Combined modular multi-pole arrester for lightning (LEMP) and transient (switching-) surge voltage protection (SEMP) of low-voltage electrical distribution systems for industrial, commercial and private use. Suitable for the installation at the 0A-2 boundaries according to the Lightning Protection Zone Concept of IEC 61312.
- ready for use, modular all-in-one protection unit
- hermetically sealed, built-in rare-gas-filled isolated spark gaps
- no blow-out vents, i.e. not requiring any safety distances for installation
- up to 100 kA discharge capacity (10/350 µs)
- high quenching capacity of follow-on short circuit currents
- high insulation resistance Riso > 10 GΩ
- protection level from < 0.75 kV up to 1.0 kV
- V-wiring over multi-functional terminals possible
- no leakage-currents, i.e. allowing installation upstream of power meters
- ptional remote contact (FM)
