That derating curve is the real-world limit for a warm panel; if your enclosure ambient sits at 55°C, you're buying a 375 A breaker, not 400 A. Interrupting capacity is the headline: 242 kA at 240 V, dropping to 187 kA at 415 V and 440 V, then 121 kA at 500 V, and 7.5 kA at 690 V. That 242 kA figure at 240 V covers high-fault service-entrance applications; the steep drop to 7.5 kA at 690 V means this is not a 690 V main breaker for high-fault industrial grids — it's sized for 480 V or 600 V class systems where the available fault current stays under 121 kA. No ground-fault monitoring is included; if GF protection is needed, that's an external module or a different variant. ## Panel fit and mounting — 110 mm depth matters The MCCB measures 110 mm deep by 138 mm wide by 248 mm high. The 138 mm width for a 3-pole frame is standard for SENTRON 3VA2 fixed breakers; verify that the existing busbar or cable lug kit matches the line-side terminal centers before committing the panel layout. ## Auxiliaries and communication — what's built in The breaker includes a communication function — the 3VA2 platform supports optional communication modules (PROFIBUS, PROFINET, Modbus) for power monitoring and remote trip indication. The base unit ships with two HQ auxiliary switches and an undervoltage release. The trip indicator is not present on this variant, so no local mechanical flag for trip cause — that data comes through the communication interface or the aux switches.","metaTitle":"Siemens 3VA2340-6JP32-0CC0 SENTRON MCCB, 400 A, 242 kA","metaDescription":"Siemens SENTRON 3VA2340-6JP32-0CC0 molded case circuit breaker, 400 A continuous at 40°C, 242 kA SCCR at 240 V. 3-pole, line protection, with undervoltage release and 2 aux switche","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Molded Case Circuit Breakers (MCCB)"],"specifications":{"Depth":"110 mm","Width":"138 mm","Height":"248 mm","Maximum":"4 000 A","Minimum":"600 A","at 240 V":"242 kA","at 415 V":"187 kA","at 440 V":"187 kA","at 500 V":"121 kA","at 690 V":"7.5 kA","at 40 °C":"400 A","at 45 °C":"400 A","at 50 °C":"400 A","at 55 °C":"375 A","at 60 °C":"350 A","at 65 °C":"325 A","at 70 °C":"300 A","Depth [In]":"4.33 in","Width [In]":"5.43 in","Height [In]":"9.76 in","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":"Yes","Design Of The Product":"Line protection","Communication Function":"Yes","During Storage / Maximum":"80 °C","During Storage / Minimum":"-40 °C","power loss [W] / maximum":"98.5 W","During Operation / Maximum":"70 °C","During Operation / Minimum":"-25 °C","Other Measurement Function":"No","Of The Supplied Basic Switch":"3VA2340-6JP32-0AA0","Design Of The Auxiliary Switch":"2 auxiliary switches HQ","Design Of The Auxiliary Release":"undervoltage release (UVR)","Ground-Fault Monitoring Version":"Without","Continuous Current / Rated Value":"400 A","Insulation Voltage / Rated Value":"800 V","Design Of The Overcurrent Release":"ETU550","protection class IP / on the front":"IP40","design of the N-conductor protection":"adjustable OFF; 20% to 160%","Of The Integrated Auxiliary Trip Unit":"3VA9608-0BB24","Product Function / Grounding Protection":"No","operating voltage / at AC / rated value":"690 V","reference code / according to IEC 81346-2":"Q","Continuous Current / Rated Value / Maximum":"400 A","Product Extension / Optional / Motor Drive":"Yes","Protection Function Of The Overcurrent Release":"LSI","number of CO contacts / for auxiliary contacts":"2","Of The Integrated Auxiliary Switch/Alarm Switch":"3VA9988-0AA12","Switching Capacity Class Of The Circuit Breaker":"H","Mechanical Service Life (Operating Cycles) / Typical":"20 000","Type Of Electrical Connection / For Main Current Circuit":"on both sides nut keeper kit","Arrangement Of Electrical Connectors / For Main Current Circuit":"Front terminal"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/c1b3b6c5f6d67465025ac41848ceb75e.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=499481&mlfb=3VA2340-6JP32-0CC0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA2340-6JP32-0CC0/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 3VA2340-6JP32-0CC0 and how do I get a price?","answer":"This breaker is sourced to order against an RFQ through independent distribution. Submit an RFQ for current availability and pricing — confirmed at quote time, with no minimum order quantity constraints typical for this class of MCCB."},{"question":"When sourcing 3VA2340-6JP32-0CC0, what's the closest functional second-source — 3VA2116-5JP32-0AE0?","answer":"The 3VA2116-5JP32-0AE0 is a smaller-frame SENTRON MCCB rated for lower continuous current — it will not drop in as a direct replacement for the 400 A 3VA2340-6JP32-0CC0 without rewiring and re-evaluating the fault-current withstand. The 3VA2116 frame is physically smaller and has different terminal centers and a lower interrupting rating. For a functional equivalent at 400 A, stay within the 3VA2 fixed-frame family with matching pole count and accessories."},{"question":"What is 3VA2340-6JP32-0CC0's listed depth (110 mm) on this component line?","answer":"The depth is 110 mm. That is the dimension from the mounting surface to the front of the breaker — critical for enclosure depth selection. A 200 mm deep enclosure leaves 90 mm for wiring and bending radius behind the breaker."},{"question":"What is 3VA2340-6JP32-0CC0's listed width (138 mm) on this component line?","answer":"The width is 138 mm for the 3-pole frame. This is standard for the SENTRON 3VA2 fixed breaker family at this rating — verify that existing busbar or cable lug kits match the line-side terminal centers before panel layout."},{"question":"Will 3VA2340-6JP32-0CC0 drop into a panel that was specified around 3VA2116-5JP32-0AE0 without rewiring?","answer":"No. The 3VA2116-5JP32-0AE0 is a smaller-frame breaker with different terminal centers, a lower continuous current rating, and a different physical footprint. Dropping in the 400 A 3VA2340-6JP32-0CC0 would require rewiring the line and load connections, re-evaluating the busbar or cable sizing for 400 A, and confirming the enclosure has the depth (110 mm) and width (138 mm) to accommodate the larger frame."},{"question":"What compliance documentation does this brand provide for 3VA2340-6JP32-0CC0 (RoHS, REACH, UL, IEC)?","answer":"As a Siemens SENTRON product, this MCCB carries the standard compliance documentation for industrial circuit breakers — RoHS and REACH declarations, UL 489 listing, and IEC 60947-2 certification. The specific declaration numbers and certificates are available with the product documentation upon request through the RFQ process."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA2340-6JP32-0CC0","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/3VA2340-6JP32-0CC0 when reusing this data.
