The 630 A continuous rating at 40 °C is the baseline; at 50 °C it derates to 593 A, at 60 °C to 557 A, and at 70 °C to 520 A. The interrupting curve is steep: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V. Maximum power loss is 162 W — account for that heat in the enclosure thermal calculation.
