It carries a breaking capacity of 187 kA at 240 V and 121 kA at 415 V and 440 V, tapering to 7.5 kA at 690 V — that means it can safely interrupt massive fault currents at common distribution voltages without the arc escaping the case.
Above that it derates linearly: 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C — the maximum operating temperature. Minimum operating temperature is -25 °C. If you're packing this into a hot panel next to transformers or drives, the 55 °C derating point is the one to watch.
Built-in accessories and communication
It also includes a communication function, so it can talk to a PLC or BMS for remote trip indication and load monitoring. Power loss at full rated current is 98.5 W, worth factoring into panel ventilation calcs.
The case dimensions are 248 mm tall, 138 mm wide, and 110 mm deep.
