Rated at 125 A (In) with a 1000 mA earth-leakage sensitivity, this 4-pole unit covers 230...415 V AC operational voltage. The Type A-SI (Super Immunised) classification means it handles pulsed DC residual currents and is immune to nuisance tripping from high-frequency leakage — common in drives and UPS-fed circuits. The residual current tripping technology is voltage independent, so the device still trips on earth fault even if the supply voltage is lost. The selective time delay coordinates with downstream RCDs — the Vigi C120 holds off long enough for the closer device to clear first, keeping the rest of the board live. Height is 95 mm, depth 73 mm. Tunnel-type terminals accept 1...35 mm² flexible or 1...50 mm² rigid cable; strip length 15 mm, tightening torque 3.5 N.m. Electrical connection to the upstream MCB is by screws. IP20 rated — suitable for enclosed distribution boards only, not washdown or outdoor exposure. Designed to EN 61009 and IEC/EN 61009-2-1. Rated insulation voltage 500 V AC 50/60 Hz per IEC 60947-1; rated impulse withstand voltage 6 kV per IEC 60947-2. Ambient operating range -25...60 °C; storage -40...60 °C. Mechanical durability 20 000 cycles.","metaTitle":"Schneider Electric A9N18561 Acti9 Vigi C120, 4P, 125A, A-SI,","metaDescription":"Schneider Electric A9N18561 Acti9 Vigi C120 add-on RCD. 4P, 125 A rated current, 1000 mA sensitivity, Type A-SI, selective.
