Maximum power loss is 96 W at rated current — a factor for enclosure thermal calculations, particularly in sealed or high-density cabinets. Dimensions are 248 mm height, 138 mm width, 110 mm depth — a standard 3-pole MCCB footprint for the 400 A frame class. Verify the mounting hole pattern and busbar spacing against the existing panel layout before ordering. The breaker does not include an undervoltage release, voltage trigger, or ground-fault monitoring module as standard — these are external accessories if required.","metaTitle":"Siemens 3VA2340-6HN32-0AA0 SENTRON MCCB, 400 A, 3-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2340-6HN32-0AA0 molded case circuit breaker, 400 A continuous, 3-pole, ETU350 trip unit.
