Surge protection for 5G cell site (mobile base station)
Protecting the power supply
Avoid false tripping of systems fuses
The infrastructure in main and system power supplies is protected by proven combined lightning current and surge arresters.
DEHN combined arresters are characterized by a particularly high follow current extinguishing capability and follow current limiting capacity. This avoids false tripping of system fuses that would lead to the disconnection of mobile radio systems. For you, this means particularly high system availability.
Product recommendation
Universally applicable – independent of the feeding grid system
DEHNvap protects the 230/400 V power supply of cell sites.
This combined arrester is universally applicable, independently of the supplying grid system:
All DEHNvap versions reliably protect TT and TN-S systems (3+1 configuration).
DEHNvap NG
Specially developed for mobile communication systems and “ready for 5G”. The pluggable combined arrester for three-phase TT and TNS systems protects the power supply in just 4 modules.
- Prewired type 1 + type 2 spark-gap-based combined arrester, optimized for protecting mobile radio systems
- Maximum system availability thanks to Rapid Arc Control / RADAX Flow follow current limitation
- Discharge capacity up to 100 kA (10/350 µs)
- No tripping of 32 A gG fuses up to short-circuit currents of 25 kArms
- Protection of terminal devices within 10m
