It protects a single-phase outgoing circuit (1P+N) against overload, short-circuit, and earth leakage, all in one DIN-rail footprint. Rated 45 A at 50 °C with a 30 mA earth-leakage sensitivity and a Type C tripping curve, it's the sort of part that keeps a panel builder from having to stack a separate RCD and MCB on the same rail.
If your panel runs hotter, you'll need to derate. The integrated 30 mA earth-leakage protection provides personnel protection per IEC 61009-1, catching ground faults before they become a shock hazard.
Clip-on mounting to a 45 mm grid DIN rail. IP20 finger-safe protection means it's intended for enclosed panels, not washdown environments. The toggle switch gives local ON/OFF indication, and it's padlockable with a 4 mm hasp for lockout/tagout.
