Product Description

The Schneider Electric Acti9 iPRD1 F25r (A9L1F325) is a high-performance Type 1+2 surge protective device designed to safeguard industrial and tertiary electrical installations against direct lightning strikes and transient overvoltages. Its integrated surge-adapted backup fuse enhances system safety and reliability.

This 3-pole modular SPD is specifically designed for TN-C earthing systems and features pluggable cartridges for rapid replacement, helping to minimise downtime during maintenance. A clear front-facing status indicator shows green when operational and red when cartridge replacement is required.

Remote signalling contacts allow the device status to be monitored externally, making it ideal for critical power systems and main distribution boards. The compact DIN-rail mounting design ensures efficient use of space while delivering powerful surge and lightning protection.
