Surge arrester

Protection against overvoltages :

  • Surge arresters are used increasingly frequently in street lighting for the safety of LED lighting fixtures, to protect them against transient overvoltages between phase and neutral or earth.
  • Device positioned as close as possible to the lamppost’s earth terminal for optimal protection (0.5m in accordance with standard NF C17-200).
  • For a long-term protection against transient & permanent overvoltages, LACROIX Sogexi offers a complete range of junction boxes.


  • Enables to maintenance staffs to check if the surge protector is at its end of life without public lighting network switched-on, so visible by day.
  • Our surge protector is a type «Y» with 2 varistors(1 on phase and 1 on neutral), which enables to work correctly even in case of inversion phase/neutral.
