ILME: APX Gehäuse aus Aluminiumdruckguss - APV ATEX

1 APX ATEX containing boxes ILME has a long history of manufacturing die-cast aluminium alloy containing boxes to meet the protection requirements of industrial environments. AP series containing boxes are now available in a new version called APX . APX containing boxes are Ex components and therefore suitable for fixed installations in explosive atmospheres due to the presence of gases and/or dust , classified as Zone 2 (gases) and/or Zone 22 (dust) in ATEX Directive 94/9/EC. The range covers the 7 sizes that are now available in the ATEX version (APX) painted in RAL 7040 grey (like APV standard models). The gasket, in EPDM for sizes 9, 11, 12, 14 and 19 and in silicon rubber foam for sizes 20 and 21, is fitted in the perimetral slot on the cover and is specifically designed to guarantee the IP66/IP67 degree of protection required for Ex protection types, even in presence of the maximum temperatures applicable to the marking. APX boxes are supplied with an external earth terminal complete with an M4 self-forming stainless steel screw, a flat washer and a crimp ring lug in tinned copper for protection leads with a cross-sectional area up to 6 mm 2 in order to guarantee the external equipotential bonding indicated in ATEX standards. All boxes are also supplied with an instruction sheet containing installation, operation and maintenance information and with an EC certificate of conformity. The inside of the boxes contains supports for grounding and for the application of the bottom plates. All boxes have closed walls. The instruction sheet supplied with each product shows the points that can be drilled on each side (the cover must never be drilled). The IP protection degree marked on the product is guaranteed only if each opening is coupled with an entry device with an equivalent or higher IP protection degree, which must be chosen in compliance with the requirements of the ATEX Directive and which must have a classification suitable for at least zones 2 and 22. Classification In accordance with ATEX Directive 94/9/EC, APX boxes conform with the following standards: EN 60079-0:2009 (that replaces the previous standards concerning dust, EN 61241-0:2006 and EN 61241-1:2004, and the previous edition of standard EN 60079-0:2006 only for the general requirements on gases), EN 60079-15:2005 (gases, protection type “n”), and EN 60079-31:2009 (combustive dust, protection type with “t” enclosures). Boxes are also compliant with the Low Voltage Directive 2006/95/EC because they have been manufactured in accordance with EN 60670-1:2005 product standards (classification CEI 23-48), EN 60670-22:2006 (classification CEI 23-94). Classification: Group II components– Category 3 GD Identification marking used for protection types: Ex II 3 GD Ex nA IIC T6 Gc U Ex tc IIIC -20 °C ≤ Ta ≤ 85 °C Dc IP66/IP67 U Protection degree in accordance with EN 60529: IP66/IP67 Max permitted surface temperature (dust): 85 °C Temperature class (Group II equipment, gases): T6 Electrical properties: Guaranteed electrical continuity Fields of application Fixed installation in areas exposed to a potential risk of explosion, classified as Zone 2 (gases) and/or Zone 22 (dust). NOTE The classification of areas should respectively comply with the following standards: - Standard EN 60079-10-1:2009 (that has replaced EN 60079-10) for gases - Standard EN 60079-10-2:2009 (that has replaced EN 61241-10) for dust Italian guides CEI 31-35 (gases) and CEI 31-56 (dust) are currently being updated. The boxes have a very high resistance to weathering agents and are suitable to be installed outdoors.
