The ETU350 trip unit provides LSI protection: long-time (Ir) adjustable 400–1000 A for overload, short-time (Isd) 1.5–10 x Ir for selective coordination downstream, and instantaneous (Ii) fixed at 10 x In for bolted faults. Neutral protection is field-selectable OFF, 50%, or 100% of phase rating. The 3VA2 platform is Siemens' current-generation IEC breaker line, so firmware and accessory compatibility (auxiliary switches, shunt trips, communication modules) are supported. Four-pole construction with line and load lugs for 1000 A cable or bus bar. The nut keeper kit (included) retains mounting hardware during vertical or horizontal installation — saves a hand when torquing down in a tight enclosure. Two HQ auxiliary switches and one HQ trip alarm plus one electrical alarm switch are factory-installed. The HQ designation indicates high-rupture-capacity contacts rated for control-circuit isolation without external interposing relays.","metaTitle":"Siemens 3VA2510-6HN42-0AL0 Circuit Breaker, 1000A, 85kA @ 41","metaDescription":"Siemens 3VA2510-6HN42-0AL0 IEC frame 1000 circuit breaker, 85kA breaking capacity at 415V, ETU350 LSI protection, 1000A rated.
