The ETU350 electronic trip unit gives LSI protection: long-time (Ir) adjustable 160–400 A, short-time (Isd) 1.5–10 x Ir, and instantaneous (Ii) fixed at 10 x In. This selectivity profile suits it as a main or feeder breaker in a distribution panel where you need coordination with downstream devices. ## Built-in accessories and deployment context The auxiliary and alarm switches feed status back to a PLC or indicator panel. The nut keeper kit simplifies panel mounting on a DIN rail or backplate; no loose hardware to lose during installation.","metaTitle":"Siemens 3VA2340-5HN32-0DF0 Circuit Breaker, 55kA @ 415V, 400","metaDescription":"Siemens 3VA2340-5HN32-0DF0 IEC frame 400 breaker, 55kA breaking capacity, ETU350 LSI, 400A, undervoltage release.
