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 discharge arrester with rare-gas-filled spark gap and very low protection level < 1.5 kV for the use in single-phase TT and TN systems.
  • Combined Arresters Type 1+2 (Class I+II)
  • Applicable at the boundaries LPZ 0A - 2
  • Test standard: IEC 61643-11 / EN 61643-11
  • 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
  • Vibration test standard: DIN EN 60068-2-6, IEC 60068-2-6
  • Shock test standard: DIN EN 60068-2-27, IEC 60068-2-27
  • Optical status indication (red pin appears)
  • Single modules can be replaced easily
  • Remote changeover contact (FM)
  • EAC certification
