Its D tripping characteristic (10–20× In magnetic trip) handles high inrush loads like motor starters, transformers, and welding equipment without nuisance tripping on startup. Rated 10 kA breaking capacity per EN 60898 and 15 kA per IEC 60947-2 at 400 V AC, it clears faults up to those levels without cascading upstream. The 2-pole design switches both phase conductors; the neutral is not switched (no neutral pole).
The IP20 rating (IP40 in the handle area with conductors connected) means it lives inside a cabinet, not exposed to washdown. Vibration resistance to 50 m/s² at 25–150 Hz and 60 m/s² at 35 Hz (4 s) keeps it functional on machinery with moderate vibration.
