DEHNvenCI 1 255: Single-pole combined lightning current and surge arrester with integrated backup fuse
DEHNvenCI 1 255 FM: With remote signalling contact for monitoring device (floating changeover contact)

Details

Featuring the functional Red/Line family design, coordinated DEHNvenCI combined lightning current and surge arresters provide maximum system protection and take up little space. The features of the practice-proven DEHNventil family were combined with a lightning current carrying arrester backup fuse in an enclosure with a width of only two modules.

With switchgear installations getting more and more compact, it is difficult to install lightning current arresters in conformity with the standard. DEHNvenCI arresters allow space-saving integration of a combined lightning current and surge arrester and are said to meet the protection requirements of modern switchgear installations. The integrated arrester backup fuse is dimensioned to ensure maximum discharge capacity and optimal system protection.
The need to select and install an arrester backup fuse is eliminated, ensuring short connecting cable lengths as required in IEC 60364-5-53.
Consequently, DEHNvenCI is an efficient combined arrester which is easy to install.

The energy-coordinated arresters even allow protection of terminal devices or sensitive electronic systems in modern switchgear installations if the distance between DEHNvenCI and the loads is ≤ 10 m.

The patented RADAX Flow technology for follow current limitation and extinction allows high availability of the electrical consumer's installation to be protected.

Even in case of short-circuit currents as high as 100 kArms, DEHNvenCI can be used in industrial systems without restrictions.

The ability to carry lightning impulse currents without destruction and simultaneously reduce the energy to an acceptable level for terminal devices ensures the availability of the switchgear installation in case of a lightning strike. This considerably reduces the risk of high-loss failures.

The operating state / fault indicator of DEHNvenCI, which houses the fuse monitoring system and needs no power to operate, shows the operating state of the arrester. Apart from the standard visual indicator with green and red indicator flags, DEHNvenCI 1 255 FM devices 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.
