Restricted breathing

Multipurpose distribution, switching and control units in "restricted breathing nR" protection



The multipurpose control boxes (categories 3 G and 3 D) are designed for Zone 2 areas at risk of gas explosions to EN 60079-15  and for Zone 22 to EN 50281-1-1. Restricted breathing enclosures are designed to limit the penetration of gas.
The enclosures can be made of stove-enameled sheet steel, stainless sheet steel, or polyester. In addition to standard enclosures, special enclosures are fabricated to customer specifications. The polyester enclosures can be combined like building blocks using plug-in flange joints. The same openings also accept flanges fitted with cable glands. Shielded cables are installed together with brass flanges holding suitable cable glands for integration into an equipotential bonding system.
