Type-1 lightning current arrester

06 October 2015

The Flashtrab SEC-PLUS type-1 range of lightning current arresters from Phoenix Contact, which incorporate Safe Energy Control Technology (SEC) to ensure durability, has been complemented by the addition of two new product variants. SEC technology ensures that the spark gap safely prevents any power supply secondary current so that the load of the entire installation is reduced to a minimum in the event of a lightning event.

The Flashtrab SEC-PLUS 440 is suited to industrial applications with 440/690-V networks or 400-V power supply systems. The compact products are said to offer strong shock and vibration resistance. This variant can be used up to 400 A without an additional backup fuse.

The Flashtrab SEC-PLUS 350 type-1 arrestor is designed for use in the pre-metering area of the main feed, or in industrial applications. It is able to handle high voltage fluctuations and lightning current loads. 

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.
