It provides earth-leakage protection for a 4-pole (4P) circuit rated at 63 A, with a 100 mA sensitivity and Type AC detection for sinusoidal AC fault currents. The unit is voltage-independent, meaning it trips on residual current alone without needing a separate power supply — a key reliability feature for downstream protection.
Mounts via clip-on onto a DIN rail, occupying 7 x 9 mm pitches (135 mm width total). The tunnel-type terminals accept 1–35 mm² rigid or 1–25 mm² flexible cable on the downside, with a tightening torque of 3.5 N·m and a wire stripping length of 14 mm. The electrical connection to the upstream MCB is by screws, making it a straightforward add-on for panel builders integrating into an Acti9 distribution board.
Rated operational voltage is 230/415 V AC at 50/60 Hz, with an insulation voltage of 500 V AC and impulse withstand of 6 kV per IEC 60947-2. Pollution degree 3 (conforming to IEC 60947-2) suits it for industrial control panels where conductive pollution may occur.
