With the increase in specification limits, the introduction of the standard IEC/EN 61643-11 in 2012 emphasizes the high level of importance related to the complete protection against power surges.
Our response to these new requirements is the new series VPU protection against lightning and voltage surges Weidmuller
Based on the combined technology of surge arrester gas and varistor, this series of products Weidmuller highly advanced already complies to the new standard and thus offers your facilities the greatest degree of protection.
This protection, however, will not affect only your facility, but also your projects. The standard compliance for at least 5 years means that you can reduce to a minimum the steps of the iteration of the projects and the reprogramming associated with them. Many intelligent features of the product assist engineers during installation and the specialists of the maintenance interventions on the system of protection against lightning and overvoltage. Equipped in this way, the series VPU offers a long-term solution and future-oriented protection against lightning and voltage surges. Take a look for yourselves.
The advantages of the surge Arrester, Weidmuller are:
The large window to the center of the module provides a clear vision of the status of the protective function.
The clip optimized for mounting on a support rail facilitates the assembly and removal of the modules, without the need for tools.
According to IEC 62305, the path from the module protection against surges to the PE connection may only be 50 cm. The fact you can rotate the base 180° means that you have a high degree of flexibility during installation, without impacting on overall visibility.
The contact of remote signaling with Push connection can be connected quickly and offers reliable information on the status of the protective function.
The engagement of the arrester in the base is clearly audible, which allows you to respond to the requirements of resistance to vibration imposed by the manufacturers of wind power plants.
