Solutions to your needs


Reliability and conformity of installations

Supply circuits for emergency lighting installed in tunnels must meet the following requirements:
  • EN 50362 European standard, French government Directive No. 2000-63 of 25 August 2000 on safety in tunnels and national road network, 
  • NF C 32-070 French standard, 
  • Guides CETU defining the fire behaviour of road tunnels.
To meet these requirements, MARECHAL® equipment is among the only one on the market to have been tested and certified by C.S.T.B France (Centre Scientifique et Technique du Bâtiment), and IMQ laboratory in Italy.

Suited materials for the users’ safety
In order to guarantee maximum safety, the materials used in the making of MARECHAL®’s boxes and connectors are corrosion resistant and shockproof (IK09). In the event of a fire, these materials do not produce any halogen gases or smoke. They are resistant to agrresive environemnts (humidity, corrosion, pollution) in industrial sectors and road infrastructures.


Optimised maintenance and washing
All boxes and connectors are watertight and withstand the use of high-pressure washing during tunnel maintenance.


Ease of intervention for emergency services
The boxes have been specially developed in collaboration with emergency services who specialize in tunnel rescue.
