It protects a single-phase final subcircuit against overload, short-circuit, and earth leakage. Rated 6 A at 30 °C ambient, it derates to 4.62 A at 70 °C — a curve worth noting if the distribution board runs hot. IP20 applies once the board is closed with conductors connected.
Temperature derating and real-world current
The 6 A rating at 30 °C is the headline number, but the derating table tells the real story for a warm panel: 5.7 A at 40 °C, 5.4 A at 50 °C, 5.1 A at 60 °C, 4.86 A at 65 °C, and 4.62 A at 70 °C.
