The DEHNvap DVA CSP 3P 100FM is a prewired Type 1 + Type 2 combined lightning current and surge arrester. It is based on spark-gap technology and is specifically optimized for protecting power supply systems in mobile radio base stations. A standout feature is its RADAX Flow technology, which provides exceptionally high follow-current limitation and extinguishing capability, ensuring no tripping of 32 A gG fuses up to short-circuit currents of 25 kArms. The modular design uses a pluggable protection module for easy, tool-free replacement. It features an integrated visual status indicator (green/ok, red/faulty) and a remote signaling contact for constant status monitoring
