The 6 kA breaking capacity per EN 60898 tells you it can safely interrupt a fault up to 6,000 A at 440 V AC without welding its contacts or cascading failure upstream. That standard certifies it for household and similar installations; for industrial panel SCCR coordination you'd check the upstream device's let-through. Rated current derates with ambient temperature: 15.04 A at 40 °C, 14.54 A at 45 °C, 13.47 A at 55 °C. The 3-pole design switches all phases; neutral is not switched.
Integration notes
Depth behind the panel is 70 mm installation depth; overall depth is 76 mm.
