DEHN + SOHNE DEHNvenCI combined lightning current and surge arrester

The DEHNvenCI combined lightning current and surge arrester with integrated backup fuse combines maximum system protection and compact dimensions in a single device.

The DEHNvenCI is a combined lightning current and surge arrester with a discharge capacity up to 25 kA (10/350 µs) and combines system protection and compact dimensions in a single device. Each arrester including integrated backup fuse only takes up two standard DIN modules.

The need to select and install arrester backup fuses is eliminated, ensuring short connecting cable lengths as required in AS/NZS 3000 and IEC 60364-5-53. DEHNvenCI is an efficient combined lightning current and surge arrester that is easy to install.

Energy coordinated with downstream terminal equipment is guaranteed using the DEHNvenCI with distances ≤5 m between the primary protection and the terminal device. The ability to carry lightning impulse currents without destruction and simultaneously reduce the energy to an acceptable level for terminal equipment ensures the availability of installation in case of a direct lightning strike.

The patented RADAX Flow technology ensures 50 Hz follow current limitation and extinction and thus high system availability, even in the case of short-circuit currents as high as 50 kA_RMS.

The operating status indicator on DEHNvenCI provides information about the integrity of the arrester even if no operating current is present. Apart from the standard visual indication with green and red indicator flags, the arrester features a potential free remote signalling contact.
