Above that, the device derates linearly: 115.62 A at 40 °C, 111.25 A at 45 °C, 106.25 A at 50 °C, 101.25 A at 55 °C, and 96.25 A at 60 °C. If your panel ambient runs 50 °C, you're limited to 106.25 A continuous — that's the number to put in your load schedule, not the 125 A headline.
Installation depth is 70 mm. The housing is IP20 once installed in a distribution board with conductors connected.
