It protects a single pole plus neutral (1P+N) circuit, rated 25 A at 50 °C with a 30 mA earth-leakage sensitivity and a Type B tripping curve. The 10 kA breaking capacity (Icn at 240 V AC) covers the majority of residential and light commercial panelboard fault levels. Clip-on DIN rail mounting and screw-clamp terminals make it a direct swap into any Acti9 or similar modular enclosure.
The 25 A rated current at 50 °C is the continuous load it can carry without tripping — derate if ambient exceeds that. The 30 mA earth-leakage threshold is the standard for personal protection against indirect contact (IEC 61009-1). Thermal-magnetic trip technology combines a bimetal strip for overload protection and a solenoid for short-circuit. The limitation class 3 rating means it limits let-through energy during a fault, reducing stress on downstream wiring and devices. Integrated earth-leakage protection eliminates the need for a separate RCCB — one module, one DIN position.
It is intended as an outgoer in a distribution board — the final circuit breaker feeding a socket outlet, lighting circuit, or small appliance load. Wire stripping length is 14 mm top, 13 mm bottom. Torque to 3.5 N·m top, 2 N·m bottom. The toggle switch provides local ON/OFF indication and can be padlocked (Ø 4 mm padlock) for lockout/tagout.
