The 630 A rating holds at 40 °C ambient; step up to 50 °C and it derates to 593 A, at 60 °C to 557 A, and at 70 °C to 520 A. The breaker measures 110 mm deep by 138 mm wide by 248 mm tall, which fits the standard SENTRON 3VA fixed-mount footprint. Front face carries IP40 protection, so it's fine in a typical IP54 or IP55 enclosure as long as the gland plate seals the cable entries. This order code is listed as current production. The ETU350 trip unit is an electronic design, not the older thermal-magnetic platform.","metaTitle":"Siemens 3VA2463-8HN32-0AA0 SENTRON MCCB, 630 A, 3-Pole, ETU3","metaDescription":"Siemens 3VA2463-8HN32-0AA0 SENTRON molded case circuit breaker, 630 A continuous, 3-pole, ETU350 electronic trip unit.
