EJBX enclosures are the AISI 316L stainless steel version of the EJB series and share its Ex db IIB+H2 certification. The shot-peened finish and the material make them suitable for offshore, marine and chemical installations where aluminium is not permitted. They are the basis for flameproof junction boxes, control stations and panels, including versions with viewing windows.

The type code gives the size (0 … 20A) and the version. The dimensions of the U.AI/U.AIU empty enclosures (versions with approvals for the Asia Pacific region) differ slightly in depth from the standard ones.
