Red/Line – Surge protection for power supply systems
DEHNcord type 2 – surge arrester
The flexible and space-saving DEHNcord (two-pole, single-pole) can be installed in installation systems such as the terminal compartments of end loads, cable ducts or flush-mounted systems.
When using the DEHNrecord SD, measurements and analyses of all relevant parameters are conducted on one single device. More performance, less effort.
Limited space often makes installation difficult. DEHNcord 3P compact type 2 and type 3 surge arrester meets all relevant standards and offers reliable protection.
Robust and powerful. Protect employees, limit overvoltages, prevent AC corrosion: The decoupler provides protection against transient, temporary and long-duration overvoltages.
Protects PV systems from lightning and surge damage. It’s suitable for earthed (earthing of DC+ or DC-) and floating systems and can be used up to 10 kA without additional backup fuse.
DEHNguard ME DC Y 950 FM
Protects direct current applications up to 950 V. With DCD technology - in the event of an overload, the DC disconnector safely disconnects the protective device.
The switch-spark gap combination in type 2 arrester DEHNguard ACI makes upstream fuses superfluous. As a backup fuse is no longer required, you save time, space and material.
Up to 400/690 V: DEHNguard SE CI 440
For industrial applications with a rated voltage of 400/690 V. Overvoltage protection and backup fuse combined in a single device. This saves space in the switchgear cabinet. Available in 2 versions: Industry and wind turbines.
DEHNguard M YPV
Type 2 arrester for the DC side. Protects PV system components like inverters and PV modules against overvoltage. Available in 2 versions: ≤ 1170 V and ≤ 1500 V.
DEHNcord 3P with disconnection function
Small and compact arrester - with full performance! Ideally suited for LED mast lights and wherever an optimal protection solution for restricted space conditions is required.
DEHNshield with remote signalling contact
The proven space-saving combined arrester DEHNshield is now also available with a floating remote signalling contact. This allows an easy integration and monitoring through your factory master control system.
