BLITZDUCTOR XTU INFORMATION TECHNOLOGY SYSTEMS
®
Universal lightning current / PLUGGABLE SPDS FOR DIN RAIL MOUNTING
surge arrester

• With actiVsense technology
– Automatically detects the operating voltage of
the wanted signal from 0 to 180 V
– Optimally adjusts the voltage protection level to
the operating voltage currently applied
– Low voltage protection level, also suited for the
protection of terminal equipment
• Eases your processes

– Reduction of the variety of types
– Only one type of SPD for different signal lines
– Easy planning and storage
– Can be easily retrofitted

Example of use of BLITZDUCTOR XTU.

BLITZDUCTOR XTU combined lightning current and surge arresters for the Completely mounted BLITZDUCTOR XTU.
protection of information and automation systems stand out due to their Two-part design with base part and SPD
new, revolutionary technology: The nominal voltage is not specified thus module. Particularly space-saving, for DIN
the arrester can be used for any voltage in the range from 0 to 180 V d.c. rail mounting.
Its innovative technology allows the arrester to automatically detect the
signal voltage of the wanted signal and to adjust its protection perform-
ance to this voltage. Moreover, it continuously adjusts its voltage protec-
tion level to the operating voltage currently applied and is thus ideally
suited for all applications where changing voltages occur.

In case of interference, BLITZDUCTOR XTU arresters always have an
adjusted, minimal residual voltage for every signal voltage thus providing
maximum protection for the devices and systems connected to them.

BLITZDUCTOR XTU arresters also considerably reduce planning efforts
and minimise storage requirements. Even if it is not known at the plan-
ning stage which voltages are used for signal transmission, BLITZDUCTOR
XTU arresters now allow to specify a concrete protective device even at
the planning stage thus facilitating procurement and storage at the exe-
cution stage of the project.
BLITZDUCTOR XTU arresters are also ideally suited to be retrofitted into
existing systems or to replace existing arresters as it is frequently not
entirely clear which types of nominal voltage are to be used.This does not
matter if BLITZDUCTOR XTU arresters are used. click

The function-optimised design of the arrester allows both to safely plug
the arrester module into the base part and to remove it easily. The mod-
ule is secured in the base part by snapping it in (audible click). When
pressing the grey buttons, the module can be removed with little effort.
This is ensured by the laminated contacts in the base part and the release
spring of the module. A mechanical reverse voltage protection ensures
that the module is installed in the correct position.
