Solutions for PV photovoltaics
VPU I and VPU II variants can be used in
photovoltaic systems in accordance with IEC
50539-11.
VPU I lightning and surge protection
Maximum type I protection from lightning and surges
With the increase in limit values in standards, the introduction of IEC/EN 61643-11 in 2012 places
great emphasis on the need for all-round, reliable surge protection.
Our response to these new requirements is the new VPU lightning and surge protection series.
Based on a combined varistor gas discharge technology, this forward-looking series of products is
currently the rst on the market to full the new international standards and will therefore give your
plant the highest protection.
However, you will not just be protecting your plant, but also your planning processes. Conformity
with standards for at least 5 years means that you can minimise your planning iteration steps and the
redesigns associated with them.
Many intelligent product features help installers during installation and maintenance specialists during
their servicing of the lightning and surge protection system.
Equipped in this way, the VPU series provides a long-lasting, safe and forward-looking lightning and
surge protection solution for your plant.
See for yourself.
Type I and II lightning arrester
Flexible positioning in the control cabinet
According to IEC 62305, the line path from the
surge protection module to the PE connection
may only be 50 cm. The fact that you can rotate
the base through 180° means that you have the
highest degree of exibility during installation,
without impacting on overall visibility.
