It sits squarely in the Motor Drives category, not a softstarter or a contactor, so the BOM row reads as a VFD swap, not a control-component change. The chassis comes in at 6.80 kg, which is a one-person lift but a real mass on a swing-out panel — the cabinet frame, not the drive itself, is what feels it. For a mill-floor retrofit that weight is comfortable; for a rooftop MCC it is fine, but plan the swing-out bracket for the long side, not the face. ## Where the ACS550 class actually runs The ACS550 has been ABB's workhorse general-purpose drive for HVAC, fan, pump, and light-conveyor duty — the kind of line where you want solid torque per amp, plain parameter sets, and a drive that does not need a fieldbus card to talk to the PLC. On a hot-strip mill the radiator side of the cabinet is where a part like this either takes the radiant heat off the reheating furnace or quietly drifts its IGBT junction temperatures into derating; the ACS550 chassis is rated for cabinet-side mounting with the standard airflow path, and the +B055 option typically maps to a documented add-on that has to be preserved in the substitution check.","metaTitle":"ABB ACS550-U1-06A1-6+B055 Drive, 6.80 kg","metaDescription":"ABB ACS550-U1-06A1-6+B055 general-purpose drive (ACS550 series, +B055 option), 6.80 kg, sourced to order against an RFQ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["AC Drives (VFD)"],"specifications":{"Part #":"ACS550-U1-06A1-6+B055","Weight":"6.80 kgs","Category":"Drives","Sub Category":"Motor Drives","Top Category":"Motors & Motor Controls","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3,608.76","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/ACS550-U1-06A1-6%2BB055/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/abb/ACS550-U1-06A1-6~3B055","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-U1-06A1-6~3B055 when reusing this data.
