At 690 V it's still good for 9 kA, so it handles mixed-voltage panels without a second breaker. Thermal derating is baked in: 630 A at 40 °C, 612 A at 45 °C, 593 A at 50 °C, and so on down to 520 A at 70 °C. Power loss maxes out at 162 W, so plan ventilation if you're packing a row of these. That depth — 110 mm — is the key number for shallow enclosures or when you're stacking breakers behind a gland plate.","metaTitle":"Siemens SENTRON 3VA2463-6HN32-0KH0 MCCB, 630 A, 242 kA at 24","metaDescription":"Siemens SENTRON 3VA2463-6HN32-0KH0 molded case circuit breaker, 630 A continuous, 242 kA interrupting at 240 V.
