DEHN’s universal BLITZDUCTORconnect combined lightning current and surge arrestors protect measuring and control circuits as well as bus and telecommunication systems. The built-in indicator and optional remote signalling unit report the status of the arrestors in real time.
To provide industrial measuring and control systems, and IT interfaces, with the necessary safety for operation, a protection concept withstanding all loads caused by lightning currents and surges is required. This range of products offers a high lightning current discharge capacity and a low protection level, which make the units ideal components for reliable terminal device protection.
They are available in a compact or modular design and both variants have a width of only 6 mm. Functions such as the new “secR” release buttons and push-in technology help with easy installation without the need for tools. The status indicator and a compatible remote signalling unit immediately report any failure in case of overload.
When servicing the modular arrestors, only the module is replaced. The signal is still available via the base section. The protective function for the system can be quickly restored by simply plugging in a new module without rewiring. To remove plug-in modules without accidentally pulling an adjacent module, they are equipped with release buttons which enable precise and safe replacement.
The modular arrestors have a disconnection function. Turning the module 180° and plugging it into the base part again interrupts the signal circuit for maintenance work. Measurements can thus be carried out quickly and without additional effort.
The arrestors of this range of products are equipped with an integrated visual status indicator. This clearly indicates the status of the arrester (green/red). In the event of an arrester overload, the indicator turns red. It is also possible to monitor arrester groups with a stationary remote signalling unit. The status of an arrester group is reported to a higher-level control system via a potential-free break contact.
