i-4Enclosed ControlGeneral InformationFebruary 1999Enclosure TypesEnclosures provide mechanical andelectrical protection for operator andequipment. Brief descriptions of thevarious types of enclosures offeredby Cutler-Hammer are given below.See NEMA Standards PublicationNo. 250 for more comprehensivedescriptions, definitions and/or testcriteria.NEMA 1NEMA Type 1 (Conforms to IP40) —for Indoor UseSuitable for most applications whereunusual service conditions do notexist and where a measure of protectionfrom accidental contact withenclosed equipment is required.Designed to meet tests for rod entryand rust resistance. Enclosure issheet steel, treated to resist corrosion.Depending on the size, knockoutsare provided on the top, bottomand sometimes on the side.NEMA 3RNEMA Type 3R (Conforms to IP52) —for Outdoor UsePrimarily intended for applicationswhere falling rain, sleet or externalice formations are present. Gasketedcover. Designed to meet tests forrain, rod entry, external icing andrust resistance. Enclosure is sheetsteel, treated to resist corrosion.Depending on the size, a blank coverplate is attached to the top (for aconduit hub) and knockouts are providedon the bottom.Cover-mounted pilot device holesare provided and covered with holeplugs.NEMA Type 4 (Conforms to IP65) —for Indoor or Outdoor UseProvide measure of protection fromsplashing water, hose-directed waterand wind blown dust or rain. Constructedof sheet steel with gasketedcover.Designed to meet tests for hosedown,external icing and corrosionprotection. Enclosure has two watertighthubs (power) installed top andbottom of one control hub installedin bottom — depending on size.Cover-mounted pilot device holesare provided and covered with holeplugs.NEMA 4XNEMA Type 4X (Conforms to IP65) —for Indoor or Outdoor UseProvide measure of protection fromsplashing water, hose-directedwater, wind blown dust, rain andcorrosion. Constructed of stainlesssteel with gasketed cover. Designedto meet same tests as Type 4 exceptenclosure must pass a 200-hour saltspray corrosion resistance test.NEMA 7 & 9 BoltedNEMA Type 7 — for HazardousGas LocationsFor use in Class I, Group C or Dindoor locations as defined in theNational Electrical Code. NEMA Type7 enclosures must withstand thepressure generated by explosion ofinternally trapped gases and be ableto contain the explosion so thatgases in the surrounding atmosphereare not ignited. Undernormal operation, the surface temperatureof the enclosure must bebelow the point where it could igniteexplosive gases present in the surroundingatmosphere. Designed tomeet explosion, temperature andhydrostatic design tests.PG.3.02.T.E
