Specifications:
The GUB series junction boxes are designed for hazardous areas classified as Zone 1, 2, 21, and 22, suitable for environments with explosion and fire risks or combustible dust. They are made from a specific aluminium alloy known for its mechanical properties and are available in eight sizes. The boxes are IP66 rated, ensuring protection against dust and water.

Design and Construction:
The junction boxes feature a screw-on lid with a safety fastening grub screw and are coated with polyester in RAL 7035 light grey. The body and lid are made from low copper content aluminium alloy. The gasket is resistant to acids, hydrocarbons, and high temperatures, placed between the body and lid. Stainless steel is used for bolts, screws, and earth screws, which are present both inside and outside the body with anti-rotation brackets. Mounting is facilitated by cast aluminium feet.

Applications:
