Thermal derating is published across the full ambient range: full 400 A rating holds up to 50 °C, then steps down to 384 A at 55 °C, 376 A at 60 °C, 368 A at 65 °C, and 360 A at 70 °C. ## Coordination and integration detail The breaker ships with a basic switch (3VA2440-5HL32-0AA0) and an integrated auxiliary trip (3VA9688-0BL32) already fitted. That means the shunt trip coil and the auxiliary contacts are factory-installed — no field assembly required, and the wiring diagram stays clean for the panel builder. Dimensions: 138 mm wide, 248 mm tall, 110 mm deep. The 138 mm width is standard for a 3-pole 400 A frame in the SENTRON 3VA platform — it fits the same mounting footprint as other 3VA breakers in this current class, so a panel designed for a 3VA2116 or similar will accept this unit without re-drilling the backplate.","metaTitle":"Siemens 3VA2440-5HL32-0JH0 SENTRON MCCB, 400 A, 3-Pole, Shun","metaDescription":"Siemens SENTRON 3VA2440-5HL32-0JH0 molded case circuit breaker, 400 A rated, 3-pole, line protection with ETU320 release and shunt trip.
