Whether in single-phase systems, in dc power supplies or at high system voltages there is always the right arrester for every kind of application. he multifunctional terminals provide the devices with an almost unlimited flexibility for connection with each other, but also with other DIN rail mounted devices in the same distribution board. Not only flexibility characterises the DEHNguard family. Moreover, it is the striking performance parameters setting trends all over the world. A high discharge capacity, low protection level and dual safety hermo Dynamic Control disconnector define the high reliability of the devices. Especially the DEHN-specific hermo Dynamic Control disconnector ensures the arresters to change to a safe isolated state even at extreme overloads. Apart from the surface temperature of the high-capacity varistor, also the intensity of the discharge current is evaluated. Apart from the standard visual indication with green and red coloured marks, the variants of DEHNguard... FM provide a 3-pole terminal for remote signalling.

DEHNguard : wo-part unit, consisting of base part and plug-in protection module DEHNguard FM: wo-part unit, consisting of base part and plug-in protection module; with remote signalling contact for control device (floating changeover contact) he pluggable DEHNguard surge arresters are real all-rounders. Whether in single-phase systems, in dc power supplies or at high system voltages there is always the right arrester for every kind of application. he multifunctional terminals provide the devices with an almost unlimited flexibility for connection with each other, but also with other DIN rail mounted devices in the same distribution board. Not only flexibility characterises the DEHNguard family. Moreover, it is the striking performance parameters setting trends all over the world. A high discharge capacity, low voltage protection level and the dual safety hermo Dynamic Control disconnector define the high reliability of the devices. Especially the DEHN-specific hermo Dynamic Control disconnector ensures the arresters to change to a safe isolated state even at extreme overloads. In parallel to the surface temperature of the high-capacity varistor, the intensity of the discharge current is also evaluated. Apart from the standard visual indication with green and red coloured marks, the variants of DEHNguard... FM provide a 3-pole terminal for remote signalling. As the remote signalling contact works also as a floating changeover contact, the remote signal can be used as a break or make contact according to circuit concept. Should, nevertheless, the varistor unit be overloaded despite the high discharge capacity of the DEHNguard devices, its two-part structure allows an easy exchange of the protection module without tools. 66

Both the dual monitoring unit for each circuit with hermo Dynamic Control and the code of the plug-in protection modules preset by the manufacturer characterise the high reliability of the equipment. Damage caused by subsequent installation errors of the installer or the operator is unlikely. Apart from the surface temperature of the high-capacity varistor, the hermo Dynamic Control monitoring and disconnection device evaluates also the intensity of the discharge currents. hus it ensures the arrester not to change into a safe and isolated state at standard overloads only but to remain safe also if the device parameters are significantly exceeded. he fault-resistant Y-circuit with 3 high-capacity varistors avoids damage at the surge protection in case of isolation faults in the generator circuit of the photovoltaic generator. Apart from the standard visual indication with green and red coloured marks, type DEHNguard Y PV 1000 FM provides a 3-pole terminal for remote signalling. As the remote signalling contact works also as a floating changeover contact, the remote signal can be used as a break or make contact, according to the circuit concept. he surge arresters of the DEHNguard Y PV family provide multifunctional terminals for connection of conductors and busbars for easy wiring with other DIN rail mounted devices. 69
