The ETU350 electronic trip unit provides LSI protection: long-time (Ir) adjustable 250 A to 630 A, short-time (Isd) 1.5 to 9 times Ir, and instantaneous (Ii) fixed at 9 times In. That gives selective coordination headroom downstream — the short-time delay lets a feeder breaker ride through a branch fault without tripping the main. For a BOM-critical line item at this current rating, the ETU350 LSI variant is specified into new switchgear designs and held as a critical spare for existing 3VA2 installations. Designed for busbar connection in a panelboard or switchgear enclosure — the busbar connection pattern matches the 3VA2 frame 630 footprint, so it lands directly on the existing copper risers without adapter plates.","metaTitle":"Siemens 3VA2463-0HN32-0KF0 Circuit Breaker, 630A, 200kA @ 41","metaDescription":"Siemens 3VA2463-0HN32-0KF0 IEC frame 630 circuit breaker, 200 kA breaking capacity at 415 V AC, ETU350 LSI trip unit, 630 A rated current, shunt trip.
