It carries the ETU350 electronic trip unit configured for LSI protection — long-time (Ir adjustable 160–400 A), short-time (Isd 1.5–10×Ir), and instantaneous (Ii fixed at 10×In). The ETU350 LSI trip unit gives the commissioning engineer granular adjustment of long-time pickup and delay, short-time pickup and delay, and a fixed instantaneous threshold, enabling selective coordination with downstream feeders. The shunt trip at 208–277 V AC allows remote tripping from a safety circuit or emergency-stop chain.","metaTitle":"Siemens 3VA2340-5HN32-0KB0 Circuit Breaker, 55kA @ 415V, 400","metaDescription":"Siemens 3VA2340-5HN32-0KB0 circuit breaker, IEC frame 400, breaking capacity class M Icu=55kA @ 415V, 3-pole, ETU350 LSI, In=400A.
