That 10 A is the continuous thermal rating at 30 °C ambient; the magnetic trip responds to short-circuit currents above 50 A. The real differentiator here is the breaking capacity: 25 kA Icn (rated short-circuit capacity per IEC 60898) and 50 kA Icu (ultimate breaking capacity per IEC 60947-2). The Icn is the service breaking capacity — the breaker can clear a 25 kA fault and still be serviceable afterward. The Icu of 50 kA is the ultimate limit: it can safely interrupt that fault current once, but may need replacement after. For a 1-pole 10 A MCB, that's industrial-grade fault handling, not typical residential gear. The IP20 enclosure is standard for protected indoor panel mounting; the screw terminals accept up to 3.5 Nm torque for solid or stranded copper.
The 1-pole width is 27 mm, depth 82.5 mm, height 95 mm — fits a standard MCB slot in any distribution board. Screw terminals are front-accessible; the C-curve and rating are printed on the front face for quick identification during commissioning or swap-out.
