DEHN + SOHNE BXT ML2 surge arrestor modules

Available in different voltage levels, the BXT ML2 surge arrestor modules provide optimal protection for measuring and control circuits, bus systems, alarm systems and telecommunication systems. No matter if cable shields are earthed directly or indirectly, BXT ML2 protective modules can be used for any application. If, for example, direct shield earthing is not possible, the two-pole module allows for indirect shield earthing which is capable of carrying lightning currents. Indirect shield earthing prevents undesired equalising currents due to having the gas discharge tube connected to earth potential.

A universal base part, which is standard for all BLITZDUCTOR arrester modules, optimises storage and allows for prewiring and commissioning. The design of the arrester allows for hot swapping at the touch of a button without interruption of signal. The protection module snaps into the base part and is prevented from becoming loose.

Since no electronic components are installed in the base section, only the actual protection modules have to be monitored and maintained. With maintenance testing of the arresters by means of the RFID LifeCheck system, the module does not have to be removed.

Each BLITZDUCTOR XT module has an integrated RFID. The LifeCheck arrestor testing system constantly monitors the status of the arrester, which can be read out via DEHNrecord LC via the contactless RFID technology. BLITZDUCTOR XT also has an extensive range of accessories such as elements for labelling, earthing modules for unused cores or an easy testing module for circuit testing without having to disconnect connected wires.
