It carries an ETU350 LSI electronic trip unit with overload protection adjustable from 320 A to 800 A, short-circuit protection Isd=1.5...10 x Ir, and instantaneous Ii=12 x In. The N conductor protection is adjustable (OFF, 50%, 100%). A shunt trip left accessory for 24 V AC 50/60 Hz / 24-30 V DC is integrated, and the unit includes a nut keeper kit and provisions for 2 auxiliary switches. The ETU350 LSI electronic trip provides adjustable long-time (L), short-time (S), and instantaneous (I) protection curves, allowing fine coordination with downstream feeders. The adjustable N conductor protection (OFF, 50%, 100%) suits 4-wire systems where neutral current monitoring is required. The integrated shunt trip left at 24 V AC/DC enables remote tripping from a safety circuit or emergency-stop chain. The nut keeper kit simplifies busbar connection — no loose hardware to drop into live gear.","metaTitle":"Siemens 3VA2580-5HN42-0HH0 Circuit Breaker, 800A, 55kA @ 415","metaDescription":"Siemens 3VA2580-5HN42-0HH0 IEC frame 1000 circuit breaker, 4-pole, 800A, Icu=55kA @ 415V, ETU350 LSI, shunt trip.
