It carries a 10 A rated current at 30 °C with a C tripping characteristic (magnetic release at 5–10× In), and a 300 mA Type A residual-current trip that catches sinusoidal AC and pulsating DC fault currents.
Temperature derating and real-world current
At 40 °C it derates to 9.5 A, at 50 °C to 9 A, and at 70 °C to 8 A. If the distribution board runs warm — say 50 °C inside the enclosure — the continuous load should be capped at 9 A to avoid nuisance tripping. The device is rated for any mounting position, which simplifies panel layout, and the supply can enter from top or bottom.
