Both are ACS550-U1 frame drives, but the -09A0-6 is a 6 A variant at a different voltage class (likely 600 V class). They are not drop-in replacements without verifying voltage and current ratings for the specific motor load."},{"question":"Will the ACS550-U1-038A-4+B055 drop into a panel specified around the ACS550-U1-09A0-6 without rewiring?","answer":"Not without verification. Both share the ACS550-U1 frame, so the mechanical footprint and gland-plate layout are likely identical. However, the -038A-4 is a 38 A, 400 V class unit, while the -09A0-6 is a 6 A, 600 V class unit. Power wiring, fusing, and motor cable sizing differ. Always compare the nameplate ratings before swapping."},{"question":"What compliance documentation does ABB provide for this drive?","answer":"The evidence does not list specific compliance documentation (RoHS, REACH, UL, IEC) for this order code. Standard ABB ACS550-series drives typically carry CE and cULus marks, but confirm with the supplier at RFQ time."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/abb/ACS550-U1-038A-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-U1-038A-4~3B055 when reusing this data.
