Full compliance

Weidmüller's new 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 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 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. Each VPU module can be positioned in the cabinet to achieve the shortest route to lightning protection equipotential thanks to its 180° rotation.
