Its interrupting capacity at 240 V reaches 220 kA, dropping to 154 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — figures that tell you the available fault current this breaker can safely clear without upstream coordination failure. The 125 A rating holds up to 50 °C ambient (–); above that, the thermal curve begins a gradual derate — 120 A at 55 °C, 117.5 A at 60 °C, 115 A at 65 °C, 112.5 A at 70 °C (–). If your panel internal ambient exceeds 50 °C, the effective continuous capacity drops, so size the upstream feeder and bus accordingly. The TM240 release is a fixed thermal-magnetic design — no electronic adjustment, no communication, no ground-fault module. That keeps the part simple and reliable for straightforward line-protection duty where you don't need selective coordination curves or remote monitoring. That's useful for a PLC or SCADA input that distinguishes a manual open from a fault.","metaTitle":"3VA1112-6EF32-0AF0 SENTRON MCCB, 125 A, 220 kA at 240 V","metaDescription":"SENTRON 3VA1112-6EF32-0AF0 molded case circuit breaker, 125 A continuous, 220 kA breaking at 240 V, TM240 release, active production, available to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Molded Case Circuit Breakers (MCCB)"],"specifications":{"Depth":"70 mm","Width":"76.2 mm","Height":"130 mm","at 240 V":"220 kA","at 415 V":"154 kA","at 440 V":"75.6 kA","at 690 V":"17 kA","at 40 °C":"125 A","at 45 °C":"125 A","at 50 °C":"125 A","at 55 °C":"120 A","at 60 °C":"117.5 A","at 65 °C":"115 A","at 70 °C":"112.5 A","Trip indicator":"Yes","Number of poles":"3","Product version":"Line protection","Voltage trigger":"No","lifecycle_stage":"current","Product brand name":"SENTRON","Product designation":"Molded case circuit breaker","Latching - endurance":"15 000","Undervoltage Release":"No","Communication Function":"No","Phase failure detection":"No","During Storage / Maximum":"80 °C","During Storage / Minimum":"-40 °C","Auxiliary contact version":"1 auxiliary switch + 1 trip alarm switch HQ","During Operation / Maximum":"70 °C","During Operation / Minimum":"-25 °C","Other Measurement Function":"No","Rated continuous current Iu":"125 A","Rated insulation voltage Ui":"800 V","Design of the auxiliary release":"without auxiliaryrelease","Ground fault monitoring version":"Without","Design of the overcurrent release":"TM240","Design of short-circuit protection":"For switching power values in DC networks, see the 3VA molded case circuit breaker device manual; link to be found under Service & Support in the last chapter","Protection class IP / on the front":"IP40","Reference code / acc. to DIN EN 81346-2":"Q","Adjustable response value time / tr max.":"1","Adjustable response value time / tr min.":"1","Max. rated operational voltage Ue with DC":"500 V","Undervoltage Release With Leading Contact":"No","Product extension / optional / motor drive":"Yes","Adjustable response value current / Ir max.":"125 A","Adjustable response value current / li max.":"1 250 A","Adjustable response value current / li min.":"625 A","Adjustable response value current / lr min.":"88 A","Neutral conductors / upgradeable/retrofittable":"No","Number of CO contacts / for auxiliary contacts":"2","Protective function of the overcurrent release":"LI","Of The Integrated Auxiliary Switch/Alarm Switch":"3VA9988-0AB12","Switching capacity class of the circuit breaker":"H","Max. rated operational current of the frame size":"160 A","Max. rated operational voltage Ue with AC 50/60Hz":"690 V","Type of electrical connection / for main current circuit":"lug terminal","Arrangement of electrical connectors / for main current circuit":"Front terminal","Type of connectable conductor cross-section, connection screw, width x thickness , max.":"17 x 6.5","Type of connectable conductor cross-section, connection screw, width x thickness , min.":"12 x 0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=486202&mlfb=3VA1112-6EF32-0AF0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA1112-6EF32-0AF0/alternatives.json"},"ai":{"faq":[{"question":"What is the breaking capacity of 3VA1112-6EF32-0AF0 at different voltages?","answer":"The breaking capacity is 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V (–)."},{"question":"Where can I buy 3VA1112-6EF32-0AF0 and how is it quoted?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1112-6EF32-0AF0","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/3VA1112-6EF32-0AF0 when reusing this data.
