The continuous current derates from 630 A at 40 °C to 450 A at 70 °C in 5 °C steps; at 50 °C the breaker is good for 570 A, at 60 °C for 510 A. ## Physical Fit and Auxiliary Switching","metaTitle":"Siemens 3VA2463-6KP32-0AH0 SENTRON MCCB, 630 A, 3-Pole, 242","metaDescription":"Siemens SENTRON 3VA2463-6KP32-0AH0 molded case circuit breaker, 630 A continuous, 3-pole, 242 kA breaking capacity at 240 VAC.
