The DEHNcord type 2 surge arrester (two-pole, single-pole) can be installed in installation systems such as the terminal compartments of end loads, cable ducts or flush-mounted systems.
The device reliably protects, for example, outdoor LED lights from surges caused by lightning interference. The product can be installed wherever the performance of a standard type 3 surge protective device for terminal equipment reaches its limits. DEHNcord ensures surge protection is in line with the standard wherever space is restricted. According to the standard, DEHNcord is a type 2 surge arrester - it can also be used at the transition from Lightning Protection Zone LPZ 0 B to 1 or higher.
The device meets all normative requirements. It has a short-circuit current withstand capability Isccr of 25 kA rms in case of mains-side overcurrent protection and a total discharge current total of 20 kA (8/20 µs).
The device houses a mechanical operating state/fault indication and a tried and tested disconnector which does not disconnect the connected load as soon as it is tripped. If space is restricted in the cable duct, the installation benefits of DEHNcord resulting from its flexible terminals become evident. DEHNcord can be adapted to existing installation systems.
