It provides earth leakage protection for the downstream circuit, tripping the connected breaker when it detects a fault current to ground. Rated at 25 A and 400/415 V AC, this 4-pole unit is intended for three-phase outgoing circuits in distribution boards. The 30 mA sensitivity covers standard personnel protection (shock) and fire prevention, while the Type A designation means it responds to both sinusoidal AC and pulsating DC residual currents — common on circuits with single-phase rectifiers, switch-mode supplies, or variable-speed drives. The trip is instantaneous — no intentional time delay — so it clears ground faults immediately. That makes it suitable for final subcircuits where fast disconnection is required, but coordination with upstream time-delayed RCDs needs checking if selectivity is a concern. The RCD connects to the iC60 MCB via screws on the load side, using tunnel-type terminals that accept 1 to 25 mm² rigid or 1 to 16 mm² flexible cable. IP20 rated on the body, IP40 inside a modular enclosure. Designed and tested to IEC 61009-1 and EN 61009-1 — the harmonized standards for RCDs with integral overcurrent protection (though this is an add-on unit, it's certified to the same family standard). Rated impulse withstand voltage 6 kV, insulation voltage 500 V AC.","metaTitle":"Schneider Electric A9W21425 Acti9 Vigi iC60 RCD, 4P 25A 30mA","metaDescription":"Schneider Electric A9W21425 Acti9 Vigi iC60 add-on RCD, 4 poles, 25 A rated current, 30 mA sensitivity, Type A, instantaneous.
