The +K451 suffix adds the RDNA-01 DeviceNet adapter as the fieldbus slice, and +L502 layers in the pulse encoder interface option for closed-loop speed feedback — both are factory-installed suffixes, not field-retrofittable modules, so they have to be on the PO. ## US panel and NEMA framing The -U1- construction code on this build is the US installation and NEMA-compliance variant, which is the right pick when the drive is being specified into a NEMA-style US panel rather than the IEC-default frame, and it is what makes the +K451/+L502 option suffix set legitimate for a North American build. ## Handling and cabinet fit The drive ships at 21.32 kg, which puts it in the bracket where the unit needs a two-person lift or a panel-side mounting aid rather than a benchtop swap, and it should be planned around that mass in the cabinet layout and any rigging step. ## Where it sits against the next-frame sibling The ACS550-U1-059A-4+B055 sibling holds the 059A current code but reworks the enclosure to the +B055 option, which is a different mechanical build rather than a true cross-reference — the electrical rating carries, but the cabinet cut-out and conduit entry change, so it does not drop in for the +K451+L502 build without a mechanical re-spec.","metaTitle":"ABB ACS550-U1-059A-4+K451+L502 Drive, 59 A, 30 kW","metaDescription":"ABB ACS550-U1-059A-4+K451+L502 ACS550 drive, 380-480 VAC three-phase output at 59 A (30 kW), with RDNA-01 DeviceNet and pulse encoder interface options, NEMA-compliant US build, qu","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["AC Drive (VFD) 480V"],"specifications":{"Part #":"ACS550-U1-059A-4+K451+L502","Weight":"21.32 kgs","Category":"Drives","Option 1":"RDNA-01 DeviceNet","Option 2":"Pulse encoder interface","Construction":"US Installation and NEMA Compliance","Sub Category":"Motor Drives","Top Category":"Motors & Motor Controls","lifecycle_stage":"eol_hot","Output Current Rating":"Three-Phase, 380-480 VAC, 50/60 HZ, 59 A, 30 KW"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7,417.69","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/ACS550-U1-059A-4%2BK451%2BL502/alternatives.json"},"ai":{"faq":[{"question":"What is the ABB ACS550-U1-059A-4+K451+L502's listed part number on this Motor Drives line?","answer":"The part number is ACS550-U1-059A-4+K451+L502, with +K451 adding the RDNA-01 DeviceNet adapter and +L502 adding the pulse encoder interface option on the standard ACS550-U1-4 platform."},{"question":"Will the ACS550-U1-059A-4+K451+L502 drop into a panel that was specified around the ACS550-U1-096A-4?","answer":"Both sit on the ACS550-U1-4 wall-mount platform, so the option-bus slot, mounting footprint, and wiring layout carry over — the change is the current code (059 A vs 096 A), which is a motor-fit decision rather than a panel-rewire decision."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/abb/ACS550-U1-059A-4~3K451~3L502","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-U1-059A-4~3K451~3L502 when reusing this data.
