Surge voltage protection from Weidmüller
Weidmüller’s new comprehensive lightning and surge protection VPU series fulfils requirements for protection levels 1, 2 and 3 for power networks. This means full compliance with the current IEC 61643-11 and the future EN 61643-11 standard being introduced in 2013.
Based on a combination of varistor and gas discharge technology, the VPU product series is primed for the future but already meets the conditions of the new international standards. Due to its conformity with standards dating back at least five years, users of the new VPU lightning and surge protection can minimise the iterative steps for planning in accordance with the application standard IEC61643-12 and the associated re-designs.
Various practical product features support installers and maintenance specialists. Each VPU module can be positioned in the cabinet in order to achieve the shortest route to lightning protection equipotential thanks to its 180 degree rotation.
A large central display window shows all the information regarding the status of the protection function and a new mounting rail clip makes installation easier as it can be operated without tools.
