The B-curve overcurrent trip (3.2 to 5 times In) protects against short-circuit and overload in resistive or lightly inductive circuits — typical for lighting, socket outlets, and small control transformers where inrush is modest.

Temperature derating — don't ignore it
At 40 °C it derates to 5.7 A, at 50 °C to 5.4 A, and at 70 °C to 4.62 A — if this RCBO sits in a crowded enclosure near other heat sources, size the load against the derated figure, not the 30 °C nameplate.
Mounting position is unrestricted — vertical, horizontal, or inverted — and supply can enter from either top or bottom.
