It uses an ETU350 trip unit configured for LSI protection — long-time (Ir adjustable 250–630 A), short-time (Isd 1.5–9× Ir), and instantaneous (Ii fixed at 9× In). The neutral conductor protection is adjustable: OFF, 50%, or 100% of phase current. This is a line-protection build — it's meant for main or feeder duty in a distribution panel, not motor branch circuit protection. The 55 kA Icu at 415 V places this in breaking capacity class M — it's sized for high-fault installations where upstream transformers or large motor groups can deliver substantial short-circuit current. The 630 A frame (In) with Ir adjustable down to 250 A means you can cable this for a 630 A bus but set the overload pickup to match a smaller downstream load, preserving selectivity headroom. The undervoltage release (208–230 V AC) drops the breaker if control voltage is lost — common in emergency-stop chains or mains-loss schemes. Verify the release coil voltage matches your control transformer before panel wiring.","metaTitle":"Siemens 3VA2463-5HN42-0DL0 Circuit Breaker, 630A, 55kA @ 415","metaDescription":"Siemens 3VA2463-5HN42-0DL0 IEC frame 630 circuit breaker, 55kA breaking capacity at 415V, ETU350 LSI protection, 630A rated.

For a 400 V distribution board fed by a transformer of 2000 kVA or larger, this rating provides adequate fault-clearing capability without cascading upstream. It's class M — mid-range in the 3VA2 family between standard (S) and high (H) breaking capacities."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA2463-5HN42-0DL0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3VA2463-5HN42-0DL0 when reusing this data.
