At 415 V it still breaks 121 kA, so it fits main breaker positions in 400 V distribution panels where fault current runs high. The 110 mm depth and 138 mm width keep it within a standard MCCB footprint for retrofit into existing SENTRON or third-party cubicles. ## Derating and thermal budget Maximum power loss is 162 W, which adds to the enclosure's heat load; factor that into the ventilation or cooling calculation. Communication function is built in, so it can report status to a higher-level controller or BMS. No undervoltage release or phase failure detection on this variant.","metaTitle":"Siemens 3VA2463-5KP32-0HH0 SENTRON MCCB, 630 A, 187 kA","metaDescription":"Siemens 3VA2463-5KP32-0HH0 SENTRON molded case circuit breaker, 630 A at 40 °C, 187 kA at 240 V, 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":"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":"630 A","at 45 °C":"600 A","at 50 °C":"570 A","at 55 °C":"540 A","at 60 °C":"510 A","at 65 °C":"480 A","at 70 °C":"450 A","Trip indicator":"Yes","Number of poles":"3","Product version":"Line protection","Voltage trigger":"Yes","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":"162 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":"Yes","Rated continuous current Iu":"630 A","Rated insulation voltage Ui":"800 V","Of The Supplied Basic Switch":"3VA2463-5KP32-0AA0","Design of the auxiliary release":"Shunt trip (STL)","Ground fault monitoring version":"Without","Of The Integrated Auxiliary Trip":"3VA9688-0BL30","Design of the overcurrent release":"ETU850","Protection class IP / on the front":"IP40","Reference code / acc. to DIN EN 81346-2":"Q","Adjustable response value time / tr max.":"12","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.":"630 A","Adjustable response value current / li max.":"5 670 A","Adjustable response value current / li min.":"945 A","Adjustable response value current / lr min.":"252 A","Adjustable response value current / Isd max.":"5 670 A","Adjustable response value current / Isd min.":"378 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":"630 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/7ff193dd53a0856db1ca969741fab18b.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=340799&mlfb=3VA2463-5KP32-0HH0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA2463-5KP32-0HH0/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 3VA2463-5KP32-0HH0 and get a price?","answer":"This part is sourced to order against an RFQ through independent distribution.
