What it is, and what the +E200 means on the order code
The ABB ACS800-01-0003-3+E200 is the size-01 frame of the ACS800 series, a wall-mount single-drive AC drive that sits in the ABB low-voltage drives lineup alongside later-generation families. The frame is sized to be lifted onto the panel by one technician: the listed weight is 3.90 kg, which keeps mounting hardware to a standard stud size rather than the spreader-bar work a multi-module chassis demands. Like other order codes in the ACS800-01 line, the suffix string (the +E200 designator here) is the engineering placeholder that defines which control board, option pack, and language set ship on the unit, so two otherwise identical size-01 drives ordered under different suffixes are not field-swappable without re-checking the parameter map.
Where the ACS800-01 fits in an ABB drive bill of materials
The ACS800-01 is the wall-mount / cabinet-build form factor in the ACS800 family, used where the cabinet is built around the drive rather than the drive being supplied as a pre-engineered module. For sizing decisions, the listed mass of 3.90 kg sets the mechanical side of that choice: small enough that DIN-backplate or sub-panel mounting is routine, light enough that the cabinet does not need to be reinforced for the drive alone. Practically, drives of this frame are specified for fans, pumps, mixers, conveyors, and similar constant- or quadratic-torque loads where the application engineer wants ABB's DTC-style control option set but does not need the higher-current or liquid-cooled chassis.
Cross-shopping against the published ACS880 successor family
When an installed ACS800-01 is being replaced or duplicated, the natural cross-shop is the ACS880-01 frame that ABB positions as the successor generation; one ACS880-01-11A0-5 is listed at 4.54 kg, heavier than the 3.90 kg ACS800-01-0003-3+E200 on record, which is the mass delta a cabinet layout review should expect. A second ACS880-01 variant on the same ordering line, the ACS880-01-07A6-5 at 6.35 kg, sits well above the ACS800-01-0003-3+E200 on mass, signalling a larger current rating that would only be a fair cross-shop if the application is being re-sized rather than like-for-like replaced. The ACS580-01-031A-2, listed at 2.99 kg, is in the same general-purpose low-voltage tier but is a different product family rather than a functional cross-reference; it is worth showing in the catalog as a contemporary alternative, not as a swap for an installed ACS800-01-0003-3+E200.
Procurement posture for this order code
Specifying it into a BOM line should be done by quoting against the exact order string ACS800-01-0003-3+E200, including the +E200 suffix, so the control-option set that ships matches the panel drawing and parameter map.
