1 Relays for use in hazardous locations Class I, Division 2 and ATEX

2 Explosion protection in North America azardous (classified) locations, as defined in the National Electric Code (NEC), are locations where fire or explosion hazards may exist due to the presence of flammable gases, vapors, flammable liquids, combustible dusts, ignitable fibers or flying matter. Article 500 of the NEC divides all hazardous (classified) locations into Classes, Divisions and Groups. Phoenix Contact s hazardouslocation relays have been tested and approved for: Class I, Division 2; Groups A, B, C, D; and Class I, Zone 2 Class I: Areas in which flammable gases or vapors are or may be present in the air in quantities sufficient to produce explosive or ignitable mixtures Division 2: Environments that are not normally hazardous Groups A, B, C, D: Gas mixtures have been grouped on the basis of their characteristics: Group A Atmospheres containing acetylene Group B Atmospheres containing acrolein, butadiene, ethylene oxide, propylene oxide, hydrogen and fuel and combustible process gases containing more than 30 percent hydrogen by volume Group C Atmospheres containing ethyl ether and ethylene Group D Atmospheres containing acetone, ammonia, benzene, butane, cyclopropane, ethanol, gasoline, hexane, methane, methanol, naphtha and propane Class I, Zone 2 Nonsparking Equipment has no normally arcing parts or thermal effects capable of ignition Sparking with protected contacts Arcing contacts are in nonincendive circuits, or are inside a hermetically sealed container or sealed device Explosion protection in Europe The countries that make up the European economic area adopt directives as their national laws. The ATEX directive is the law of every country in the European community, and part of that law states that all products for use in explosive atmospheres must meet the directive. This means that all manufacturers of mechanical and electrical equipment intended for use in potentially explosive atmospheres that wish to place these products on the market within the European Union need to comply with the ATEX directive. Phoenix Contact s ATEX relays are dual rated for Class I, Division 2 and for ATEX. ATEXapproved parts are classified into Device Groups and Categories. Our ATEX relays are approved for Device Group II and Category 3G, for use in Zone 2 (gases). II (Device Group II) Areas with an explosive atmosphere, like chemical industries, mills (combustible gases and dusts) 3 (Category 3) Equipment that is intended for use in areas where an explosive atmosphere is unlikely to occur in normal operation and where operators must ensure a normal level of protection G Gas, suitable for atmospheres containing gas Ex Explosionproof electrical equipment II (Device Group) Surface installations C (Gas Group) ydrogen POENIX CONTACT

3 azardous location relays The industry has imposed stringent requirements on the reliability and safety of switching components in potentially explosive areas. In order to protect against explosion, all equipment that could be exposed to the flammable or combustible atmospheres in hazardous (classified) locations must be of a type suitable for installation in these areas. The classes and groups for which equipment has been certified are shown in the individual certifications under the respective categories and are marked on the equipment itself. Phoenix Contact s hazardouslocation relays our slim PLC Relay series have the required approvals for process control equipment. Our Class I, Division 2 (CID2) relays are UL/cUL listed for use in the Americas. Also available are dualrated ATEX relays: rated for both CID2 and ATEX approvals. Therefore, these relays are certified through UL/DEMKO and comply with the ATEX directive required for the European market. POENIX CONTACT
