The TM240 release is thermal-magnetic, so it handles overloads thermally and short-circuits magnetically; no electronic trip unit to program or fail. Dimensions are 248 mm high, 138 mm wide, 110 mm deep — standard 3-pole MCCB footprint for a 400 A frame. Rated 400 A from 40 °C up to 50 °C; derates to 392 A at 55 °C, 384 A at 60 °C, 376 A at 65 °C, and 367 A at 70 °C.","metaTitle":"SENTRON 3VA1340-4EF32-0KD0 MCCB, 400 A, 3-Pole, 76 kA at 415","metaDescription":"SENTRON 3VA1340-4EF32-0KD0 molded case circuit breaker, 400 A, 3-pole, line protection, TM240 release, 76 kA at 415 V.
