It protects a single-phase outgoer (1P + Ns, neutral left) against overload, short-circuit, and earth leakage in one unit, saving a DIN-rail position compared to separate MCB + RCCB. Rated 40 A at 50 °C with a C curve, 30 mA earth-leakage sensitivity. Compliant with IEC 61009-1 and IEC 61009-2-2. Breaking capacity is 10 kA Icn at 240 V AC 50/60 Hz, limitation class 3, meaning it limits let-through energy enough for most final-distribution panels with a downstream fault. The thermal-magnetic trip unit is sealed — no field adjustment.
The modular enclosure carries IP20 (IP40 in the enclosure) — suitable for dry indoor panels. Padlockable with a Ø 4 mm padlock for lockout/tagout. Screw-clamp terminals: top accepts 1…25 mm² rigid or 1…16 mm² flexible; bottom accepts 1…16 mm² rigid or 1…10 mm² flexible. Tightening torque 3.5 N.m top, 2 N.m bottom. Strip length 14 mm top, 13 mm bottom.
