Dehn + Sohne BLITZDUCTOR XTU universal voltage lightning and surge arresters

BLITZDUCTOR XTU arresters are combined lightning and surge arresters for protecting information technology and automation systems. They are different to other arrestors because the nominal voltage is not specified, but instead can be used for all voltages from 0 to 180 VDC. Each BLITZDUCTOR XTU uses technology which allows the arrester to automatically detect the signal voltage and adapt its voltage protection level to the currently applied signal voltage, making them suitable for many applications.

In case of lightning or transient surges, BLITZDUCTOR XTU arrestors always provide a minimal residual protection voltage for every signal input voltage and therefore afford maximum protection for systems and connected devices.

BLITZDUCTOR XTU arresters are also suitable for retrofitting existing systems with surge protective devices, or replacing existing arresters where it is uncertain which nominal voltage is to be used.

No programming or set-up is required. Each BLITZDUCTOR XTU consists of a BXTU protection module, containing all the surge protection components, and a DIN rail-mountable BXT base. The base features terminals for two twisted pairs of wires and an earth connection. A switch contact allows the protection modules to be removed and inserted without interrupting system operation.

BLITZDUCTOR XTU arresters feature the LifeCheck monitoring function, which allows for easy testing of arresters during operation. This monitoring function detects any arrester that is damaged, allowing for easy replacement and full protection of devices and systems.
