FCEN is a galvanised steel square locked conduit. This general purpose conduit is very flexible and has many applications in industrial applications, construction, underfloor wiring systems, industrial machines. Since FCEN is a conduit without a plastic cover, it is inherently fire retardant and is a good solution for tunnel, rail and underground applications, in situations where a high IP rating is not required. Type FCEN meets the requirements set for London Underground LUL 1-085 and EN45545.
