Dehn + Sohne Blitzductor XTU arresters

Dehn + Sohne’s Blitzductor XTU arresters are combined lightning current and surge arresters for protecting information and automation systems. The nominal voltage is not specified, but the arrester can be used for all voltages in the range of 0-180 VDC.

Blitzductor XTU’s actiVsense technology allows the arrester to automatically detect the signal voltage of the information signal and adapt its protection behaviour to this voltage. Moreover, it continuously adapts its voltage protection level to the currently applied signal voltage and is thus suitable for all applications where changing voltages occur. In case of interference, Blitzductor XTU arresters always have an adapted, minimal residual voltage for every signal voltage.

The arresters also feature a patented LifeCheck monitoring function which allows for easy testing of arresters during operation provided that the protection module is plugged in. This monitoring function also allows detecting if the arrester is pre-damaged by overload thus ensuring safe operation.
