Interference voltages, such as those that occur as a result of switching operations or lightning strikes, are all relatively high in energy. It is essential that you protect your systems with powerful lightning and surge protective devices.

Your advantages

  • Protection for all common applications and signals, thanks to the complete product portfolio
  • Versatile fields of application – designs and connection methods for every application
  • Space-saving and inexpensive installation, thanks to narrow design
  • Easy testing, thanks to plug-in arresters

The protective circuit principle

The protective circuit against surge voltages  

The protective circuit against surge voltages

An "effective protective circuit" helps to implement seamless surge protection.

And this is how it works:

Draw an imaginary circle around the object you want to protect.

Surge protective devices must be installed at all points where cables intersect this circle.

The area within the protective circuit is therefore protected in such a way that conducted surge voltages are prevented.

Consider the following areas during planning:

  • Power supply
  • Measurement and control technology
  • Data processing, telecommunications
  • Transceiver devices
