Schneider Electric Acti 9 iPRD Surge Protective Device Type 2+3 1P+N 8kA

The Schneider Electric Acti 9 iPRD surge protective device (SPD) is a high-performance Type 2+3 combined arrester designed to protect low-voltage electrical installations against transient overvoltages. Suitable for 1-phase + neutral (1P+N) networks, this compact DIN rail mounted unit provides both main and fine protection in a single device, simplifying installation and saving space.

Advantages

Combines Type 2 and Type 3 protection in one module, reducing the need for multiple devices. Features a removable cartridge for easy maintenance and a visual status indicator (green/red flag) for quick operational checks. Complies with IEC 61643-11 and EN 61643-11 standards, ensuring reliable performance.
