The A9V65263 is a 2‑pole add‑on residual current device (RCD) from Schneider Electric’s Acti9 Vigi iC60 range, designed to be mounted alongside Acti9 iC60 or Reflex iC60 miniature circuit breakers to provide comprehensive earth‑leakage protection in final distribution circuits. Rated at 63 A with a sensitivity of 300 mA and a selective (time‑delayed) tripping characteristic, this unit is specifically intended for fire protection and discrimination applications where a time‑graded coordination scheme is required – the selective delay ensures that downstream RCDs trip first, leaving this device to operate only for persistent faults, thereby minimising disruption to critical processes. Its Type A‑SI (Super Immunised) classification provides exceptional immunity against unwanted tripping caused by transient disturbances, such as lightning surges, switching operations, or polluted and corrosive environments, making it ideal for harsh industrial and outdoor installations. Operating at 230‑415 V AC (50/60 Hz) and fully compliant with IEC 61009‑1 and EN 61009‑1, the device employs voltage‑independent residual current detection technology, guaranteeing reliable operation even under degraded or fluctuating supply conditions. 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. The unit offers IP20 protection at the terminals and IP40 when housed in a modular enclosure, with a wide operating temperature range from -25 °C to +60 °C. Its compact 72 mm width (4 modular pitches) and low weight of 0.165 kg make it easy to integrate into distribution boards, while the integrated trip indicator provides clear local fault signalling. 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 5 kg CO₂ eq.
