Product description
The DEHNrail Type 3 surge arresters are designed for fine protection of terminal equipment, providing the final level of surge protection close to sensitive electrical and electronic devices.
Installed directly at the point of use, DEHNrail devices limit residual voltages that remain after upstream Type 1 and Type 2 protection. This makes them an essential part of a coordinated surge protection concept for commercial, industrial, and infrastructure installations across Ireland.
