Its interrupting capacity hits 187 kA at 240 V and 121 kA at 415/440 V, meaning it can safely clear high-fault conditions on large transformer-fed distribution or heavy industrial feeders without cascading upstream. The ETU560 electronic trip unit provides adjustable long-time, short-time, instantaneous, and ground-fault protection; the ground-fault monitoring uses summation current formation on the L-conductor, so it catches leakage without a separate neutral CT. Dimensions are 105 mm wide, 181 mm high, 86 mm deep — a standard SENTRON 3VA footprint that drops into the same cutout and bus-bar spacing as other 3VA frame-size breakers. ## Communication and monitoring A communication function is built in — the ETU560 supports integration with higher-level energy management or control systems via the SENTRON communication platform, enabling remote trip indication, current metering, and parameter adjustment. The voltage trigger feature allows a remote signal to initiate a trip, useful for emergency-off or load-shedding schemes.","metaTitle":"Siemens 3VA2063-5JQ32-0KH0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2063-5JQ32-0KH0 molded case circuit breaker, 63 A continuous at 70 °C, 187 kA at 240 V, ETU560 release, line protection, current production, available to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Molded Case Circuit Breakers (MCCB)"],"specifications":{"Depth":"86 mm","Width":"105 mm","Height":"181 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":"3 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]":"4.13 in","Height [In]":"7.13 in","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","Undervoltage Release":"No","Communication Function":"Yes","During Storage / Maximum":"80 °C","During Storage / Minimum":"-40 °C","power loss [W] / maximum":"5.4 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":"No","rated insulation voltage Ui":"800 V","Of The Supplied Basic Switch":"3VA2063-5JQ32-0AA0","Courant permanent assigné Iu":"63 A","Ground-Fault Monitoring Version":"Summation current formation L-conductor","Design Of The Overcurrent Release":"ETU560","protection class IP / on the front":"IP40","design of the N-conductor protection":"adjustable OFF; 40% to 160%","reference code / acc. to IEC 81346-2":"Q","Of The Integrated Auxiliary Trip Unit":"3VA9688-0BL33","Undervoltage Release With Leading Contact":"No","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":"Yes","Protection Function Of The Overcurrent Release":"LSIG","number of CO contacts / for auxiliary contacts":"3","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":"100 A","Mechanical Service Life (Switching Cycles) / Typical":"25 000","Type Of Electrical Connection / For Main Current Circuit":"on both sides nut keeper kit","Arrangement Of Electrical Connectors / For Main Current Circuit":"Front terminal","Type of connectable conductor cross-section, connection screw, width x thickness , max.":"25 x 8 mm","Type of connectable conductor cross-section, connection screw, width x thickness , min.":"13 x 1 mm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=193050&mlfb=3VA2063-5JQ32-0KH0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA2063-5JQ32-0KH0/alternatives.json"},"ai":{"faq":[{"question":"How do I get current pricing and availability for 3VA2063-5JQ32-0KH0?","answer":"Submit an RFQ through this listing.
