VPU surge voltage protection, presented by Weidmüller

Weidmüller is offering a new, convincingly designed lightning and surge protection VPU series that provides planning security and investment protection. Thanks to its comprehensive VPU product range in accordance with types 1, 2 and 3 for energy networks, Weidmüller leaves nothing to be desired and provides the answers to the current IEC 61643-11 and the future EN 61643-11.

The EU standard to be introduced in 2013 emphasises the high degree of relevance with regard to reliable lightning and surge voltage protection. Based on a combination of varistor and gas discharge technology, the VPU product series is primed for the future but already fulfils the new international standards, so it offers your facilities sustainable protection.

The VPU series enables users to not only secure their facilities but also their planning process: Thanks 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. There are also various practical product features to support installers and maintenance specialists when working with or servicing the lightning and surge protection systems.

Each VPU module can be positioned in the cabinet in order to achieve the shortest route to lightning protection equipotential thanks to its 180° rotation. Also featuring a large centred status window visibly displays all the information on the protection function. A new mounting rail clip makes installation easier as it can be operated without tools. It is fast to dismount - even from a module group - by simply pulling back the clip-in foot.

The innovative mechanics of the clip-in foot ensure the precise removal of the VPU module from the mounting rail. You can hear and feel when the vibration-resistant designed arrestor snaps onto the base. Even the remote signaling contact can be quickly and reliably connected using the "PUSH IN" connection system. It provides reliable information regarding the status of the protection function.
