The 630 A rating is at 40 °C; above that, the thermal derating curve drops to 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, and 450 A at 70 °C. Maximum power loss is 162 W — account for that heat in the enclosure ventilation calculation. Dimensions are 110 mm depth, 138 mm width, 248 mm height (4.33 x 5.43 x 9.76 in). Verify the cutout against your existing backpan — the 138 mm width is the same as other 630 A SENTRON frames, so a panel built for a 3VA2 630 A breaker accepts this one without rewiring. ## Coordination and selectivity notes The minimum short-circuit setting is 945 A, maximum 5 670 A — adjust the magnetic trip to avoid nuisance tripping on motor inrush while still clearing a bolted fault. No undervoltage release or voltage trip is fitted on this variant, so it stays closed through a sag unless you add an external shunt trip.","metaTitle":"Siemens 3VA2463-5KQ32-0AA0 SENTRON MCCB, 630 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA2463-5KQ32-0AA0 molded case circuit breaker, 630 A rated, 3-pole, line protection.

The 3VA2463 is 138 mm wide vs the 3VA2225's narrower width, so the mounting holes and busbar spacing do not align.
