The Schneider Electric Acti9 iPRD40 A9L040600 is a Type 2 surge protective device (SPD) engineered for 3P+N low-voltage installations. It is designed for high lightning-risk locations and incoming distribution panels, offering convenient replacement of damaged cartridges without dismantling the entire assembly. The device can be rotated so that phase, neutral, and earth cables enter from either the top or the bottom, simplifying wiring in diverse configurations. It is compatible with both TT and TN-S earthing systems. The associated circuit breaker must have a short-circuit breaking capacity of at least 50 kA. Key electrical ratings include a maximum discharge current (Imax) of 40 kA, a nominal discharge current (In) of 15 kA, and a voltage protection level (Up) of 1.4 kV in both common and differential modes. The maximum continuous operating voltage (Uc) is 260 V AC between neutral and earth, and 350 V AC between phase and earth as well as between phase and neutral. The rated service voltage is 230 V AC or 400 V AC, and the operating frequency is 50 Hz or 60 Hz. The unit measures 72 mm (W) × 85 mm (H) × 69 mm (D), occupies eight 9 mm pitches, and weighs 450 g. It provides IP20 terminal protection (IP40 when installed in a modular enclosure) and operates from -25 °C to +60 °C, with storage from -40 °C to +85 °C. Compliance with EN 61643-11 and IEC 61643-11 ensures reliable performance.
