Its breaking capacity hits 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V — numbers that tell you this unit handles high-fault-current industrial distribution panels, not just branch circuits. Front IP40 protection keeps out tool drops and dust during installation; the enclosure is rated for operation from -25 °C to 70 °C and storage from -40 °C to 80 °C, covering most indoor industrial environments.
Current derating across temperature
At 55 °C it derates to 24 A, at 60 °C to 23.5 A, at 65 °C to 23 A, and at 70 °C to 22.5 A. If the panel sits near a heat source or in a non-ventilated enclosure, check the actual ambient at the breaker — a 25 A continuous load at 65 °C would need the next frame up.
