The shunt trip is wired separately from the main power path — verify coil voltage compatibility with your control voltage before wiring. ## Mounting and footprint Dimensions are 248 mm high, 138 mm wide, 110 mm deep — a standard SENTRON 3VA frame size for 400 A.","metaTitle":"Siemens 3VA2340-6HN32-0JC0 SENTRON MCCB, 400 A, 3-Pole, Shun","metaDescription":"Siemens SENTRON 3VA2340-6HN32-0JC0 molded case circuit breaker, 400 A continuous, 3-pole, line protection with shunt trip release.
