This makes it suitable for main feeder or large motor protection in 400 V-class distribution where high SCCR is needed to avoid cascading failures upstream. The ETU350 electronic trip unit provides LSI protection (long-time, short-time, instantaneous) with adjustable settings, including a fixed instantaneous pickup at 12 500 A (10× In). The 4-pole design includes adjustable neutral protection (OFF, 50%, 100%). Front IP40 rating suits panel-mount indoor use; the 120 mm depth fits standard 3VA2 switchboard form factors.","metaTitle":"Siemens 3VA2612-6HN42-0AA0 SENTRON MCCB, 1250 A, H Class, 4-","metaDescription":"Siemens 3VA2612-6HN42-0AA0 SENTRON molded case circuit breaker, 1250 A continuous, H switching capacity, 4-pole, ETU350 LSI trip.
