Front IP40 protection means the breaker face is sealed against tools and solid objects >1 mm, but the rear terminals are open to the enclosure — plan for a dead-front panel or terminal shrouds. ## Sourcing and production status Maximum power loss is 28.1 W at rated load — account for this in the enclosure thermal budget, especially in a multi-breaker panel with limited ventilation.","metaTitle":"Siemens 3VA1112-4EE36-0AA0 MCCB, 125 A, 121 kA at 240 V","metaDescription":"Siemens SENTRON 3VA1112-4EE36-0AA0 molded case circuit breaker, 3-pole, 125 A rated at 40 °C, 121 kA breaking capacity at 240 V.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Molded Case Circuit Breakers (MCCB)"],"specifications":{"Depth":"70 mm","Width":"76.2 mm","title":"3VA1112-4EE36-0AA0","Height":"130 mm","Maximum":"0 A","Minimum":"0 A","at 240 V":"121 kA","at 415 V":"75.6 kA","at 440 V":"52.5 kA","at 500 V":"11.9 kA","at 690 V":"11.9 kA","at 40 °C":"125 A","at 45 °C":"125 A","at 50 °C":"125 A","at 55 °C":"122 A","at 60 °C":"120 A","at 65 °C":"117 A","at 70 °C":"114 A","Depth [In]":"2.76 in","Width [In]":"3 in","Height [In]":"5.12 in","description":"circuit breaker 3VA1 IEC frame 160 breaking capacity class S Icu=36kA @ 415V 3-pole, line protection TM220, ATFM, In=125A overload protection Ir=88A...125A short-circuit protection Ii=10 x In clamp connection","Trip Indicator":"No","Number Of Poles":"3","Voltage Trigger":"No","lifecycle_stage":"current","Product Brand Name":"SENTRON","Product Designation":"Molded case circuit breaker","Undervoltage Release":"No","Design Of The Product":"Line protection","Communication Function":"No","During Storage / Maximum":"80 °C","During Storage / Minimum":"-40 °C","power loss [W] / maximum":"28.1 W","During Operation / Maximum":"70 °C","During Operation / Minimum":"-25 °C","Other Measurement Function":"No","Ground-Fault Monitoring Version":"Without","Insulation Voltage / Rated Value":"800 V","Design Of The Overcurrent Release":"TM220","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","Product Function / Grounding Protection":"No","operating voltage / at AC / rated value":"690 V","operating voltage / at DC / rated value":"500 V","reference code / according to IEC 81346-2":"Q","Product Extension / Optional / Motor Drive":"Yes","Protection Function Of The Overcurrent Release":"LI","number of CO contacts / for auxiliary contacts":"0","Switching Capacity Class Of The Circuit Breaker":"S","Mechanical Service Life (Operating Cycles) / Typical":"20 000","Type Of Electrical Connection / For Main Current Circuit":"box terminal on both sides","Arrangement Of Electrical Connectors / For Main Current Circuit":"Front terminal"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$207.01","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/21e9d4a9459d08e9425644ba5088b688.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=376424&mlfb=3VA1112-4EE36-0AA0"},"ai":{"faq":[{"question":"Is 3VA1112-4EE36-0AA0 obsolete or active?","answer":"The lifecycle stage is current — this is an active-production part from the Siemens SENTRON 3VA1 series."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1112-4EE36-0AA0","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/3VA1112-4EE36-0AA0 when reusing this data.
