Its breaking capacity scales with system voltage: 121 kA at 240 V AC, 75.6 kA at 415 V AC, 52.5 kA at 440 V AC, 17 kA at 500 V AC, and 11.9 kA at 690 V AC — meaning it can clear faults up to those levels without upstream coordination issues at the respective voltages.
Above that, it derates linearly: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C.
