The breaking capacity at 240 V is 187 kA, at 415 V it's 121 kA, at 440 V it's 36 kA, and at 690 V it's 17 kA — those numbers tell you the fault current it can safely interrupt at each voltage level, which governs selectivity coordination downstream.
Above that it derates: 155.6 A at 55 °C, 151.2 A at 60 °C, 146.8 A at 65 °C, and 142.4 A at 70 °C. If your panel runs hot, the real continuous current you can pull is lower than the nameplate Iu — size the load accordingly.
