Continuous current is 400 A flat from 40 °C through 50 °C, then derates to 392 A at 55 °C, 384 A at 60 °C, 376 A at 65 °C, and 367 A at 70 °C. If your panel ambient runs 55 °C or higher, the 400 A label doesn't hold — size the load at the derated figure or move to a higher-frame breaker. In a sealed panel with multiple breakers, that thermal load adds up; factor it into the cabinet cooling calculation or you'll cook the trip unit. The storage range is wider because there's no current flowing — that's the handling and warehouse limit, not the running limit. This breaker is current production. The 110 mm depth means it projects less than many older frames, which helps in shallow enclosures.","metaTitle":"Siemens 3VA1340-6EF32-0AB0 SENTRON MCCB, 400A, 220kA at 240V","metaDescription":"Siemens 3VA1340-6EF32-0AB0 SENTRON molded case circuit breaker, 3-pole, 400A rated at 40°C, 220kA breaking capacity at 240V AC.
