Rated continuous current holds at 400 A up to 50 °C ambient, then derates to 384 A at 55 °C, 376 A at 60 °C, 368 A at 65 °C, and 360 A at 70 °C. For a panel running at 55 °C ambient, expect 384 A continuous capability — factor that into busbar and cable sizing.","metaTitle":"Siemens 3VA2440-5HN32-0JH0 SENTRON MCCB, 400 A, 187 kA","metaDescription":"Siemens SENTRON 3VA2440-5HN32-0JH0 molded case circuit breaker, 400 A rated, 187 kA breaking at 240 V.
