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
