Durable and powerful type-1 lightning current arresterPhoenix Contact’s Flashtrab SEC-PLUS type-1 lightning current arresters, which are particularly durable and powerful thanks to Safe Energy Control Technology, have just been complemented by two product variants.

The Flashtrab SEC-PLUS 440 product variant is particularly suited to special industrial applications with 440/690V networks or 400V power supply systems. The products impress with their strong shock and vibration resistance. This compact variant can be used up to 400A 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 backup fuse-free use up to 315A 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.
