NPE lightning current arrester class I+II, based on isolating spark gap technology. Lightning current capable and rare-gas-filled summation current spark gap for the use between N - PE wire.
- NPE lightning current arrester
- No blow-out vents, thus, not requiring any safety clearance to other installations
- Discharge capacity up to 100 kA (10/350 µs)
- High insulation resistance
- EAC certification
