That rating places it in the high-break tier of the 3VA2 family, sized for main feeders or large branch circuits where fault current exceeds 50 kA. The ETU350 electronic trip unit provides LSI protection: long-time (Ir) adjustable 100 A to 250 A, short-time (Isd) 1.5 to 10 times Ir, and instantaneous (Ii) fixed at 10 times In. Neutral conductor protection is selectable OFF, 50%, or 100% of phase pickup — a feature for 4-wire systems where the neutral needs its own overload element. Mounts in a standard panel or enclosure on the 3VA2 busbar system or via rear terminals. The nut keeper kit (included in the order code suffix) captures the mounting nuts during installation — saves time when working in tight enclosures.","metaTitle":"Siemens 3VA2225-6HN42-0AD0 Circuit Breaker, 85kA @ 415V, 250","metaDescription":"Siemens 3VA2 IEC frame 250 breaker, class H Icu=85kA @ 415V, 4-pole, ETU350 LSI protection, In=250A, active lifecycle.
