That means in a 50 °C panel ambient — common in enclosed switchgear — you still get the full 200 A; above that, the thermal curve governs the actual ampacity. The interrupting ratings are 76 kA at 240 V AC, 53 kA at 415 V AC, 32 kA at 440 V AC, and 12 kA at 500 V AC. For a 415 V distribution board, the 53 kA figure gives solid headroom against most utility fault levels. Maximum power loss is 42 W — relevant for thermal coordination inside a sealed enclosure. Front protection is IP40, so tools or fingers won't contact live parts, but the body is not sealed against moisture ingress. Dimensions are 105 mm wide, 158 mm high, 70 mm deep.","metaTitle":"Siemens 3VM1220-3EE32-0AA0 SENTRON MCCB, 200 A, 3-Pole, TM22","metaDescription":"Siemens SENTRON 3VM1220-3EE32-0AA0 molded case circuit breaker, 200 A at 40 °C, 3-pole, TM220 release, 76 kA at 240 V.

Availability and current pricing are confirmed at quote time — submit an RFQ for a firm lead time and price."},{"question":"What is the closest functional second-source to 3VM1220-3EE32-0AA0?","answer":"The 3VA1112-5EE32-0AA0 is the closest functional peer in the SENTRON family. Both are 3-pole MCCBs with thermal-magnetic releases, but the 3VA series supports electronic trip units and communication modules. The 3VM is the line-protection economy variant."},{"question":"Will 3VM1220-3EE32-0AA0 drop into a panel specified around 3VA1112-5EE32-0AA0?","answer":"Both are 3-pole MCCBs in the same frame class, so the 105 mm width and mounting hole pattern are identical. The 3VM is shallower at 70 mm depth versus the 3VA's typical 80 mm, so it fits the same panel footprint without rewiring. Verify busbar connection orientation — the line/load lug positions are the same."},{"question":"What compliance documentation does Siemens provide for 3VM1220-3EE32-0AA0?","answer":"As a SENTRON MCCB, it carries CE marking for the European market and is designed to meet IEC 60947-2. UL and CSA listings are standard for the series; specific certification marks are confirmed on the nameplate. RoHS and REACH declarations are available from Siemens' documentation portal."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VM1220-3EE32-0AA0","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/3VM1220-3EE32-0AA0 when reusing this data.
