Product details

It carries a continuous current rating of 800 A at 40 °C, with derated values up to 70 °C (722 A at 70 °C). The 3-pole breaker delivers a breaking capacity of 187 kA at 240 V AC and 121 kA at 415 V, making it suitable for high-fault-current industrial mains or feeder circuits.

The 800 A rating holds flat from 40 °C to 50 °C, then derates linearly to 722 A at 70 °C. For a panel that runs at 55 °C ambient, the usable current is 780 A — enough headroom for most 600 A feeder designs. Dimensions are 320 mm high × 210 mm wide × 120 mm deep.
