Product Description

The Schneider Electric Acti9 iPRD1 F25r (A9L1F625) is a high-capacity Type 1+2 surge protective device designed to protect industrial and tertiary electrical installations from direct lightning strikes and transient overvoltages. Featuring an integrated surge-adapted backup fuse, it delivers enhanced safety and continuity of service.

This 3-pole plus neutral (3P+N) modular SPD is equipped with pluggable cartridges for fast replacement, reducing maintenance time and system downtime. It provides both local visual status indication, via a green/red flag, and remote signalling for integration with monitoring systems.

Compatible with TT and TN-S earthing systems, the device offers exceptionally high discharge performance, making it ideal for main distribution boards in demanding environments. Its compact DIN-rail mounting design allows efficient use of space while delivering robust surge and lightning protection.
