The 10 kA interrupting capacity per EN 60898 tells you it can safely clear a fault up to 10,000 A at 400 V AC — enough for most sub-distribution boards in commercial and light industrial panels. That dual AC/DC rating is a real time-saver when you're stocking one spare for both AC lighting and DC control power in the same cabinet.
The quick-assembly mounting system snaps onto the rail without tools. Combined terminals at both top and bottom let you feed through or loop out without extra accessories.
Environmental and compliance details
Halogen-free and silicon-free construction means no corrosive off-gassing in a fault — important for panels with sensitive electronics or in clean-room adjacent areas. The surrounding temperature influence table shows derating above 55 °C: max 95% humidity at 55 °C, dropping to 55% at 70 °C and 35% at 75 °C — relevant if the breaker lives near a heat source.
