Rated breaking capacity hits 10 kA per IEC 60898-1 at 400 V AC, and 15 kA per IEC 60947-2 at 60 V DC — so it handles fault current on industrial lighting panels, small motor branch circuits, and DC control bus feeds. Also carries a UL 1077 / CSA C22.2 No. 235 supplementary protector rating at 5 kA for North American panels.
Mounts in any position. IP20 with conductors connected, pollution degree 3, overvoltage category III. That means it's rated for inside a standard industrial enclosure, not for wet or outdoor locations. Neutral conductor is not switched — it's a 2-pole breaker switching both phases (line and load), not line + neutral. Suitable for mechanical engineering and industry per the suitability listing.
Environmental limits and service life
Operates from -40 °C up to 75 °C ambient. Vibration tested per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. Mechanical service life typical 10,000 cycles. Halogen-free and silicon-free construction.
