“WOW” VARITECTOR PU Surge Protection Devices

Energy networks protect at the highest level
With VARITECTOR PU type I and II for 400/690 V systems


Production machinery and energy production plants are equipped with valuable technology. Of course you want to ensure that your investments are reliably protected, even if lightning strikes. The introduction of IEC/EN 61643-11 in 2012 with more stringent standard threshold values emphasises the high degree of relevance with regard to reliable surge protection.

Our response to these new requirements is the VARITECTOR PU lightning and surge protection series. Their new type-I and type-II variants are characterised by particularly high protection against lightning damage and coupling into industrial energy networks of up to 400/690 V base. The self-monitoring surge protection devices are available in 12.5 kA or 25 kA versions. The pluggable arresters enable particularly rapid replacement, while the proven locking mechanism ensures a firm hold.


Because of the sparkover gap and voltage ranges, the vibration-proof Type I and II models are ideal for the protection of 400/690 V systems in wind turbines.
