The 10 kA breaking capacity, certified to both EN 60898 and IEC 60947-2, tells you it can safely interrupt a fault current up to 10,000 A at 400 V without welding its contacts or cascading upstream. That's the figure that governs selectivity coordination with the upstream device. Operating temperature spans -40 to 75 °C, covering unheated utility rooms and outdoor enclosures in cold climates.
