At 1.14 kg the unit is wall- or panel-mountable by hand; no lifting plan or reinforced cabinet shelf is needed. Cable entry and cooling clearance still follow ABB's installation drawing, not the weight. ## Why the +J400 suffix matters on this build The +J400 option is part of the order code, not a field add-on. Different +J options change the control board and fieldbus interface, so the wrong suffix means a drive that powers up but cannot talk to the PLC on the existing wiring. Match the suffix letter-by-letter on the replacement BOM line. ## ACS380-040C-05A6-4+K475 as a cross-shop candidate The closest functional second-source from the same ABB catalogue is the ACS380-040C-05A6-4+K475. It is also a compact machine drive and sits at a near-identical mass of 1.13 kg, but the frame and option suffix differ. Treat it as an alternative for a new panel layout, not a guaranteed drop-in where an ACS355-03U-04A1-4+J400 is already wired in. ## Sourcing posture For a line-down replacement, send the full MPN including the +J400 suffix so the supply channel confirms the option matches before shipment.","metaTitle":"ABB ACS355-03U-04A1-4+J400 drive, 1.5 kW","metaDescription":"ABB ACS355-03U-04A1-4+J400 micro drive rated 1.5 kW, +J400 option code, 1.14 kg — sourced to order against an RFQ for compact machine applications.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["AC Drives (VFD)"],"specifications":{"Part #":"ACS355-03U-04A1-4+J400","Weight":"1.14 kgs","Category":"Drives","Sub Category":"Motor Drives","Top Category":"Motors & Motor Controls","lifecycle_stage":"current"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$924.42","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/ACS355-03U-04A1-4%2BJ400/alternatives.json"},"ai":{"faq":[{"question":"Is the ACS380-040C-05A6-4+K475 a direct drop-in replacement for an existing ACS355-03U-04A1-4+J400 panel?","answer":"No. The ACS380-040C-05A6-4+K475 is the same ABB micro-drive class at a comparable 1.13 kg, but the frame, current rating and option suffix differ.
