Ex-Control and distribution systems ATEX

If electrical apparatus is to be used in hazardous areas, i.e. potentially explosive atmospheres, where arcing or sparking can occur, it must be protected according to EN 60079 pp. by special constructional measures. CEAG explosion- protected products derives its high degree of safety through the combi­nation of various types of protection. Thus, flameproof encapsulated devices (Ex-d), for instance, are also integrated in enclosures of the „Increased Safety“ type (Ex-e). As these components are of modular design, they can be com­bined according to customers‘ requirements. The modules are inserted by simple snap-on rail mounting. Electrical apparatus with metal enclosures may be used in type „flameproof enclosure“ (E-d) without any volume limit. Up to three high- capacity apparatus with non-metal enclosures may take up an enclosure volume of up to 2000 cm3. However, the heat generated in the enclosure must be dissipated, so that the temperature on the external surface of the enclosure does not exceed the limit set by the respective temperature class.

Ex-Distributions in Moulded Plastic Design

CEAG products provides explosion protection in a snap – and that also applies to distributions. Electrical distributions for Ex-areas must be protected according to EN 60079 by constructional measures. Thus, the Eaton’s Crouse-Hinds Business flameproof moulded-plastic distributions provide type Ex-e protection.

Ex-Distributions in Metal Design

Distributions made of stainless steel or powder coated sheet steel for protection against aggressive environments are used for lighting, heating, motor and socket circuits in potentially explosive atmospheres. The distributions contain components with flameproof enclosures. These flameproof components, such as MCBs, fuses etc., provide thermal and magnetic protection and can be snapped on individually on the DIN rails.

Ex-d Enclosures and Distributions GHG 66

To use MCBs, fuses, contactors etc. which give off arcs in potentially hazardous areas, they must be integrated in Ex-d distributions. For just this purpose, Eaton’s Crouse-Hinds Business offers a distribution system comprising flameproof aluminium enclosures and Ex-e steel terminal boxes with a polyester powder coating suited for tropical and marine climates. Seven enclosure sizes can be combined into large distributions allowing integration of built-in components up to 630 A and 690 V.

Ex-d Distributions EJ-Series

Apparatus which gives off arcs or sparks can be integrated in distributions at low cost using flameproof enclosures. Built-in electrical components can be actuated by means of control units mounted from the outside on the covers. The extensive product line for use in explosion group IIB for the hazardous areas of Zones 1 and 2 fulfils the requirements of ATEX directive 2014/34/EU. Due to the most diverse demands, individualised distribution systems can be put together. Enclosures are connected via flameproof cable entries. The design and equipment of the distributions depends on customers‘ requirements.
