The interrupting capacity at 240 V is 330 kA, which drops to 242 kA at 415 V and 440 V, then to 187 kA at 500 V, and finally to 3.7 kA at 690 V. The communication function (listed as present on this variant) means it can talk to a higher-level system for power monitoring and remote trip indication, which saves a maintenance electrician from having to walk the whole line to find what opened. The ground-fault monitoring uses summation current formation on L + N, so it catches leakage on the neutral as well as the phases. Power loss is 4 W maximum, which is low enough that you don't need to factor heat into the enclosure sizing for a single breaker. ## Deployment context This breaker is a panel-mounted device — it bolts into a switchboard or a distribution panel, not onto a DIN rail.","metaTitle":"Siemens 3VA2163-7KQ46-0AA0 SENTRON MCCB, 63 A, 4-Pole, 240V","metaDescription":"Siemens 3VA2163-7KQ46-0AA0 SENTRON molded case circuit breaker, 63 A rated current (no derating to 70 °C), 4-pole, 240V 330 kA breaking capacity, ETU860 release, communication capa","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Molded Case Circuit Breakers (MCCB)"],"specifications":{"Depth":"86 mm","Width":"140 mm","Height":"181 mm","at 240 V":"330 kA","at 415 V":"242 kA","at 440 V":"242 kA","at 500 V":"187 kA","at 690 V":"3.7 kA","at 40 °C":"63 A","at 45 °C":"63 A","at 50 °C":"63 A","at 55 °C":"63 A","at 60 °C":"63 A","at 65 °C":"63 A","at 70 °C":"63 A","Depth [In]":"3.39 in","Width [In]":"5.51 in","Height [In]":"7.13 in","Trip Indicator":"No","Number Of Poles":"4","Product version":"Line protection","Voltage Trigger":"No","lifecycle_stage":"current","Product Brand Name":"SENTRON","Product Designation":"Molded case circuit breaker","Undervoltage Release":"No","Communication Function":"Yes","During Storage / Maximum":"80 °C","During Storage / Minimum":"-40 °C","power loss [W] / maximum":"4 W","During Operation / Maximum":"70 °C","During Operation / Minimum":"-25 °C","Other Measurement Function":"Yes","Courant permanent assigné Iu":"63 A","Ground-Fault Monitoring Version":"Summation current formation L + N conductor","Tension assignée d'isolement Ui":"800 V","Design Of The Overcurrent Release":"ETU860","protection class IP / on the front":"IP40","reference code / acc. to IEC 81346-2":"Q","Product Extension / Optional / Motor Drive":"Yes","Adjustable response value current / lg max.":"63 A","Adjustable response value current / lg min.":"16 A","Adjustable response value current / li max.":"756 A","Adjustable response value current / li min.":"95 A","Neutral conductors / upgradeable/retrofittable":"No","Protection Function Of The Overcurrent Release":"LSIG","number of CO contacts / for auxiliary contacts":"0","Switching Capacity Class Of The Circuit Breaker":"C","Max. rated operational current of the frame size":"160 A","Mechanical Service Life (Operating Cycles) / Typical":"25 000","Type Of Electrical Connection / For Main Current Circuit":"double-sided box terminal","Arrangement Of Electrical Connectors / For Main Current Circuit":"Front terminal","Type of connectable conductor cross-section, round conductor terminal, stranded":"1 x (6-120 mm²)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/b27f8f8fa25a6619d6d76a928fe2e8a2.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=183113&mlfb=3VA2163-7KQ46-0AA0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA2163-7KQ46-0AA0/alternatives.json"},"ai":{"faq":[{"question":"How do I get current pricing and availability for 3VA2163-7KQ46-0AA0?","answer":"Submit an RFQ through this listing.
