The A9V31263 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 (MCBs) to provide comprehensive earth‑leakage protection in final distribution circuits. Rated at 63 A with a sensitivity of 30 mA and instantaneous tripping, this unit offers fast and reliable disconnection in the event of a ground fault, greatly enhancing personnel safety and equipment protection against indirect contact. Its A‑SI type (Super Immunised) classification ensures high immunity to unwanted tripping caused by transient currents, such as those from lightning surges or switching events, making it particularly suitable for environments with frequent electrical disturbances. Operating at 230‑240 V AC (50/60 Hz) and compliant with both EN/IEC 61009‑1 and 61009‑2‑1 standards, the device is voltage‑independent, meaning it does not rely on the supply voltage for tripping, ensuring operation even in degraded grid conditions. The unit clips onto a DIN rail and connects directly to the MCB via screw terminals, simplifying panel assembly. With a compact 72 mm width (4 modular pitches) and a height of 91 mm, it fits neatly into standard distribution boards. The integrated trip indicator provides clear local signalling for rapid fault identification. The A9V31263 is built with halogen‑free plastic parts, is PVC‑free, and carries Green Premium compliance, reflecting Schneider Electric’s environmental stewardship. Its total lifecycle carbon footprint is quantified at 6 kg CO₂ eq., with a recyclability potential of 28%, and the product is eligible for take‑back at end‑of‑life.
