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.
