The BLITZDUCTOR XTU is the first arrester to adapt itself to the nominal voltage of the installation, and is an innovation from DEHN + SÖHNE.
BLITZDUCTOR XTU arresters are combined lightning current and surge arresters for protecting information and automation systems. The Blitzductor XTU is a new, revolutionary technology: The nominal voltage is not specified; rather, the arrester can be used for all voltages in the range of 0 to 180V d.c. Innovative and pioneering technology allows the arrester to automatically detect the signal voltage of the information signal and adapt itself to this voltage.
It also continuously adapts its voltage protection level to the currently applied signal voltage and is thus ideally suited for all a.c. applications. In case of interference, the BLITZDUCTOR XTU arresters always have an adapted, minimal residual voltage for every signal voltage and provide maximum protection for devices and systems connected to them.
The new BLITZDUCTOR XTU arresters also considerably reduce planning efforts and minimise storage requirements. Even if it is not known during the design and planning stage which voltages are to be used for signal transmission on the various systems in a project, the BLITZDUCTOR XTU arrester now allows specifying a protective device early in the piece, as you know that the XTU will suit anything from 0-180V. This also simplifies procurement and storage.
Importantly, BLITZDUCTOR XTU arresters are also ideally suited for retrofitting existing systems with surge protective devices or replacing existing arresters. Because it is not always entirely clear or easily ascertainable which nominal signal voltages are being used, it can be difficult to select a voltage specific protection device. This is not an issue if BLITZDUCTOR XTU arresters are used, as it will self-programme to the correct settings.
BLITZDUCTOR XTU arresters are pluggable arresters consisting of a BXTU protection module, which contains all surge protection components, and a DIN rail mountable BXT base part. The base part features terminals for 2 twin wires and earth connection. An uninterrupted switch contact, or 'make before break' connection, allows the protection modules to be removed and inserted without interrupting system operation.
BLITZDUCTOR XTU 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 you to detect arresters pre-damaged by overload thus ensuring safe operation. There are also real-time condition -monitoring systems units available that can read the state of the XTU unit(s), and transmit this information to a desired location in real time.
DEHN + SÖHNE offers innovative lightning and surge protection products, customised protection concepts as well as engineering and test services in the company's in-house impulse current laboratory - all available though its local distributor Extreme Safety.
