The 187 kA interrupting rating at 240 V (derating to 121 kA at 415/440 V, 75.6 kA at 500 V, and 17 kA at 690 V) gives selectivity headroom in high-fault panels; the 20 000 mechanical endurance cycles match typical MCCB life for a motor branch circuit. The MCCB occupies a 105 mm wide by 181 mm high by 86 mm deep footprint — standard for a 3-pole SENTRON 3VA frame. It mounts via screw terminals to a backplate or DIN rail adapter; the 86 mm depth leaves clearance for rear-connected busbars in a typical 400 mm deep enclosure.","metaTitle":"Siemens 3VA2140-5MN32-0AH0 SENTRON MCCB, 40 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA2140-5MN32-0AH0 molded case circuit breaker, 3-pole, 40 A, 187 kA at 240 V, ETU350M trip unit, motor protection, active production, sourced to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Molded Case Circuit Breakers (MCCB)"],"specifications":{"Depth":"86 mm","Width":"105 mm","Height":"181 mm","at 240 V":"187 kA","at 415 V":"121 kA","at 440 V":"121 kA","at 500 V":"75.6 kA","at 690 V":"17 kA","at 40 °C":"40 A","at 45 °C":"40 A","at 50 °C":"40 A","at 55 °C":"38.4 A","at 60 °C":"37.6 A","at 65 °C":"36.8 A","at 70 °C":"36 A","Trip indicator":"Yes","Number of poles":"3","Product version":"Motor protection","Voltage trigger":"No","lifecycle_stage":"current","Product brand name":"SENTRON","Product designation":"Molded case circuit breaker","Latching - endurance":"20 000","Undervoltage Release":"No","Communication Function":"No","Phase failure detection":"Yes","During Storage / Maximum":"80 °C","During Storage / Minimum":"-40 °C","Power loss [W] / maximum":"75 W","Auxiliary contact version":"2 auxiliary switches + 1 trip alarm switch HQ","During Operation / Maximum":"70 °C","During Operation / Minimum":"-25 °C","Other Measurement Function":"No","Rated continuous current Iu":"40 A","Rated insulation voltage Ui":"800 V","Of The Supplied Basic Switch":"3VA2140-5MN32-0AA0","Design of the auxiliary release":"Without auxiliary release","Ground fault monitoring version":"Without","Design of the overcurrent release":"ETU350M","Protection class IP / on the front":"IP40","Operating power / at AC-3 / at 400 V":"15 W","Reference code / acc. to DIN EN 81346-2":"Q","Adjustable response value time / tr max.":"17","Adjustable response value time / tr min.":"4","Adjustable response value time / tsd max.":"0.03 s","Adjustable response value time / tsd min.":"0.03 s","Undervoltage Release With Leading Contact":"No","Product extension / optional / motor drive":"Yes","Adjustable response value current / Ir max.":"40 A","Adjustable response value current / li max.":"600 A","Adjustable response value current / li min.":"600 A","Adjustable response value current / lr min.":"16 A","Adjustable response value current / Isd max.":"600 A","Adjustable response value current / Isd min.":"120 A","Neutral conductors / upgradeable/retrofittable":"No","Number of CO contacts / for auxiliary contacts":"3","Protective function of the overcurrent release":"LSI","Of The Integrated Auxiliary Switch/Alarm Switch":"3VA9988-0AB12","Switching capacity class of the circuit breaker":"M","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"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/cda978e31ec81fb539d5632cb59bd0b3.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=569649&mlfb=3VA2140-5MN32-0AH0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA2140-5MN32-0AH0/alternatives.json"},"ai":{"faq":[{"question":"What is the interrupting rating of 3VA2140-5MN32-0AH0 at 415 V?","answer":"The interrupting rating is 121 kA at 415 V (and at 440 V), with derating to 75.6 kA at 500 V and 17 kA at 690 V."},{"question":"Does this MCCB include phase failure detection?","answer":"Yes, the ETU350M trip unit includes phase failure detection, protecting the motor from single-phasing."},{"question":"Where can I buy 3VA2140-5MN32-0AH0?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution.
