That interrupting rating drops to 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V — so for a 480 V panel the available fault current must stay under 187 kA to maintain full coordination. ## Thermal derating — the real ampacity in a warm panel At 45 °C it derates to 612 A, at 50 °C to 593 A, at 55 °C to 575 A, at 60 °C to 557 A, at 65 °C to 538 A, and at 70 °C to 520 A.","metaTitle":"Siemens 3VA2463-7HN32-0AE0 SENTRON MCCB, 630 A, 330 kA at 24","metaDescription":"Siemens SENTRON 3VA2463-7HN32-0AE0 molded case circuit breaker, 630 A, 3-pole, ETU350 release, 330 kA at 240 V.
