Product Description

The Schneider Electric Acti9 iPRD1 C25r (A9L1C625) is a high-performance Type 1+2 surge protective device designed to protect three-phase electrical installations in industrial and tertiary buildings from direct and indirect transient overvoltages, including lightning currents.

This 3P+N modular surge arrester features pluggable cartridges for rapid replacement and includes both local and remote status indication. A front-mounted visual flag shows green during normal operation and red when cartridge replacement is required, while the remote contact allows external monitoring of device status.

Compatible with TT and TN-S earthing systems, the device operates at 230/400V AC and delivers extremely high discharge capacity. It is designed to be used in conjunction with an associated 315A gG fusible disconnect device. The compact DIN-rail mounted design helps maximise space within distribution boards.
