Ex d flameproof ATEX enclosures

Equipped Ex d flameproof ATEX enclosures mounted on a frame

Our Ex d flameproof ATEX enclosures contain the components that could ignite the atmosphere in a housing that withstands an internal explosion and prevents it from spreading outside. In aluminium alloy, cast iron or 316L stainless steel, they cover gas groups IIB, IIB+H2 and IIC, with IP66 protection, for ATEX zones 1, 2, 21 and 22. Not sure which type of protection you need? Read our guide Ex d or Ex e: how to choose.

Symbol: d. Type of protection in which the parts that could ignite an explosive atmosphere are placed in an enclosure that withstands the pressure of an internal explosion and prevents the explosion from spreading to the surrounding atmosphere.

Applications: distribution and control panels, motors, transformers, heaters, lighting.
