The thermal derating curve holds full 400 A up to 50 °C, then drops to 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C; if your panel ambient runs hot, size the breaker for the actual enclosure temperature, not the nameplate. Dimensions are 248 mm height, 138 mm width, 110 mm depth — a standard SENTRON 3VA2 frame size. The 3-pole block fits a 138 mm wide slot in a distribution panel or motor control center bucket. ## Trip unit and auxiliary functions The ETU550 trip unit includes a voltage trigger function and communication capability, so it can report status or accept a remote trip signal on a digital network. ## Environmental limits","metaTitle":"Siemens 3VA2340-6JP32-0JA0 SENTRON MCCB, 400 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA2340-6JP32-0JA0 molded case circuit breaker, 400 A rated continuous current, 3-pole, line protection with ETU550 electronic trip unit.
