Simple selection This simple example clearly demonstrates the advantages of the SEC range. Because it is not always easy to select the correct products for a given application in practice, this company offers customers a number of ways to learn more. The ‘Foundations of Surge Protection’ bro- chure provides a good introduction and a comprehensive overview. Starting with the way surge protectors work and going from there to explore various practical examples, all issues are clearly explained. All-in-one lightning and surge voltage protection The LT-SEC T1+T2 products combine • The powerful spark gap that is free of secondary power supply currents and discharges direct lightning currents emanating from the lightning protection systemor frompower lines, guaranteeing low residual voltage • The varistor arrester that effectively limits dynamic surge voltages thanks to its quick response characteristics • Optimal energy distribution between the protection levels depend- ing on the load occurring

• A basic prerequisite for optimal building protection is to ensure that every step has been taken to protect against surge voltage. • The SEC product range described in this article offers outstanding lightning and surge protection. • The product range allows multi-level protection for com- monly used installations and easy implementation.
