Railways Safeboxes


The SafeBox is the new electrically insulated class II industry standard power range of products for safeguarding signalling distribution on the rail and road networks.

The SafeBoxes are manufactured with a full EIC (Electrical Insulated Coating) encapsulating a stainless steel substrate material to overcome a range of challenges encountered during the installation, maintenance and protection of power distribution equipment.
