The A9V61263 is a 2‑pole add‑on residual current device (RCD) from Schneider Electric’s Acti9 Vigi iC60 family, engineered to be mounted alongside Acti9 iC60 or Reflex iC60 miniature circuit breakers for enhanced earth‑leakage protection in final distribution circuits. Rated at 63 A with a highly sensitive 30 mA tripping threshold and instantaneous response, this RCD provides rapid disconnection upon detection of residual currents, significantly reducing the risk of electric shock from indirect contact and mitigating potential fire hazards. Its Type A‑SI (Super Immunised) classification ensures robust immunity against nuisance tripping caused by transient disturbances, such as lightning strikes or switching surges, making it particularly well‑suited for electrically noisy or polluted environments. Operating at 230‑240 V AC (50/60 Hz) and fully compliant with IEC 61009‑1 and EN 61009‑1, the device utilises voltage‑independent residual current detection technology, guaranteeing reliable operation even under degraded or fluctuating supply conditions. The integrated VisiTrip window provides a clear visual indication of fault tripping, simplifying fault diagnosis and reducing downtime. As an add‑on module, it clips onto a standard DIN rail and connects directly to the MCB via tunnel‑type screw terminals, streamlining panel assembly and wiring. With IP20 protection at the terminals and IP40 when enclosed in a modular enclosure, it operates reliably across a wide temperature range from -25 °C to +60 °C. Designed with halogen‑free plastic parts and PVC‑free construction, this RCD carries Green Premium compliance, though its recyclability potential is rated at 28% with a total lifecycle carbon footprint of 6 kg CO₂ eq.
