Thermal derating is published across the full ambient range: 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 panel that runs warm — say 50 °C inside the enclosure — the breaker is good for 593 A continuous, not the full 630 A. That derating curve is the number to use for NEC ampacity calculations, not the 40 °C nameplate. The adjustable trip range spans 945 A minimum to 5 670 A maximum, giving selectivity headroom downstream. Maximum power loss is 162 W at rated load — relevant for enclosure thermal management if the breaker is in a sealed cabinet with other heat sources. The basic switch is order code 3VA2463-6HL32-0AA0. ## Panel integration — dimensions and environment Footprint: 138 mm wide, 248 mm high, 110 mm deep. Mounts in a standard distribution panel or MCC bucket; the 138 mm width is three 45 mm pole pitches, so it occupies the same space as a typical 3-pole frame.","metaTitle":"Siemens 3VA2463-6HL32-0KL0 SENTRON MCCB, 630 A, 3-Pole, 242","metaDescription":"Siemens SENTRON 3VA2463-6HL32-0KL0 molded case circuit breaker, 630 A continuous at 40 °C, 3-pole, breaking capacity 242 kA at 240 V.
