Weidmüller has recently introduced its new lightning and surge protection VPU series which 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.

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, and thus delivers sustainable protection for buildings and plant infrastructures.

By using the VPU series, facilities and planning processes can be secured. In addition, due to its conformity with standards dating back at least five years, users 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.

A large central display window shows all the information regarding the status of the protection function, and 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 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 connected using the ‘PUSH IN’ connection system.
