The 4-pole construction with adjustable N conductor protection (OFF, 50%, 100%) suits it for 3-phase + neutral distribution where unbalanced loads or harmonic currents need a monitored neutral path. The ETU350 electronic trip unit provides LSI protection: Long-time (Ir) adjustable 40 A to 100 A for overload, Short-time (Isd) adjustable 1.5 to 10 x Ir for selective coordination with downstream breakers, and Instantaneous (Ii) fixed at 12 x In for fast fault clearing. The adjustable short-time delay lets an engineer build a selective trip hierarchy — a downstream 50 A breaker clears a branch fault before this main trips, keeping the rest of the panel live. The integrated shunt trip (left-side, 110-127 V AC 50/60 Hz / DC) allows remote tripping from an E-stop or PLC output. The 3VA2 platform is Siemens' current-generation IEC molded case breaker line, succeeding the 3VL series. The ETU350 electronic trip unit is the standard LSI variant for this frame size. ## Deployment context The 4-pole form factor with adjustable N protection makes it a natural fit for main or feeder breaker duty in a 400/415 V three-phase distribution board serving motor control centers, lighting panels, or UPS bypass circuits. The 85 kA SCCR at 415 V meets the fault-current requirement for most industrial service-entrance positions.","metaTitle":"Siemens 3VA2010-6HN42-0JF0 Circuit Breaker, 85kA @ 415V, 100","metaDescription":"Siemens 3VA2010-6HN42-0JF0 IEC frame 100 circuit breaker, breaking capacity class H Icu=85kA @ 415V, 4-pole, ETU350 LSI protection, In=100A.
