If your panel runs hot, the actual ampacity is lower than the nameplate; plan the load accordingly. At 240 V it handles 76 kA; at 415 V, 53 kA; at 440 V, 32 kA; at 500 V, 12 kA. The 415 V figure (53 kA) is the one most relevant for 400 V industrial distribution in Europe and Asia. The overcurrent release is a TM220 thermal-magnetic type, so it provides both thermal (overload) and magnetic (short-circuit) protection in one unit. Maximum power loss is 23 W, so plan for that heat dissipation inside the enclosure; if you pack multiple breakers side by side, the internal temperature rise may push you into the derated current column above 55 °C. If you need remote tripping or ground-fault sensing, you'd step up to a 3VA-series or add external accessories. The trip indicator is not present, so visual trip status is read from the handle position only.","metaTitle":"Siemens 3VM1112-3EE32-0AA0 SENTRON MCCB, 125 A, 76 kA at 240","metaDescription":"Siemens SENTRON 3VM1112-3EE32-0AA0 molded case circuit breaker, 3-pole, 125 A rated at 40 °C, 76 kA breaking capacity at 240 V.

The key difference: the 3VA series typically offers higher breaking capacities and optional accessories (shunt trip, UVR, communication) that the 3VM lacks. If your panel needs those features, the 3VA is the upgrade path. If you only need a plain thermal-magnetic line protection breaker, the 3VM is the cost-optimized fit. Both are 3-pole, but verify the mounting footprint — the 3VA frame may be slightly larger."},{"question":"Will 3VM1112-3EE32-0AA0 drop into a panel specified around 3VA1020-2ED32-0DD0 without rewiring?","answer":"Not necessarily. While both are 3-pole Siemens MCCBs, the 3VM1112-3EE32-0AA0 has a 76.2 mm width and 70 mm depth, whereas the 3VA1020-2ED32-0DD0 may use a different frame depth and terminal arrangement. You would need to compare the terminal centers and mounting hole pattern from the respective datasheets before assuming a direct swap."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VM1112-3EE32-0AA0","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/3VM1112-3EE32-0AA0 when reusing this data.
