This MCCB delivers 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V (–). The TM240 release provides thermal and magnetic trip curves matched to cable and transformer protection. ## Current derating and thermal budget Above 50 °C it derates: 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, 114 A at 70 °C (–). Maximum power loss is 28.1 W — factor that into enclosure ventilation, especially when grouping multiple breakers. ## Built-in auxiliary switching and trip indication Factory-fitted with 1 auxiliary switch and 1 trip alarm switch — no separate order for signal contacts. The trip indicator gives local visual status.","metaTitle":"3VA1112-5EF36-0AG0 SENTRON MCCB, 125 A, 3-Pole, TM240","metaDescription":"Siemens SENTRON 3VA1112-5EF36-0AG0 molded case circuit breaker, 125 A at 40 °C, 3-pole, TM240 release, 187 kA at 240 V.

Submit an RFQ for volume pricing and lead-time confirmation — availability and price are confirmed at quote time, not listed publicly."},{"question":"What is 3VA1112-5EF36-0AG0's listed depth?","answer":"The depth is 70 mm (2.76 in). Combined with the 76.2 mm width and 130 mm height, it fits standard MCCB panel cutouts and DIN-rail adapter plates."},{"question":"Will 3VA1112-5EF36-0AG0 drop into a panel specified around 3VA1110-5ED36-0AC0 without rewiring?","answer":"Both are 3-pole SENTRON MCCBs in the same 3VA1 frame size with identical 70 mm depth, 76.2 mm width, and 130 mm height. The 3VA1112-5EF36-0AG0 carries a higher 125 A rating versus the 3VA1110-5ED36-0AC0's lower ampacity, so the panel bus and cable must be sized for 125 A. Mechanical fit is the same; wiring terminals are in the same positions."},{"question":"What compliance documentation does Siemens provide for 3VA1112-5EF36-0AG0?","answer":"As a SENTRON MCCB, Siemens typically supplies RoHS and REACH declarations, plus IEC/EN 60947-2 certification. Specific UL/CSA file numbers and CE/UKCA declarations are available on request with the order. The 800 V rated insulation voltage aligns with IEC 60947-2 insulation coordination requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1112-5EF36-0AG0","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/3VA1112-5EF36-0AG0 when reusing this data.
