It carries the ETU850 electronic overcurrent release, which supports communication functions — meaning it can report trip events and load profiles over the SENTRON bus, useful for predictive maintenance on a 250 MW solar plant or a critical conveyor line. At 40 °C ambient the breaker carries 630 A; derate linearly to 450 A at 70 °C (–). For a panel that runs hot — say a non-ventilated enclosure near a furnace line — the 70 °C figure of 450 A is the real continuous limit, not the nameplate 630 A. Width of 138 mm is a 3-pole frame; verify cutout spacing if swapping from a different MCCB brand. Maximum power loss is 162 W at rated current. ## Interrupting performance across voltages The interrupting capacity drops with system voltage: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V (–). For a 480 V distribution panel the 75.6 kA rating still covers most transformer-fed services; at 690 V the 17 kA figure is adequate for downstream motor circuits but not for a main tie.","metaTitle":"Siemens SENTRON 3VA2463-5KP32-0AE0 MCCB, 630 A, 187 kA","metaDescription":"Siemens SENTRON 3VA2463-5KP32-0AE0 molded case circuit breaker, 630 A rated current, 187 kA interrupting at 240 V, ETU850 release, current 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":"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":"162 W","Auxiliary contact version":"4 auxiliary switches 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":"Without auxiliary release","Ground fault monitoring version":"Without","Of The Integrated Auxiliary Trip":"3VA9608-0BB24","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":"4","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":"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=76856&mlfb=3VA2463-5KP32-0AE0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA2463-5KP32-0AE0/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 3VA2463-5KP32-0AE0 and how is it quoted?","answer":"This part is sourced to order through independent distribution.
