IDIL Automatic Disconnection Device (ADD)


Idil primarily guarantees lighting continuity for a row of lamps should one be affected by a temporary earthing fault.

It is covered in guide UTE NF C17-210 intended for street lighting.

Automatic reset helps maintain lighting continuity in the event of a temporary fault.

The Idil-T2 version helps generate energy savings on illuminations during night-time off-peak periods by automatically stopping and restarting the illuminations at fixed times.


  • Lighting continuity by isolating the faulty lamppost without turning off the entire row.
  • Limited maintenance costs in the event of temporary faults thanks to the automatic reset function.
  • Energy savings: illuminations switched off at off-peak hours (version T2).
