Surges can be caused, for example, by lightning striking your premises. Lightning induces voltage surges in conductors and cables that can damage any connected equipment. Also switching in households, for example with luroescent lamps and conventional ballast, can cause surges in the buildings wiring system. Effective protection provides AEG‘s surge protector series.Protect your sensitive equipment and save standby costs.
