The 400 A frame and 55 kA Icu at 415 V place this breaker in the main or large-feeder position in a low-voltage switchboard. The ETU350 electronic trip offers LSI curves, meaning it can discriminate with downstream breakers on short-time delay — critical for selective coordination in a plant power system.","metaTitle":"Siemens 3VA2340-5HN32-0LL0 Circuit Breaker, 400A, 55kA @ 415","metaDescription":"Siemens 3VA2340-5HN32-0LL0 IEC frame 400 circuit breaker, 3-pole, 55kA breaking capacity @ 415V, ETU350 LSI protection, In=400A.
