Durable, powerful lightning current arrester

October 2015 Electrical Power & Protection

The durable and powerful Flashtrab SEC-PLUS type 1 lightning current arresters from Phoenix Contact have been complemented by two product variants. The Flashtrab SEC-PLUS 440 variant is particularly suited to special industrial applications with 440/690 V networks or 400 V power supply systems. The products impress with their strong shock and vibration resistance. This compact variant can be used up to 400 A without an additional backup fuse.

The Flashtrab SEC-PLUS 350 variant is used in the pre-metering area of the main feed, or in industrial applications. High voltage fluctuations and lightning current loads are no problem for the type 1 arrester. The good protection level and fuse-free backup up to 315 A deliver additional advantages.

Both variants are pluggable and can be tested with the CheckMaster 2 test instrument for surge protection devices. Like any other SEC family type 1 arrester, the Flashtrab SEC-PLUS devices are also type 2 arrester tested and certified. The protective devices of the SEC product family have been completely redeveloped and are based on Safe Energy Control Technology (SEC). The spark gap safely prevents any power supply secondary current. This means that the load of the entire instal­lation is reduced to a minimum in the event of a lightning event.
