That 220 kA figure at 240 V means this breaker can safely interrupt a fault current up to 220,000 A without welding its contacts or rupturing the case — critical for high-fault installations like transformer secondaries or large motor control centers where the available fault current is well above what a standard 65 kA or 100 kA MCCB could handle. Above that it drops: 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, 114 A at 70 °C.","metaTitle":"Siemens 3VA1112-6EF36-0KA0 SENTRON MCCB, 125 A, 3-Pole, 220","metaDescription":"Siemens 3VA1112-6EF36-0KA0 SENTRON molded case circuit breaker, 125 A rated at 40 °C, 3-pole, TM240 release, 220 kA breaking at 240 V.

The part is sourced through independent distribution channels; availability and current pricing are confirmed at quote time — no stock count or price figure is published here."},{"question":"What is 3VA1112-6EF36-0KA0's breaking capacity at 240 V?","answer":"220 kA at 240 V AC. That's the highest interrupting rating in this breaker's voltage curve — it clears faults up to 220,000 A at that level without failing."},{"question":"Will 3VA1112-6EF36-0KA0 drop into a panel specified around 3VA1112-5EE32-0AA0 without rewiring?","answer":"Both are 3-pole SENTRON 3VA frame breakers with the same 130 mm height, 76.2 mm width, and 70 mm depth footprint, so the mechanical fit is identical. The electrical difference is the release: this one carries a TM240 thermal-magnetic release rated 125 A, while the 5EE32 variant uses a different trip unit — verify the load current and coordination study before swapping, but the panel cutout and bus connections are the same."},{"question":"What compliance documentation does this brand provide for 3VA1112-6EF36-0KA0?","answer":"Siemens SENTRON 3VA breakers carry UL, CSA, IEC, and CCC certifications as standard for the series. RoHS and REACH compliance declarations are available through Siemens' documentation portal. Specific certs for this order code should be confirmed on the manufacturer's certificate download page."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1112-6EF36-0KA0","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/3VA1112-6EF36-0KA0 when reusing this data.
