Thermal derating is published: the 400 A rating holds from 40 °C 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. Plan the enclosure ventilation accordingly if the ambient exceeds 50 °C. Compared to the smaller 3VA2116-5JP32-0AE0 (a 160 A frame), this 3VA2340 carries a 400 A frame with substantially higher breaking capacity — 242 kA vs the 160 A unit's lower ratings — so a panel originally specified for the 160 A breaker cannot simply drop in the 400 A version without checking busbar ampacity, lug size, and enclosure thermal limits.","metaTitle":"Siemens 3VA2340-6JP32-0BC0 SENTRON MCCB, 400 A, 3-Pole, 242","metaDescription":"Siemens SENTRON 3VA2340-6JP32-0BC0 molded case circuit breaker. 400 A continuous, 3-pole, breaking capacity 242 kA at 240 V.
