This is a line-protection design — meaning it's intended for feeder or main breaker duty, not motor branch-circuit protection where a different trip curve would be needed. The 630 A rating is the continuous current at 40 °C ambient; the thermal derating table shows it carries 612 A at 45 °C, 593 A at 50 °C, and drops to 520 A at 70 °C — so if the panel ambient runs hot, the effective ampacity is lower than the nameplate figure. Breaking capacity is the other headline number: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 9 kA at 690 V.
Panel integration — dimensions and mounting
The 3VA2463-7HN42-0AA0 measures 248 mm high by 184 mm wide by 110 mm deep. That 184 mm width for a 4-pole frame is standard for the 3VA2 platform — it occupies the same footprint as other 4-pole units in the series.
The lifecycle stage is listed as current — meaning the manufacturer continues to produce this order code without a phase-out notice. No successor has been assigned.
