It combines two protection functions in one DIN-rail module: series arc fault detection per EN/IEC 62606 and residual current protection per EN/IEC 61009-1 and EN/IEC 61009-2-1, with a rated current of 40 A and an earth-leakage sensitivity of 30 mA (Type A-SI, Super Immunised). The 30 mA sensitivity means it trips on ground faults that could harm personnel, while the Super Immunised designation prevents nuisance trips from high-frequency inverter noise or transient surges common on modern industrial lines. The overvoltage trip threshold is set at 275 V ±5 V, protecting downstream equipment from sustained voltage swells. Measurement accuracy is ±2 % for voltage and current, ±5 % for active power, which is sufficient for energy monitoring and fault logging via the compatible EcoStruxure Panel Server concentrators.
Clip-on mounting on DIN rail, occupying 2 x 9 mm pitches. Neutral is on the left. Operating altitude is rated to 2000 m; storage temperature range is -40 to 85 °C with tropicalisation severity B per IEC 60068-2-30 for 28 days, meaning it handles humidity cycling in non-condensing panel environments. Local signalling includes ON, OFF, and fault-trip LED indicators plus an arc fault diagnostic LED. Event management covers overvoltage, earth leakage, and overload events with date-and-time recording and maintenance indicators. This is an outgoer device — intended for final subcircuit protection, not incoming main switch duty.
