The U31 suffix marks the wall-mount IP21 form factor of the ACS800-U31 series. ## Handling and mounting footprint Listed mass is 29.48 kgs, a single-installer lift onto a reinforced backplate rather than a DIN-rail snap-on. Plan cabinet handling around a 29.48 kg chassis with cooling clearance top and bottom per the U31 frame. ## Where the U31 sits in the migration path The ACS800-U31 is the legacy predecessor to ABB's ACS880-01 wall-mount line, which is the family most new panels are specified against today. Buyers cross-shopping this code against the ACS880-01-040A-5 (18.14 kgs) or ACS880-01-065A-5 (23.13 kgs) are looking at the modern replacement frame; the U31 cannot be specified as a drop-in for an ACS880-01 panel because the mechanical footprint, control board layout and firmware toolchain differ between the two generations. ## RFQ and next step If the ACS800-U31-0040-5 is on the BOM as a like-for-like spare for an installed ACS800 cabinet, send the part number and quantity for a quoted lead; if it is being considered as a substitute for an ACS880-01-040A-5 or ACS880-01-065A-5 panel position, the engineering review has to come before the RFQ because the two frames are not mechanically interchangeable.","metaTitle":"ABB ACS800-U31-0040-5 AC Drive, 29.48 kg","metaDescription":"ABB ACS800-U31-0040-5 AC drive, wall-mount U31 frame at 29.48 kgs, sourced to order against an RFQ for legacy ACS800 line support.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["AC Drives (VFD)"],"specifications":{"Part #":"ACS800-U31-0040-5","Weight":"29.48 kgs","Category":"Drives","Sub Category":"Motor Drives","Top Category":"Motors & Motor Controls","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/ACS800-U31-0040-5/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second-source when sourcing the ACS800-U31-0040-5?","answer":"Within the same ABB wall-mount form factor, the ACS880-01-040A-5 sits closest to the U31-0040-5 current node and is the official modern replacement family; it is a different generation and is not a mechanical drop-in, so any cross-reference must go through engineering review before a panel redesign is committed."},{"question":"Will the ACS800-U31-0040-5 drop into a panel specified around the ACS880-01-065A-5 without rewiring?","answer":"No. The U31 and ACS880-01 frames differ in mechanical footprint, control board layout and firmware toolchain, so the U31 cannot be specified as a drop-in for an ACS880-01 cabinet position."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/abb/ACS800-U31-0040-5","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/abb/ACS800-U31-0040-5 when reusing this data.
