Product Description

The Schneider Electric Acti9 iPRD1 C25r (A9L1C325) is a robust Type 1+2 surge protective device designed to safeguard three-phase electrical installations from direct lightning currents and transient overvoltages. It is ideally suited to industrial and tertiary environments requiring high surge discharge capability.

This 3-pole modular SPD uses gas discharge tube (GDT) technology and is designed for TN-C earthing systems. It features pluggable cartridges for rapid maintenance, minimising downtime and ensuring continuity of service. A clear front-facing status indicator displays green during normal operation and red when replacement is required.

The device includes remote signalling contacts for external monitoring and is intended for use with an associated 315A gG upstream fuse. Its compact DIN-rail mounted design helps maximise space within distribution boards while delivering powerful surge and lightning protection.
