Weidmüller’s new comprehensive 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.

As the damage statistics of property insurers have proved,  lightning and surge voltages can cause considerable damage to buildings and facilities. Facility operators need to protect their investments with innovative technologies and in accordance with the current standards – ultimately the costs to implement protective measures are only a fraction of the cost that could be incurred through damage.

 

Manufacturers and users of lightning and surge protection therefore redefined the requirements of a reliable protective system to protect assets and people, and in doing so,  influenced the existing IEC 61643-11 and future EN 61643-11 (in 2013) standards which apply to surge protection devices and products in the energy sector

Based on a combination of varistor and gas discharge technology, the VPU product series is primed for the future but already meets the conditions of the new international standards, so delivering sustainable protection for buildings and plant infrastructures.

The VPU series enables users to not only secure their facilities, but also their planning process.  Due 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.

Various practical product features 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 featured is a large central display window which visibly shows all the information regarding the status of the protection function.  In addition, 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.

It can be heard and felt when the vibration-resistant designed arrestor snaps onto the base and the remote signalling contact can also then be quickly and reliably connected using the “PUSH IN” connection system.
