The A9V31463 is a 4‑pole add‑on residual current device (RCD) from Schneider Electric’s Acti9 Vigi iC60 range, engineered to be mounted alongside Acti9 iC60 or Reflex iC60 miniature circuit breakers (MCBs) to provide comprehensive earth‑leakage protection in three‑phase AC installations. Rated at 63 A with a sensitivity of 30 mA and instantaneous tripping, this RCD delivers fast and reliable disconnection in the event of a ground fault, significantly reducing the risk of electric shock from indirect contact and mitigating fire hazards. Its Type A‑SI (Super Immunised) classification ensures high immunity against unwanted tripping caused by transient disturbances, such as lightning surges or switching operations, making it particularly suitable for electrically noisy or polluted environments. Operating at 400‑415 V AC (50/60 Hz) and compliant with IEC 61009‑1 and EN 61009‑1, the device employs voltage‑independent residual current detection, guaranteeing reliable operation even in degraded supply conditions. As an add‑on module, it clips onto a standard DIN rail and connects directly to the associated MCB via tunnel‑type screw terminals, simplifying 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 135 mm width (7 modular pitches) and low weight of 0.245 kg make it easy to integrate into three‑phase distribution boards, while the integrated trip indicator provides clear local fault signalling for rapid diagnostics. Environmentally, the device is built with halogen‑free plastic parts and is PVC‑free, with a total lifecycle carbon footprint of 8 kg CO₂ eq., though its recyclability potential is 28%. It carries Green Premium compliance with RoHS (by exemption) and REACh, and is marked for WEEE separate collection at end‑of‑life.
