At 630 A continuous, the power loss hits 192.9 W maximum — that's heat you need to vent in the enclosure. ## Thermal derating — where the 630 A holds and where it drops At 55 °C it derates to 618 A, at 60 °C to 607 A, at 65 °C to 595 A, and at 70 °C to 583 A. If your panel ambient runs hot — say, near a transformer or in a non-conditioned enclosure — the 55 °C to 70 °C band is where you lose roughly 2% to 7.5% of the rating. ## Panel fit — dimensions and IP rating The 3VA1463-5GE42-0AA0 measures 248 mm high, 184 mm wide, and 110 mm deep — a 4-pole frame that needs a 7.24-inch wide cutout in the panel door.","metaTitle":"Siemens 3VA1463-5GE42-0AA0 SENTRON MCCB, 630 A, 4-Pole, 187","metaDescription":"Siemens SENTRON 3VA1463-5GE42-0AA0 molded case circuit breaker, 630 A fixed rating, 4-pole, TM220 release.
