Product Features

- The Surge protective devices(SPDs), suitable for residential,commercial and industrial appications, are designed to limit transient overvoltage and run-off lightning currents.

- It provides reliable protection from the destructive effects of lightning and switching

overvoltages.

Function:

- are lightning current arrsters, they can handle and divert high energy from lightning.

-they are necessary when the installation is exposed to direct lightning(for example when the buiding is equipped with external lightning protection system or powered by aerial lines).
