What landed on the BOM line
The ABB ACS800-01-0020-3+E202+H358+L503 is the ACS800-01 wall-mount AC drive frame carrying the +E202, +H358 and +L503 option build under one combined code. It sits in the Motor Drives line inside the broader Drives family, and the unit weighs 14.06 kg.
Handling and panel fit
At 14.06 kg the drive sits in the bracket of wall-mount ACS800-01 units a single technician can shoulder into place on a prepared backplate, but it is heavy enough that the cabinet needs a real lift path — not a free rest on a gland plate. Because the +E202/+H358/+L503 options are factory-fitted, the cut-out and clearance around the drive should match the standard ACS800-01 outline; no extra panel real estate is consumed by separately mounted option boxes, which is the usual reason a buyer sourcing this code reaches for it over a base-unit-plus-field-kit build.
Where the ACS800 class sits in the line
The ACS800-01 is the compact wall-mount member of ABB's industrial AC-drive family, used to run standard induction motors in machinery and process cells where a cabinet-format drive would be over-specified. A sourcing buyer looking at this exact code is generally maintaining an installed base or filling a BOM line that was originally specified against the ACS800 platform rather than moving new construction to its successor.
Sourcing posture
The code carries a multi-option build (+E202, +H358, +L503) which is how ABB configures factory-fit variants on the ACS800-01 line; that is the order string a buyer quotes against the BOM, not a base catalog number with accessories added later. For sourcing, the right move is to specify this exact order code into the RFQ so the drive arrives with the option build already applied and the panel-builder wiring matches the original engineering pack.
