Overvoltage Protection Devices
Thunderstorms cannot be prevented – but thunderstorm and consequential damage can

There are nearly a million lightning strikes each year – a risk best avoided. BETA surge arresters offer protection against overvoltage from the infeed to the socket. As a result, systems and plants, as well as expensive devices are protected and consequential economic damage aused by system, plant, and device failure is prevented. The entire new lightning, overvoltage and device protection concept includes uniform plug-in modules. In addition, decoupling inductors are no longer required, thus providing the easiest installation and configuration to date.
