DEHNcord R 3P …: Compact three-pole version; for use with electric sun shading systems
DEHNcord 3P ...: Compact three-phase version; for use in confined spaces, e.g. in a wall box
Another important field of application is the protection of outdoor LED lights. The DEHNcord L … SO LTG version is particularly suitable of this purpose and can be integrated in the junction box of an LED light pole. This version additionally allows a control phase to be protected and the load circuit to be interrupted if the DEHNcord arrester is faulty. This makes it considerably easier to detect faults, thus facilitating testing and maintenance of the system. Despite the powerful protective circuit, the compact enclosure also houses a disconnector and a visual operating state / fault indicator. DEHNcord is a type 2 surge arrester and can therefore be installed according to the lightning protection zones concept at the transition from 0B – 1 and higher. This ensures installation of surge protective devices in line with the standard wherever space is restricted.
The IP type can both be integrated in junction boxes and directly in the pole (cables can be entered into any junction box thanks to IP 65 degree of protection).
LED lights are optimally protected against surges by the DEHNcord series. The LTG version is ideally suited for integration in fuse boxes. Thanks to its adapted design, the device fits perfectly into the upper area of the EK480 junction box from Langmatz.
If no junction box is installed in the LED light, the EK480 fuse box with integrated DEHNcord surge protective device can be used as a complete solution. The innovative plug-in technology allows the wires to be connected to the luminaire without tools, and the system can be installed more quickly. Should it become necessary, the surge protective device can be easily replaced at any time.
The multipole DEHNcord R 3P adapter is a type 2 surge arrester. It protects sun shading systems and Venetian blinds and is installed in the connecting cables of the drive. In addition, this version can also be used to protect buildings against surges induced on the building facade. DEHNcord R 3P meets the requirements of the lightning protection zone concept as well as the installation standard for buildings IEC 60364-4-44/-5-53.
