The 3VA2463-7HL32-0BH0: The 330 kA breaking capacity at 240 V drops to 242 kA at 415 V and 440 V, then to 187 kA at 500 V, and 9 kA at 690 V. This is a high-interrupting rating for a 630 A frame — it clears severe fault currents without cascading upstream, which simplifies coordination studies in large distribution panels. The minimum short-circuit setting is 945 A, and the maximum is 5 670 A.
The 630 A rating holds at 40 °C; above that, derate linearly: 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. Maximum power loss is 164.5 W.
