Description

The compact BLITZDUCTOR XTU combined lightning current and surge arrester is designed for protecting information and automation equipment and systems and distinguishes itself through its unique actiVsense technology. The arrester does not have a specific nominal voltage and can thus be used for all voltages from 0 to 180 V with a superimposed signal voltage (± 5 V/50 MHz). The nominal current is limited to 100 mA which is completely sufficient for information technology systems.

Its innovative actiVsense technology allows the arrester to detect the signal voltage and to automatically adapt the voltage protection level to this voltage. This makes the arrester ideal for applications where changing or slowly fluctuating signal levels (≤ 400 Hz) are to be expected. In case of interference, BLITZDUCTOR XTU arresters always provide a minimal residual voltage for every signal voltage and therefore afford maximum protection for the devices and system circuits connected to them.

BLITZDUCTOR XTU is available in two versions. The four-pole version provides protection for two separate balanced interfaces, that is the arrester automatically detects the operating / signal voltage for every pair and optimally adapts the voltage protection level for every signal circuit. This allows to protect two different balanced interfaces by means of a single arrester, thus reducing installation time, saving costs and reducing the number of arresters to be used. If only one signal interface is to be protected, a two-pole version can be used for a balanced data interface (one pair). This version also allows to directly or indirectly connect cable shields to the equipotential bonding.

This DIN rail mounted arrester is ideally suited for use in information technology transmission systems such as telecommunication, bus or measuring and control systems.

The protection module and base part must be ordered separately!

Detail 1

Optimally adapted voltage protection level with integrated actiVsense technology ensures protection of terminal equipment.

Detail 2

The protection module of the pluggable arrester safely snaps into the base part, thus ensuring vibration and shock resistance.

Detail 3

To ensure high availability of the signal circuits, the integrated LifeCheck feature allows to quickly check whether arresters are pre-damaged.

Detail 4

DIN rail mounting by means of integrated earthing contact.
