  • Application-optimised and prewired spark-gap-based type 1 + type 2 combined lightning current and surge arrester
  • Compact design due to space-saving spark gap technology with a width of only one module / pole
  • Fulfils the minimum requirements on the lightning current discharge capacity according to IEC 60364-5-53
  • Allows compact lightning equipotential bonding including protection of terminal equipment
  • Discharge capacity up to 50 kA (10/350 µs)
  • Operating state / fault indication by green / red indicator flag in the inspection window

Details

Series connection by means of a lightning-current-tested STAK 25 pin-shaped terminal
The space-saving and application-optimised DEHNshield family offers various benefits provided by type 1 + type 2 spark-gap-based arresters such as the "wave breaker function" (WBF). This function and the associated reduction of the pulse time mitigate the energy of the lightning impulse current to an acceptable level for downstream protection stages or terminal equipment. Moreover, DEHNshield arresters are directly energy coordinated with other arresters of the Red/Line product family.
Application-optimised DEHNshield combined lightning current and surge arresters combine lightning equipotential bonding up to lightning impulse currents of 50 kA (10/350 µs) and surge protection in a single device.
This clearly distinguishes DEHNshield from varistor-based arresters of this application and performance class.

Due to their technical parameters and the very compact design as spark-gap-based arrester with only one module / pole, DEHNshield arresters are ideally suited for this application class. For this reason, they are a space-saving and application-optimised solution in particular for residential buildings.
DEHNshield arresters also provide optimal protection in existing buildings without external lightning protection system where roof superstructures or overhead line supplies are installed which require type 1 SPDs according to VdS 2031.
No additional backup fuse is required if an installation is protected by backup fuses up to 160 A.
The energy-coordinated arresters even allow to protect terminal equipment if the distance between DEHNshield and the loads is ≤ 10 m. The spark gap without venting means and the small space requirements of the application-optimised combined lightning current and surge arresters enable easy integration into distribution boards.
The follow-current-limiting spark gap technology ensures selectivity with regard to low-current-rated fuses (35 A gG). This means that upstream fuses will not trip due to mains follow currents.

Busbars and pin-shaped terminals from DEHN + SÖHNE can be used for connecting DEHNshield to other DIN rail mounted devices. The type designation of DEHNshield allows to easily choose the right arrester for the relevant system configuration of the low-voltage consumer’s installation.
The operating state / fault indicator of every protective path needs no power to operate and instantly shows the operating state of the arrester. Apart from the standard visual indicator with green and red indicator flags, the DEHNshield ... FM versions 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.

Due to their parameters and design, the DEHNshield devices can be even installed upstream of meter panels in low-voltage consumer's installations.
