The A9V35463 is a four‑pole add‑on residual current device (RCD) from Schneider Electric’s Acti9 Vigi iC60 range, designed to be paired with Acti9 iC60 or Reflex iC60 miniature circuit breakers. It provides earth‑leakage protection for personnel and equipment in three‑phase AC installations, featuring a 300 mA sensitivity and a selective (time‑delayed) trip response that ensures discrimination with downstream RCDs. Its Type A‑SI (Super Immunised) classification delivers high immunity to nuisance tripping caused by harmonics, surges, and polluted or corrosive environments, while voltage‑independent technology guarantees reliable operation even during supply fluctuations. The device protects against indirect contact electric shock and fire hazards, and its VisiTrip indicator clearly shows the faulted circuit to speed up maintenance. With a compact 135 mm width (7 modules), DIN‑rail mounting, and a rated operational voltage of 230–415 V AC, it integrates easily into industrial, commercial, and tertiary distribution boards. The RCD is discontinued as of 23 September 2025.
