That kind of interrupting rating is what you need when the transformer is big and the bolted-fault current is serious. ## Current derating and thermal reality The 630 A rating at 40 °C drops as the ambient climbs: 612 A at 45 °C, 593 A at 50 °C, 575 A at 55 °C, 557 A at 60 °C, 538 A at 65 °C, and 520 A at 70 °C. The maximum power loss is 164.5 W, so plan for the heat dissipation in the enclosure. ## Physical fit and integration notes The breaker measures 248 mm high by 138 mm wide by 110 mm deep. If you need remote status or trip indication, you'll add the auxiliary contact separately.","metaTitle":"Siemens 3VA2463-5HN32-0DA0 SENTRON MCCB, 630 A, 187 kA","metaDescription":"Siemens 3VA2463-5HN32-0DA0 SENTRON molded case circuit breaker, 630 A continuous, 187 kA breaking at 240 V.
