Above 50 °C it steps down: 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, 300 A at 70 °C. It also supports communication — the breaker has a communication function, so it can talk to a BMS or SCADA system for remote monitoring and trip-event logging. An undervoltage release (UVR) is built in — part number 3VA9608-0BB11 for the integrated auxiliary trip. If your safety circuit needs to drop the breaker on loss of control voltage, that release is already specified. The breaker measures 138 mm wide by 248 mm tall by 110 mm deep — a standard SENTRON 3VA frame size for 400 A. The 110 mm depth leaves room for cable bending radius in a 600 mm deep enclosure. Maximum power dissipation is 98.5 W at rated current.","metaTitle":"Siemens 3VA2340-5JP32-0BH0 SENTRON MCCB, 400 A, 187 kA","metaDescription":"Siemens SENTRON 3VA2340-5JP32-0BH0 molded case circuit breaker, 400 A rated continuous current, 187 kA breaking at 240 V, ETU550 release, undervoltage release, communication capabl","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":"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":"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":"Yes","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":"Yes","Communication Function":"Yes","Phase failure detection":"No","During Storage / Maximum":"80 °C","During Storage / Minimum":"-40 °C","Power loss [W] / maximum":"98.5 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":"400 A","Rated insulation voltage Ui":"800 V","Of The Supplied Basic Switch":"3VA2340-5JP32-0AA0","Design of the auxiliary release":"Undervoltage release (UVR)","Ground fault monitoring version":"Without","Of The Integrated Auxiliary Trip":"3VA9608-0BB11","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":"3VA9988-0AB12","Switching capacity class of the circuit breaker":"M","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=306895&mlfb=3VA2340-5JP32-0BH0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA2340-5JP32-0BH0/alternatives.json"},"ai":{"faq":[{"question":"How do I get current pricing and availability for 3VA2340-5JP32-0BH0?","answer":"Submit an RFQ through this listing.

For a 400 A main breaker with electronic trip and communication, this 3VA2340-5JP32-0BH0 is the direct fit — no drop-in substitute from the 3VA1 family exists at this current level."},{"question":"What is the depth of 3VA2340-5JP32-0BH0?","answer":"The depth is 110 mm. That's the dimension from the mounting surface to the front of the breaker, including the rotary handle."},{"question":"What is the width of 3VA2340-5JP32-0BH0?","answer":"The width is 138 mm.

The 3VA2340-5JP32-0BH0 is a physically larger 400 A frame — you would need to rework the bus bars, cable lugs, and possibly the enclosure cutout."},{"question":"What compliance documentation does this brand provide for 3VA2340-5JP32-0BH0?","answer":"Siemens SENTRON breakers carry IEC/EN 60947-2 certification and are typically UL 489 listed for the North American market. RoHS and REACH declarations are available from Siemens documentation.
