Its breaking capacity reaches 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 6.3 kA at 690 V — these are the maximum fault currents it can safely interrupt at each voltage level.
The breaker carries 250 A continuously up to 50 °C ambient. Above that, it derates linearly: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. Maximum power loss is 48 W. The 86 mm depth, 105 mm width, and 181 mm height fit standard panel layouts — verify gland plate clearance for the 105 mm width when retrofitting into an existing cutout.
