It carries a breaking capacity of 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V — figures that cover most industrial fault-current scenarios up to high-capacity distribution.
Above that, derate stepwise: 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, and 450 A at 70 °C. Maximum power loss is 162 W, so panel ventilation or spacing must account for that heat.
