Surge protection for industrial buildings Production downtimes often incur high costs and effort. An appropriate surge protection concept increases the availability of production plants and systems. Moreover, without the appropriate lightning and surge protection, many systems are uninsured and are not issued an operating license. But what do I need to take into consideration when selecting the right protective devices?

Rendering of an industrial building with a view of the individual levels

Selecting the appropriate protective devices is not all that difficult. We have created a selection guide especially for industrial installations that clearly illustrates the appropriate protective devices for the respective installation locations.

You will find further information in the info papers. Here, we describe what you need to take into consideration when selecting the right backup fuse for SPDs. In the second info paper, you will learn what differentiates our special T1+T2 combined lightning current and surge arrester from other combined lightning current and surge arresters.
