Insulation voltage is rated 800 V, so it's comfortable on 480Y/277 V or 400 V systems with headroom. Breaking capacity varies by system voltage: 53 kA at 240 V AC, 32 kA at 415 V, 14 kA at 440 V, and 8 kA at 500 V. That 32 kA at 415 V is the number most panel builders will check first for common 400 V industrial feeds — it tells you this breaker can interrupt a bolted fault on a 400 A transformer secondary without upstream fuses needing to clear first. The 40 A rating holds from 40 °C through 50 °C. At 55 °C it derates to 39 A, at 65 °C to 38 A, at 70 °C to 37 A. Power loss at rated load is 14 W — negligible for ventilation planning in a standard sheet-metal panel, but worth noting if you're packing six of these side by side. Dimensions are 76.2 mm wide (3 inches), 130 mm tall, 70 mm deep. That 3-inch width is the standard 3-pole MCCB footprint for this class — it occupies three 25 mm module positions on a DIN rail. IP40 on the front means tools and fingers are kept out, but it's not sealed against hose-down; keep it inside the enclosure.","metaTitle":"Siemens 3VM1040-2ED32-0AA0 SENTRON MCCB, 40 A, 3-Pole, TM210","metaDescription":"Siemens SENTRON 3VM1040-2ED32-0AA0 molded case circuit breaker, 40 A rated at 40°C, 3-pole, TM210 release.

The 3VM1040 is the economy line-protection choice; the 3VA adds adjustable trip curves and communication options. Footprint and mounting are similar, but the release behavior differs — verify coordination before swapping."},{"question":"What compliance documentation does this breaker carry?","answer":"As a Siemens SENTRON MCCB, it carries CE marking for the European market and is designed to IEC 60947-2. UL and CSA listings are standard for the SENTRON family, though specific file numbers should be confirmed per the factory certificate for your jurisdiction."},{"question":"Will 3VM1040-2ED32-0AA0 drop into a panel specified for 3VA1110-5ED32-0AA0 without rewiring?","answer":"Physical dimensions are the same 3-inch width and similar depth, so it fits the same DIN-rail footprint and bus-bar spacing. The 3VM lacks the electronic trip unit and communication interface of the 3VA, so no auxiliary wiring changes are needed — but the trip curve is fixed thermal-magnetic, not adjustable, so the protective coordination study must be rechecked."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VM1040-2ED32-0AA0","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/3VM1040-2ED32-0AA0 when reusing this data.
