Lightning current discharge arrester (class I) with rare-gas-filled spark gap for the use in three-phase TT and TN-S systems. They provide extremely high discharge capacity with at the same time very low protection levels and they also do not need any damageable internal or external electronic trigger.
- Lightning current arresters type 1 (class I)
- Applicable at the boundaries LPZ 0A - 1
- Test standard: IEC 61643-11 / EN 61643-11
- Vibration test standard: DIN EN 60068-2-6, IEC 60068-2-6
- Shock test standard: DIN EN 60068-2-27, IEC 60068-2-27
- Mounting on 35 mm DIN rail (EN 60715)
- Enclosure material: thermoplastic with the colours yellow and black
- No leakage currents, thus, allowing installation upstream of power meters
- Optical status indication (red pin appears)
- Single modules can be replaced easily
- Remote changeover contact (FM)
- EAC certification
