That thermal stability means you can load it near nameplate in a warm panel without forced derating. Interrupting capacity is rated per voltage: 76 kA at 240 V, 53 kA at 415 V, 32 kA at 440 V, and 12 kA at 500 V. The 76 kA at 240 V figure is the headline — it handles high-fault scenarios on 240 V distribution without cascading upstream. The 53 kA at 415 V covers the common three-phase industrial voltage. ## Form factor and panel fit Dimensions: 70 mm depth, 101.6 mm width, 130 mm height. Width at 101.6 mm (4 inches) is the standard 4-pole MCCB footprint; it occupies four 25 mm DIN spaces if mounted on a DIN rail adapter. Rated insulation voltage: 800 V. Overcurrent release design: TM220 (thermal-magnetic, fixed thermal and magnetic settings). Power loss at rated load: 15 W maximum. Storage temperature: -40 °C to 80 °C. Trip indicator is not present — visual trip indication is via the handle position only.","metaTitle":"Siemens SENTRON 3VM1150-3EE46-0AA2 MCCB, 4-Pole, 50 A, 76 kA","metaDescription":"Siemens SENTRON 3VM1150-3EE46-0AA2 molded case circuit breaker, 4-pole, 50 A rated at 40 °C, 76 kA interrupting at 240 V.

The delta is in the release design and interrupting ratings — the 3VA series uses a different trip unit platform (electronic vs TM220 thermal-magnetic). Verify the interrupting capacity at your system voltage and the trip curve before substituting; the 3VM series is the economy line, the 3VA series is the full-featured line with higher interrupting options and electronic trip units."},{"question":"Will 3VM1150-3EE46-0AA2 drop into a panel specified around 3VA1110-5ED36-0AC0 without rewiring?","answer":"Form factor is the same — both are 4-pole SENTRON MCCBs with the same 70 mm depth, 101.6 mm width, and 130 mm height. The mounting hole pattern and bus bar spacing are identical across the 3VM and 3VA families. No rewiring is needed for the same ampacity and pole count, but check the interrupting capacity at your fault level: the 3VA series typically offers higher kA ratings than the 3VM economy line."},{"question":"Where can I buy 3VM1150-3EE46-0AA2 and how is it quoted?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ with your target quantity and delivery window; we will confirm availability and current pricing at quote time. No minimum order quantity restrictions apply."},{"question":"What compliance documentation does Siemens provide for 3VM1150-3EE46-0AA2?","answer":"Siemens SENTRON MCCBs are typically supplied with CE marking, RoHS compliance, and IEC 60947-2 certification. The specific declarations and test reports are available from Siemens Industry Online Support under the 3VM product documentation. For UL/CSA listings, verify the specific variant — the 3VM series is primarily IEC-rated; the 3VA series carries UL 489 listing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VM1150-3EE46-0AA2","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/3VM1150-3EE46-0AA2 when reusing this data.
