It breaks fault currents up to 10 kA per EN 60898 and 20 kA per IEC 60947-2, making it suitable for final circuits in residential and commercial distribution boards where both overcurrent and earth leakage protection are required in a single 2-module-width (36 mm) package.
Rated current derating over temperature
At 40 °C the continuous current drops to 23.5 A, at 50 °C to 21.75 A, and at 70 °C to 18.25 A. For a panel running warm — say 45 °C internal ambient — the usable rating is 22.75 A, not the 25 A on the label. Plan the load accordingly.
Mounts in any position, accepts supply from top or bottom. Installation depth is 70 mm; the device itself is 77 mm deep, 36 mm wide (2 modular units), 90 mm tall. Rated IP20 with the distribution board installed and conductors connected. Halogen-free and silicon-free construction.
