It protects a 1P+N final subcircuit against overload, short-circuit, and earth leakage, with a Type B tripping characteristic.
This RCBO derates linearly as the panel interior warms: 9.5 A at 40 °C, 9 A at 50 °C, 8 A at 70 °C. If the distribution board sits in a hot mechanical room or under a roof, size the upstream protective device against the derated figure, not the 30 °C label.
Depth is 77 mm, installation depth 70 mm — verify the gland plate depth if the enclosure is shallow. IP20 with the distribution board installed and conductors connected; not rated for wet or dusty environments without an outer enclosure.
