The VPU series of lightning and surge protection products from Weidmüller is designed to fulfil the requirements of protection levels one, two and three for power networks.

As a result, the series is fully compliant with the current IEC 61643-11 and the future EN 61643-11 standard, which will be introduced in 2013.

The VPU series — based on a combination of varistor and gas discharge technology — incorporates around 200 variants and covers various protection zones and protection classes, making it suitable for applications ranging from facilities and building infrastructure through to machine construction, process equipment and renewable energy technology.

The series includes leakage-current-free type-one devices that offer excellent protection for use before the meter. Weidmüller also offers reliable type-three protection for all important end devices.

Key benefits

  • The VPU series is claimed to deliver sustainable protection for buildings and plant infrastructures.
  • It is said to offer users a high level of planning security and investment protection; this is because the series enables users to not only secure their facilities but their planning processes too.
  • Thanks to its conformity with standards dating back at least five years, users of the lightning and surge protection range can minimise the iterative steps for planning in accordance with the IEC61643-12 application standard and the associated redesigns.
  • According to Weidmüller, VPU customers will save on costly, time-consuming redesigns and planning iterations that are clouded by uncertainty.
  • Users do not need to re-address their existing plans after the three-year transition period from the EN standard to a national standard, as the VPU products have already been tested in line with the current requirements.
  • Each VPU module can be positioned in the cabinet in order to achieve the shortest route to lightning protection thanks to its 180° rotation; the lower part of the base module can be rotated by 180° and also allows for a good view into the cabinet.
