Surge Protection

A surge protection device is an appliance or device designed to protect electrical devices from voltage spikes. A surge protector limits the voltage supplied to an electric device by shorting to ground any unwanted voltages.

Surges or transients are short duration increases in voltage measured between two or more conductors. These potentially harmful voltages can be induced into a building from a direct strike or from secondary effects of lightning.

Overvoltage can arise from lightning activity or switching transients generated from within a building.

As a general guide, all cables that enter or leave a building should be protected as these lines offer electricity pathways in.

  • Featuring a pluggable surge protection module, the SPM series of arresters are ideally suited for most industrial applications.
  • The pluggable aspect allows the replacement of modules without having to disconnect cabling.
  • The units are rated at class 2 protection levels (8/20µs) and can be configured in various formats to cater for most earthing systems.
  • Have a DIN rail with each module being DIN width the placement of arresters in a consumer unit or Type B Distribution Boards are easily achieved.
