It integrates a 10 A thermal-magnetic trip unit (C-curve, magnetic trip 5–10 × In) with 300 mA earth-leakage detection, so one device handles both overload/short-circuit and ground-fault protection on a single-phase outgoing circuit. Rated breaking capacity is 6000 A Icn at 230 V AC, 50/60 Hz, conforming to EN/IEC 61009-2-1. Limitation class 3 means it restricts let-through energy enough to coordinate with downstream loads in a distribution board.
Clip-on mounting to DIN rail, 36 mm width (4 × 9 mm pitches), neutral on the left. Depth 73 mm, height 85 mm. Tunnel terminals top and bottom accept 1–16 mm² rigid or 1–10 mm² flexible; strip length 14 mm, tighten to 2 N·m.
