The plus-B055 suffix is a factory option code bundled at order entry; it is part of the exact MPN, not a separate accessory. At 3.97 kgs it is a wall-mount format drive, not a DIN-rail module — handle and panel-cut decisions follow from that mass class, and the figure is the one to use on a panel layout drawing. ## Panel fit, mounting, and the 3.97 kgs number A 3.97 kgs drive goes on the back panel with standard fixings, not on a DIN rail; the mass is below the threshold where a single installer needs a second pair of hands, but it is heavy enough that the mounting surface and the four corner fasteners should be sized for a drive of this class rather than treated as a light component. For panel layout, the weight number is the one that drives enclosure loading and shipping-carton mass calculations, while the current/frame class is what drives the cut-out and gland-plate sizing.","metaTitle":"ABB ACS550-01-012A-4+B055 Motor Drive, 3.97 kgs","metaDescription":"ABB ACS550-01-012A-4+B055 ACS550 series motor drive, 3.97 kgs, sourced to order against an RFQ for replacement and panel-fit work.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["AC Drives (VFD)"],"specifications":{"Part #":"ACS550-01-012A-4+B055","Weight":"3.97 kgs","Category":"Drives","Sub Category":"Motor Drives","Top Category":"Motors & Motor Controls","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3,048.00","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/ACS550-01-012A-4%2BB055/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/abb/ACS550-01-012A-4~3B055","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/ACS550-01-012A-4~3B055 when reusing this data.
