The key difference is the release: the 3VA1125-3ED26-0AA0 uses a TM210 thermal-magnetic release with fixed instantaneous at 320 A, while the 3VA1020-3ED36-0AA0 uses a different release variant. Check the release curve and the 25 A vs lower current rating before swapping — the panel cutout and wiring space are the same."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1125-3ED26-0AA0","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/3VA1125-3ED26-0AA0 when reusing this data.
