Breaking capacity is 187 kA at 240 V AC, tapering to 121 kA at 415/440 V, 75.6 kA at 500 V, and 7.5 kA at 690 V. Mounting is via screw-clamp or optional DIN-rail adapter; the 138 mm width occupies three 45 mm pole spaces on a DIN rail. Maximum power dissipation is 40 W at rated load — that heat needs to be factored into the enclosure's thermal rise calculation, especially in a sealed stainless steel panel on a washdown line. ## Motor protection specifics The design is explicitly for motor protection, meaning the trip curve and thermal memory are tuned for motor inrush and overload profiles rather than straight cable protection. The undervoltage release (UVR) is a separate auxiliary release that can be wired to a safety circuit or E-stop chain to drop the breaker on command. The basic switch variant is 3VA2325-5MN32-0AA0 — this is the internal switching mechanism. The 3VA2325-5MN32-0DA0 adds the undervoltage release and the motor protection trip unit. No auxiliary switch is fitted as standard; if you need a status contact for the PLC, you will add an external auxiliary switch block.","metaTitle":"Siemens 3VA2325-5MN32-0DA0 SENTRON MCCB, 250A, 3-Pole, Motor","metaDescription":"Siemens 3VA2325-5MN32-0DA0 SENTRON molded case circuit breaker, 250A rated current at 40-70°C, 3-pole, motor protection design with undervoltage release and phase failure detection","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":"7.5 kA","at 40 °C":"250 A","at 45 °C":"250 A","at 50 °C":"250 A","at 55 °C":"250 A","at 60 °C":"250 A","at 65 °C":"250 A","at 70 °C":"250 A","Depth [In]":"4.33 in","Width [In]":"5.43 in","Height [In]":"9.76 in","Trip Indicator":"No","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":"40 W","During Operation / Maximum":"70 °C","During Operation / Minimum":"-25 °C","Other Measurement Function":"No","Of The Supplied Basic Switch":"3VA2325-5MN32-0AA0","Design Of The Auxiliary Switch":"Without","Design Of The Auxiliary Release":"undervoltage release (UVR)","Ground-Fault Monitoring Version":"Without","Continuous Current / Rated Value":"250 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":"55 000 W","operating power / at AC-3 / at 400 V":"110 000 W","Of The Integrated Auxiliary Trip Unit":"3VA9608-0BB25","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":"400 A","Product Extension / Optional / Motor Drive":"Yes","Protection Function Of The Overcurrent Release":"LSI","number of CO contacts / for auxiliary contacts":"0","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/ad4b9644ff5db6bf2edb958ed105bffe.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=570002&mlfb=3VA2325-5MN32-0DA0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA2325-5MN32-0DA0/alternatives.json"},"ai":{"faq":[{"question":"What is the breaking capacity of 3VA2325-5MN32-0DA0 at 240 V?","answer":"187 kA at 240 V AC, which is a high-interrupting rating suitable for high-fault-current installations."},{"question":"Does 3VA2325-5MN32-0DA0 include phase failure protection?","answer":"Yes, phase failure detection is built in, so it will trip on loss of one phase to protect the motor from single-phasing."},{"question":"Where can I buy 3VA2325-5MN32-0DA0 and how is it quoted?","answer":"This part is sourced and quoted to order through independent distribution against an RFQ.
