A surge protection device (or surge suppressor or surge diverter) is an appliance or device designed to protect electrical devices from voltage spikes. A surge protector attempts to limit the voltage supplied to an electric device by either blocking or shorting to ground any unwanted voltages above a safe threshold.
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 which can reach up to 6000 Volts.
Overvoltage can arise from lightning activity or switching transients generated from within a building, although these effects tend to be of a lower magnitude.
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 (TNS/TNC).
- 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.
