Integrator note — 3VA2463-7HL32-0JH0
The Siemens SENTRON 3VA2463-7HL32-0JH0 is a 3-pole molded case circuit breaker rated for 630 A continuous at 40 °C ambient, with a frame size that fits a 110 mm depth, 138 mm width, and 248 mm height envelope. The interrupting ratings are the headline: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 9 kA at 690 V.
Thermal derating and continuous current
At 45 °C it carries 612 A; at 50 °C, 593 A; at 55 °C, 575 A; at 60 °C, 557 A; at 65 °C, 538 A; at 70 °C, 520 A. If your enclosure ambient runs above 40 °C — common in a packed MCC lineup — the 630 A nameplate is not the usable number. The 70 °C derated figure of 520 A is what governs in a hot panel. Maximum power loss is 162 W, which matters for ventilation planning in a sealed cabinet.
Auxiliaries and releases
If you need UVR or GF protection, this is the wrong variant — you'd step to a different suffix.
Panel integration
Mounts in a standard switchboard or MCC bucket. Depth of 110 mm and width of 138 mm fit most 600 mm wide vertical sections with room for cable bending radius. The 248 mm height is compact for a 630 A frame — allows stacking in a multi-tier lineup. No communication function onboard, so any remote monitoring requires external I/O or a separate communication-capable breaker.
