing is 99.79 kgs, which puts the unit firmly in cabinet-floor territory — plan a lifting aid and confirm the cabinet base or wall-bracket is rated for that service load before the drive is set in place.
Frame and handling reality
The ACS550-U1-157A-4 sits at 89.81 kgs in the same peer set, so a buyer weighing a value-engineered spare needs to read that as a frame-class difference inside ABB's drive range, not as a drop-in for an ACS800-U4 build.
Configured options, not generic
The +E208, +E210, and +P901 suffix codes are part of the order code itself, which means any replacement or spare has to be specified with the same suffix set to land as a like-for-like unit — quoting the bare ACS800-U4-0260-5 base code will not preserve the as-built behavior. Because the options ride inside the MPN string, the drive's commissioning parameter set, control-terminal population, and any application macro are tied to this exact code; the panel builder wires to the drawing that names the full suffix, not to a generic ACS800 manual.
Sourcing posture
Buyers evaluating a second-source or successor should weigh the ACS880-01-156A-5 against it deliberately — different frame, different mass, different control firmware — rather than treating any peer code as a like-for-like spare for an installed ACS800-U4 panel.
