At 85 kA SCCR, this breaker coordinates with upstream switchgear without requiring a current-limiting fuse or reactor, keeping the fault loop impedance low for downstream devices. ## ETU320 LI trip unit — adjustable protection, not fixed The ETU320 electronic trip unit provides LI (long-time and instantaneous) protection. Overload protection Ir is adjustable from 250 A to 630 A, matching the breaker's In of 630 A — so one frame covers a 250 A feeder or a 630 A main by dialing the pickup. Short-circuit protection Ii is adjustable from 1.5x to 9x In (945 A to 5670 A at the 630 A setting), letting you set instantaneous pickup above motor inrush or transformer magnetizing current without nuisance tripping. The LI curve suits line protection for cables, busbars, and transformers where ground-fault (G) protection is handled separately or downstream. ## Integrated undervoltage release and auxiliary contacts Also includes one HQ auxiliary switch and one HQ trip alarm switch. The HQ designation indicates a high-rupturing-capacity microswitch rated for control-circuit isolation, not just signaling. Both switches give the PLC or SCADA positive indication of breaker position and trip status without relying on the UVR coil state. ## What the nut keeper kit saves you On a panel build with multiple 3VA2 breakers, that adds up to measurable labor savings per unit.","metaTitle":"Siemens 3VA2463-6HL32-0BF0 630A 85kA ICB, ETU320 LI","metaDescription":"Siemens 3VA2463-6HL32-0BF0 circuit breaker, IEC frame 630, 85 kA @ 415 V, ETU320 LI, 630 A, active lifecycle, sourced to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Molded Case Circuit Breakers (MCCB)"],"specifications":{"lifecycle_stage":"current"}},"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=1109933&mlfb=3VA2463-6HL32-0BF0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA2463-6HL32-0BF0/alternatives.json"},"ai":{"faq":[{"question":"What is the breaking capacity of this breaker?","answer":"Icu = 85 kA at 415 V AC, breaking capacity class H per IEC 60947-2."},{"question":"What trip unit does this breaker use and what are the adjustment ranges?","answer":"ETU320 LI electronic trip unit.
