At 70 °C ambient the breaker is good for 520 A continuous. That's a 17 % reduction from the 40 °C figure — plan your fill factor around the worst-case ambient, not the catalog max. The breaker measures 248 mm high by 138 mm wide by 110 mm deep. The width at 138 mm means it occupies three 45 mm pole spaces on a DIN-rail adapter plate, standard for a 3-pole MCCB this size. Maximum power loss is 162 W at rated current. In a sealed stainless enclosure at 50 °C ambient, that heat load drives the derating curve above.","metaTitle":"Siemens 3VA2463-6HL32-0AE0 SENTRON MCCB, 630 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2463-6HL32-0AE0 molded case circuit breaker, 630 A continuous, 3-pole, line protection.
