The interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 500 V — figures that give substantial fault-clearing headroom in most industrial distribution panels without needing upstream current-limiting fuses. This is a motor-protection variant, meaning the trip unit is tailored for motor branch circuits — it handles the high inrush on start and provides overload protection matched to motor thermal damage curves, not just cable protection. The ETU350M is a microprocessor-based unit with adjustable settings for long-time pickup, short-time pickup, instantaneous, and ground-fault (though this specific order code ships without ground-fault monitoring). ## Panel fit and thermal derating The breaker measures 138 mm wide by 248 mm high by 110 mm deep. The 138 mm width is the pole-pitch footprint; three poles at roughly 46 mm per pole is standard for this frame size. Mounting is via the rear panel or DIN rail adapter (not specified here but typical for the 3VA2 platform). Thermal derating is published: the breaker carries the full 250 A continuously up to 50 °C ambient. At 55 °C it derates to 240 A, at 60 °C to 235 A, at 65 °C to 230 A, and at 70 °C to 225 A. For a panel with multiple breakers ganged together, the internal temperature rise will be higher than the room ambient — use the 50 °C column as the practical limit unless you have forced ventilation. Maximum power loss is 40 W. ## Auxiliary releases and switching capacity The integrated auxiliary trip is order code 3VA9608-0BB25. The breaker ships with 2 auxiliary switches, HQ (high-quality) type, for remote status indication. No communication function is fitted on this variant — no Modbus, PROFIBUS, or Ethernet interface. If you need remote monitoring of trip status and load current, you would add the communication module separately or choose a different 3VA2 variant with the ETU350M and a comms option. The basic switch supplied as the core is order code 3VA2325-5MN32-0AA0.","metaTitle":"Siemens 3VA2325-5MN32-0DC0 SENTRON MCCB, 250 A, Motor Protec","metaDescription":"Siemens 3VA2325-5MN32-0DC0 SENTRON molded case circuit breaker, 250 A rated continuous current, 3-pole motor protection with ETU350M electronic trip unit. 187 kA interrupting at 24","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":"250 A","at 45 °C":"250 A","at 50 °C":"250 A","at 55 °C":"240 A","at 60 °C":"235 A","at 65 °C":"230 A","at 70 °C":"225 A","Trip indicator":"No","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":"15 000","Undervoltage Release":"Yes","Communication Function":"No","Phase failure detection":"Yes","During Storage / Maximum":"80 °C","During Storage / Minimum":"-40 °C","Power loss [W] / maximum":"40 W","Auxiliary contact version":"2 auxiliary switches HQ","During Operation / Maximum":"70 °C","During Operation / Minimum":"-25 °C","Other Measurement Function":"No","Rated continuous current Iu":"250 A","Rated insulation voltage Ui":"800 V","Of The Supplied Basic Switch":"3VA2325-5MN32-0AA0","Design of the auxiliary release":"Undervoltage release (UVR)","Ground fault monitoring version":"Without","Of The Integrated Auxiliary Trip":"3VA9608-0BB25","Design of the overcurrent release":"ETU350M","Protection class IP / on the front":"IP40","Operating power / at AC-3 / at 400 V":"110 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.":"250 A","Adjustable response value current / li max.":"3 750 A","Adjustable response value current / li min.":"3 750 A","Adjustable response value current / lr min.":"100 A","Adjustable response value current / Isd max.":"3 750 A","Adjustable response value current / Isd min.":"750 A","Neutral conductors / upgradeable/retrofittable":"No","Number of CO contacts / for auxiliary contacts":"2","Protective function of the overcurrent release":"LSI","Of The Integrated Auxiliary Switch/Alarm Switch":"3VA9988-0AA12","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"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/ad4b9644ff5db6bf2edb958ed105bffe.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=570003&mlfb=3VA2325-5MN32-0DC0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA2325-5MN32-0DC0/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 3VA2325-5MN32-0DC0 and how do I get a price?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution.
