Nexans Euromold 800SA Surge Arrester

Interface C (for up to 42 kV)

Nexans Euromold 800 Surge Arrester is designed to protect 12, 24, 36 and 42 kV class components, including transformers, equipment, cable and accessories from high voltage surges resulting from lightning or switching. It has been designed to be used with the 480TB, 484TB and 489TB separable tee connectors.

These surge arresters are available for the following voltage classes:-

  • 6/10 (12kV)
  • 6.35/11 (12kV)
  • 8.7/15 (17.5kV)
  • 12/20 (24kV)
  • 12.7/22 (24kV)
  • 18/30 (36kV)
  • 19/33 (36) kV
  • 20.8/36 (42) kV


Specification & Standards –
