It protects a 1P+N final subcircuit against overload, short-circuit, and earth leakage, with a Type A residual-current sensor that catches pulsating DC fault currents as well as sinusoidal AC. The tripping characteristic is C (magnetic release between 5 and 10× In), and the unit is rated 13 A at 30 °C ambient, derating to 10.01 A at 70 °C.
The 13 A rating at 30 °C is the headline current; at 40 °C it drops to 12.48 A, at 50 °C to 11.96 A, and at 70 °C to 10.01 A. The Type A residual-current sensor means it trips on AC faults and on pulsating DC up to 6 mA — essential for circuits feeding single-phase rectified loads like switched-mode power supplies, LED drivers, or variable-speed drives with small front ends.
Snaps onto standard 35 mm DIN rail, occupies 2 module widths (36 mm wide, 77 mm deep, 90 mm tall). Installation depth is 70 mm — the extra 7 mm is the front projection of the toggle and test button. Mounting position is any, so horizontal DIN-rail orientation in a shallow enclosure is fine.
