Continuous current derates with ambient temperature: 630 A at 40 °C, 612 A at 45 °C, 593 A at 50 °C, 575 A at 55 °C, 557 A at 60 °C, 538 A at 65 °C, and 520 A at 70 °C. For a 40 °C panel, the 630 A frame is the headline rating; above that, apply the derate curve. ## Physical fit and auxiliary options Panel cutout and mounting hole pattern should match the SENTRON 3VA series; verify against the existing backpanel layout. Maximum power loss is 162 W; operating temperature range -25 °C to 70 °C, storage -40 °C to 80 °C. The part carries a voltage trigger (yes) and a trip indicator (no) — the shunt trip provides remote tripping capability.","metaTitle":"SENTRON 3VA2463-6HN32-0KB0 MCCB, 630 A, 3-Pole, 242 kA at 24","metaDescription":"SENTRON 3VA2463-6HN32-0KB0 molded case circuit breaker, 630 A continuous, 3-pole, 242 kA breaking at 240 V.
