The Flashtrab-SEC-T1+T2 protective device combination consists of line-follow-current-free type 1 lightning arresters on the basis of a spark gap and varistor-based type 2 surge protective devices. This combination, in just one device, is the only one on the market worldwide.
Thanks to Safe Energy Control technology (SEC), the products are durable and powerful. The load of the entire installation is reduced to a minimum in the event of lightning. The lightning arrester combination provides specific protection for installation environments with frequent switching operations. High lightning currents are safely controlled from the spark gap free of line follow current and temporary surge voltages are reliably limited by the varistors. The resulting low voltage protection level and fuse-free use in 230/400 V power supply systems are further advantages of this product range.
The compact arrester reduces the effort required for installation and maintenance. All products are pluggable and can be tested with the test device for the Checkmaster 2 surge protective devices.
