Maximum power loss is 66 W, so factor that into the enclosure thermal budget if grouping multiple breakers in a sealed cabinet.","metaTitle":"Siemens 3VA2440-5MN32-0BH0 SENTRON MCCB, 400 A, 3-Pole, Moto","metaDescription":"Siemens 3VA2440-5MN32-0BH0 SENTRON molded case circuit breaker, 400 A at 40 °C, 3-pole, motor protection design with phase failure detection and undervoltage release. 187 kA interr","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":"17 s","Minimum":"4 s","at 240 V":"187 kA","at 415 V":"121 kA","at 440 V":"121 kA","at 500 V":"75.6 kA","at 690 V":"9 kA","at 40 °C":"400 A","at 45 °C":"400 A","at 50 °C":"400 A","at 55 °C":"400 A","at 60 °C":"400 A","at 65 °C":"400 A","at 70 °C":"400 A","Depth [In]":"4.33 in","Width [In]":"5.43 in","Height [In]":"9.76 in","Limited To 1 S":"5 kA","Trip Indicator":"Yes","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":"Motor protection","Communication Function":"No","Phase Failure Detection":"Yes","During Storage / Maximum":"80 °C","During Storage / Minimum":"-40 °C","power loss [W] / maximum":"66 W","During Operation / Maximum":"70 °C","During Operation / Minimum":"-25 °C","Other Measurement Function":"No","Of The Supplied Basic Switch":"3VA2440-5MN32-0AA0","Design Of The Auxiliary Switch":"2 auxiliary switches + 1 trip alarm switch 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","adjustable trip class (Tc CLASS)":"10A, 10E, 20E","Design Of The Overcurrent Release":"ETU350M","protection class IP / on the front":"IP40","operating power / at AC-3 / at 230 V":"90 000 W","operating power / at AC-3 / at 400 V":"160 000 W","Of The Integrated Auxiliary Trip Unit":"3VA9608-0BB11","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":"630 A","Product Extension / Optional / Motor Drive":"Yes","Protection Function Of The Overcurrent Release":"LSI","number of CO contacts / for auxiliary contacts":"3","Of The Integrated Auxiliary Switch/Alarm Switch":"3VA9988-0AB12","Switching Capacity Class Of The Circuit Breaker":"M","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/0eb36652ce522f093395d6bd0dd27e34.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=569895&mlfb=3VA2440-5MN32-0BH0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA2440-5MN32-0BH0/alternatives.json"},"ai":{"faq":[{"question":"Does this MCCB include phase failure protection?","answer":"Yes, phase failure detection is built in, along with an undervoltage release for loss-of-control-voltage tripping."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA2440-5MN32-0BH0","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/3VA2440-5MN32-0BH0 when reusing this data.
