Protection of LED luminaires

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.
