BLITZDUCTOR XT with an earthing module (grey). The lines can be tested by means of the measuring module (grey with lines) without disconnecting the terminals.

Details

Completely installed BLITZDUCTOR XT. Two-part design with universal base part and application-specific protection module. Especially space-saving design, for DIN rail mounting.

Universal base part accommodates all application-specific protection modules thereby minimising storage requirements and easing prewiring and maintenance operations. The modules can be easily removed from the base part without signal interruption due to make-before-break switch contacts.

BLITZDUCTOR XT combined arresters are pluggable and universal multipole DIN rail mounted lightning current and surge arresters for protecting measuring and control circuits, bus systems and telecommunication systems. They are particularly suited for installations and systems which require a high level of availability. For effective protection of terminal equipment under lightning and overvoltage conditions, BLITZDUCTOR XT arresters combine the permanently high impulse current discharge capacity of a lightning current arrester with the low voltage protection level of a surge arrester.
LifeCheck allows quick and easy testing of arresters without removing the module. Integrated into the protection modules, LifeCheck permanently monitors the proper condition of the arrester and acts like an early warning system, detecting imminent electrical or thermal overload of the protection components. The status of the arrester can be read out within a matter of seconds via contactless RFID technology by means of the portable DEHNrecord LC reader. The LifeCheck feature also saves the date of the last test of the protection module and indicates it. Stationary installed, a condition monitoring system permanently monitors the condition of up to 10 BXT arresters.
The module locking system ensures safe operation. Thus the arrester provides protection against vibration effects and shock up to a 30-fold acceleration of gravity. The function-optimised design of the arrester ensures both fast and easy replacement of SPD modules which house all relevant protection elements.
A wide range of accessories makes BLITZDUCTOR XT arresters particularly user-friendly. Elements for labelling, earthing of unused lines or easy testing of lines complete the product range.

BXT ML4 B...:
LifeCheck-equipped protection modules for four single lines or two pairs for protection against high partial lightning currents and surge pulses.
BXT ML2 B....:
LifeCheck-equipped protection modules for two single lines or one pair for protection against high partial lightning currents and surge pulses. Type BXT ML2 ... S additionally provides the possibility of direct or indirect shield earthing.

The function-optimised design of the device allows both to safely plug the protection module into the base part and to remove it without problems. The module 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 spring contacts and the module release spring. A mechanical reverse polarity protection ensures that the module is installed in the correct position.

Up to four lines can be connected on two levels. For DIN rail mounting purposes, lines of a pair belonging to each other are connected on top of one
another.

If the line shield cannot be earthed on both sides for technical reasons, one-sided indirect shield earthing might be advisable. This can be performed by using protection modules of type BXT ML2 ... S. The terminal 3, 3´ is connected to a gas discharge tube which is capable of carrying lightning currents and prevents compensating currents. Transient impulse currents on the shield are discharged via indirect shield earthing.

In case of a stranded cable, unused lines should be laid and earthed. If the unused lines are connected to base parts, earthing modules of type BXT M4 E should be used. These reserve space for retrofitting a protection module and the lines can be integrated efficiently into the equipotential bonding.

The protected lines always
have to be assigned to terminals 1´ to 4´ (protected) of the base part. In order not to reduce the protective effect, protected and unprotected lines have to be installed separately.

The terminals in the base part can be used with many two-pole modules for direct or indirect shield earthing. In particular in bus systems, it is advisable to use the EMC spring terminal for large-area connection of line shields.

Space-saving surge arrester module with LifeCheck feature for protecting two pairs of stranded signal interfaces. If LifeCheck detects thermal or electrical overload, the arrester has to be replaced. This status is indicated contactlessly by the DEHNrecord LC / MCM reader.

Presumably available in the second quarter 2012
