It carries a C-curve tripping characteristic — meaning it holds through moderate inrush (5–10× rated current) before tripping magnetically, which suits motor starter and small transformer loads where the magnetic trip must not nuisance-trip on startup. The breaker is rated 10 kA breaking capacity per EN 60898 at 400 V AC, and 15 kA per IEC 60947-2, so it handles fault currents typical of a sub-distribution board without cascading upstream.
Environmental and compliance details
The enclosure is IP20 with connected conductors (IP40 in the handle area), so it's not washdown-rated but fine for a clean panel interior. Vibration resistance is 50 m/s² at 25–150 Hz and 60 m/s² at 35 Hz for 4 seconds — enough for machine-mounted panels near rotating equipment.
Rated voltage: 400 V AC / 60 V DC. Rated frequency: 50 Hz. Insulation voltage (Ui): 440 V AC.
