Both are 3-pole, 250 A MCCBs with similar breaking capacities. The main difference is in the trip-unit variant — the -4JQ32-0AA0 is a line-protection version, while the -5JQ32-0AK0 carries a different trip-unit designation. Verify the trip-unit characteristics match your coordination study before substituting."},{"question":"Will 3VA2225-4JQ32-0AA0 drop into a panel specified for 3VA2225-5JQ32-0AK0?","answer":"Yes, both share the same SENTRON 3VA2 frame dimensions (86 mm deep, 105 mm wide, 181 mm high), so the physical fit and busbar connections are identical. No rewiring is needed for the mounting footprint."},{"question":"What compliance documentation is available for 3VA2225-4JQ32-0AA0?","answer":"As a Siemens SENTRON MCCB, this breaker is designed to meet IEC 60947-2 and UL 489 standards. RoHS and REACH compliance documentation is available from Siemens. Specific certification marks (UL, CSA, CE) should be confirmed on the nameplate or through the manufacturer's declaration of conformity."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA2225-4JQ32-0AA0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3VA2225-4JQ32-0AA0 when reusing this data.
