For a 400 A feeder you set the continuous pickup lower, but the breaker still clears a bolted fault at the full 121 kA at 415 V. Ambient derating is published per degree: 630 A at 40 °C drops to 520 A at 70 °C, which matches the maximum operating temperature of 70 °C. ## Built-in accessories and panel fit Dimensions are 110 mm deep, 138 mm wide, 248 mm high.","metaTitle":"Siemens 3VA2463-5HL32-0KF0 SENTRON MCCB, 630 A, 3-Pole, Line","metaDescription":"Siemens 3VA2463-5HL32-0KF0 SENTRON molded case circuit breaker, 630 A continuous at 40 °C, 3-pole, line protection.
