It protects a 1P+N final subcircuit against both overload/short-circuit (thermal-magnetic trip) and earth leakage, with a 10 mA sensitivity that catches even low-level leakage currents before they become a shock hazard or fire risk. Rated 6 A at 50 °C with a C-curve trip characteristic, it handles moderate inrush loads like small motors or lighting banks without nuisance tripping, while the 10 kA Icn breaking capacity at 230 V AC (50/60 Hz) means it can safely interrupt a fault current up to that level — enough for most residential and light commercial distribution boards.
Clip-on mounting to a standard DIN rail, occupying 2 x 9 mm pitches (18 mm total width). Torque to 2 N·m on the power circuit connections.
