The thermal derating curve is published from 40 °C (630 A) through 70 °C (520 A), so you can size it for a warm enclosure without guessing.","metaTitle":"Siemens 3VA2463-7HN32-0KA0 SENTRON MCCB, 630 A, ETU350, 330","metaDescription":"Siemens SENTRON 3VA2463-7HN32-0KA0 molded case circuit breaker, 630 A continuous, ETU350 electronic trip, 330 kA interrupting at 240 V.
