The ETU350 electronic trip unit provides LSI protection: long-time (overload) adjustable from 320 A to 800 A, short-time (short-circuit with delay) adjustable from 1.5 to 10 times the Ir setting, and instantaneous fixed at 12 x In. For a 800 A breaker, that instantaneous pickup is 9,600 A — clearing hard bolted faults fast while coordinating with downstream devices. The shunt trip allows remote emergency-off or supervisory tripping — common in safety circuits or automated shutdown sequences. At 800 A continuous rating, it requires adequate ventilation and clearance for heat dissipation — typical for a main feeder breaker in an industrial switchboard or a large motor control center. The ETU350 is self-powered from the line-side current, so no external control power is needed for the trip unit. The shunt trip does require its own supply (208-277 V AC or 220-250 V DC) — verify polarity on the DC version.","metaTitle":"Siemens 3VA2580-5HN32-0KF0 Circuit Breaker, 800A, 55kA @ 415","metaDescription":"Siemens 3VA2580-5HN32-0KF0 IEC frame 1000 circuit breaker, 3-pole, 800A, Icu=55kA @ 415V, ETU350 LSI, shunt trip.
