Breaking capacity hits 187 kA at 240 V AC, 121 kA at 415 V, 76 kA at 440 V, and still 17 kA at 500 V — so it clears high-fault scenarios without cascading upstream, especially on 240 V distribution where the 187 kA figure covers virtually any industrial fault. ## Trip unit and thermal performance TM220 means a fixed thermal-magnetic release with no interchangeable rating plugs — what you see is what protects the feeder. The 40 A rating holds flat through 50 °C; at 55 °C it derates to 39 A, at 65 °C to 38 A, and at 70 °C to 37 A. Maximum power loss is 11 W, so heat rejection inside the enclosure stays manageable. The breaker measures 70 mm deep by 76.2 mm wide by 130 mm tall — a standard 3-pole MCCB footprint that drops into most SENTRON panelboards and DIN-rail adapters without re-drilling gland plates.","metaTitle":"Siemens 3VM1140-5EE32-0AA0 SENTRON MCCB, 40A 3-Pole, 187kA a","metaDescription":"Siemens 3VM1140-5EE32-0AA0 SENTRON molded case circuit breaker. 40A rated, 3-pole, TM220 release.

The 3VM1 is the line-protection version with a TM220 release; the 3VA series offers higher interrupting ratings and more accessory options. Both share the 3-pole, 40 A class footprint, but the 3VA carries a different trip-unit design and typically a higher breaking capacity at the same voltage points — verify the specific interrupting rating needed before substituting."},{"question":"What compliance documentation does this brand provide for 3VM1140-5EE32-0AA0?","answer":"Siemens SENTRON MCCBs carry the standard IEC 60947-2 certification for molded case circuit breakers.

For specific RoHS, REACH, or UL documentation, request the manufacturer's declaration of conformity with your RFQ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VM1140-5EE32-0AA0","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/3VM1140-5EE32-0AA0 when reusing this data.
