Details
With a rated voltage of 1000 V, the compact and powerful single-pole DEHNguard 1000 (FM) surge arresters can be used for a wide range of applications.
The DEHNguard family is not only characterised by its high degree of flexibility, but also by its distinctive performance parameters which set standards worldwide: The high discharge capacity, low voltage protection level and dual "Thermo Dynamic Control" monitoring and disconnection device ensure maximum reliability.
The DEHN-specific "Thermo Dynamic Control" disconnector ensures that the arresters change into a safe, isolated state even in case of extreme overload. For this purpose, the surface temperature of the heavy-duty varistor and the intensity of the discharge current are used for evaluation.
The external design of the device reflects its field of application. DEHNguard 1000 (FM), with a width of two modules, entirely fulfils all mechanical requirements resulting from the high system voltages.
Apart from the standard visual indication with green and red indicator flags, DEHNguard ... FM arresters feature a three-pole remote signalling terminal. With its floating changeover contact, the remote signal can be used as a break or make contact according to the particular circuit concept.
