The interrupting ratings are the real story: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 40 kA at 690 V. Those are high-end fault-clearing numbers; this breaker handles bolted faults in heavy industrial distribution without cascading upstream. The overcurrent release is an ETU550 — electronic trip unit, typically offering LSI (long-time, short-time, instantaneous) protection curves with adjustable settings. Communication function is built in, so it can talk to a higher-level system for monitoring and remote trip. It ships with three auxiliary switches (HQ type) for status feedback. Power loss maxes at 96 W — plan for that heat in a closed enclosure. Mechanical endurance is 15,000 cycles; that's typical for a 400 A frame — not a daily-switch application, but fine for infrequent maintenance disconnects. The breaker footprint is 138 mm wide, 248 mm tall, 110 mm deep. Verify gland-plate cutout against the 138 mm width; it's wider than a typical 250 A frame, so a panel originally laid out for a smaller MCCB may need a filler plate.","metaTitle":"Siemens 3VA2340-6JP32-0AD0 MCCB, 400 A, 242 kA at 240 V","metaDescription":"Siemens SENTRON 3VA2340-6JP32-0AD0 molded case circuit breaker, 400 A rated, 242 kA at 240 V, 3-pole, line protection, ETU550, current 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":"110 mm","Width":"138 mm","Height":"248 mm","at 240 V":"242 kA","at 415 V":"187 kA","at 440 V":"187 kA","at 500 V":"121 kA","at 690 V":"40 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","Trip indicator":"No","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":"Yes","Phase failure detection":"No","During Storage / Maximum":"80 °C","During Storage / Minimum":"-40 °C","Power loss [W] / maximum":"96 W","Auxiliary contact version":"3 auxiliary switches HQ","During Operation / Maximum":"70 °C","During Operation / Minimum":"-25 °C","Other Measurement Function":"No","Rated continuous current Iu":"400 A","Rated insulation voltage Ui":"800 V","Of The Supplied Basic Switch":"3VA2340-6JP32-0AA0","Design of the auxiliary release":"Without auxiliary release","Ground fault monitoring version":"Without","Of The Integrated Auxiliary Trip":"3VA9608-0BB24","Design of the overcurrent release":"ETU550","Protection class IP / on the front":"IP40","Reference code / acc. to DIN EN 81346-2":"Q","Adjustable response value time / tr max.":"17","Adjustable response value time / tr min.":"0.5","Adjustable response value time / tsd max.":"0.5 s","Adjustable response value time / tsd min.":"0.05 s","Undervoltage Release With Leading Contact":"No","Product extension / optional / motor drive":"Yes","Adjustable response value current / Ir max.":"400 A","Adjustable response value current / li max.":"4 000 A","Adjustable response value current / li min.":"600 A","Adjustable response value current / lr min.":"160 A","Adjustable response value current / Isd max.":"4 000 A","Adjustable response value current / Isd min.":"240 A","Neutral conductors / upgradeable/retrofittable":"Yes","Number of CO contacts / for auxiliary contacts":"3","Protective function of the overcurrent release":"LSI","Of The Integrated Auxiliary Switch/Alarm Switch":"3VA9988-0AA12","Switching capacity class of the circuit breaker":"H","Max. rated operational current of the frame size":"400 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.":"35 x 10","Type of connectable conductor cross-section, connection screw, width x thickness , min.":"20 x 1"}},"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=187818&mlfb=3VA2340-6JP32-0AD0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA2340-6JP32-0AD0/alternatives.json"},"ai":{"faq":[{"question":"How do I get current pricing and availability for 3VA2340-6JP32-0AD0?","answer":"Pricing and stock are confirmed at quote time.
