EX rated enclosures and junction boxes for hazardous areas

CEE Norm can meet the needs of enclosures for hazardous areas with Hensel’s EX certified range of cable junction boxes, terminal boxes and empty boxes. The DK series enclosures are suitable for use in Zone 2 and Zone 22 hazardous areas as defined by ATEX where the presence of dust or gas creates the potential for explosion and where any sources of ignition must be eliminated.

Manufactured from impact resistant, surface-coated polycarbonate, and offer IP65 sealing. EX certified in accordance with standard 94/9/EG, the enclosures are also flame resistant and self-extinguishing to 960 degrees C as defined in the EN 695-2-11 glow wire test. Where there is a fire, the enclosures are halogen-free and silicone-free, ensure no toxic fumes will be produced.

The cable entry boxes provide can accept cable sizes from 1.5mm up to 25mm. The terminal boxes are fitted with terminal blocks for copper conductors in sizes from 1.5mm up to 35mm. The empty boxes are available in a range of sizes and supplied as ‘component’ products for OEM applications to provide protection for systems to be used in hazardous areas. For all of the enclosures cable entry is via metric knockouts and cable glands that maintain IP65 sealing.

Typical applications for the DK series EX rated enclosures include the chemical plants, agricultural operations, corn mills, refineries, sewage treatment plants, cement factories, enamelling plants, and wood-processing plants.
