1.1OverviewEnclosed Control Products1Technical Reference11Enclosures provide mechanical and electrical protection for operator and equipment. Briefdescriptions of the various types of enclosures offered by Eaton are given below. See NEMA Standards Publication No. 250 for more comprehensive descriptions, definitions and/or test criteria.All Eaton enclosures are NEMA ICS 6 compliant.1Enclosure Type OverviewEnclosure Types11111111111Type 1 (Conforms to IP40)—for Indoor UseType 3R (Conforms to IP52)—for Outdoor UseType 4 (Conforms to IP65)—for Indoor or Outdoor UseType 4X (Conforms to IP65)—for Indoor or Outdoor UseSuitable for most applications whereunusual service conditions do not exist andwhere a measure of protection fromaccidental contact with enclosedequipment is required. Designed to meettests for rod entry and rust resistance.Enclosure is sheet steel, treated to resistcorrosion. Depending on the size, knockoutsare provided on the top, bottom andsometimes on the side.Primarily intended for applications wherefalling rain, sleet or external ice formationsare present. Gasketed cover. Designed tomeet tests for rain, rod entry, external icingand rust resistance. Enclosure is sheetsteel, treated to resist corrosion.Depending on the size, a blank cover plateis attached to the top (for a conduit hub)and knockouts are provided on the bottom.Provides a measure of protection fromsplashing water, hose-directed water andwind blown dust or rain. Constructed ofsheet steel with gasketed cover.Provides a measure of protection fromsplashing water, hose-directed water, windblown dust, rain and corrosion. Constructedof stainless steel with gasketed cover.Designed to meet same tests as Type 4except enclosure must pass a 200-hour saltspray corrosion resistance test.Cover-mounted pilot device holes areprovided and covered with hole plugs.1Designed to meet tests for hose-down,external icing and corrosion protection.When conduit connections are specified,enclosure has two watertight hubs (power)installed top and bottom or one control hubinstalled in bottom—depending on size.Cover-mounted pilot device holes areprovided and covered with hole plugs.11111111Type 7/9—for Hazardous Gas LocationsType 12 (Conforms to IP62)—for Indoor Use1For use in Class I, Group B, C or D; Class II,Groups E, F and Class III indoor locations asdefined in the National Electrical Code .Type 7/9 enclosures must withstand thepressure generated by the explosion ofinternally trapped gases and be able tocontain the explosion so that gases in thesurrounding atmosphere are not ignited.Under normal operation, the surfacetemperature of the enclosure must bebelow the point where it could igniteexplosive gases present in the surroundingatmosphere. Designed to meet explosion,temperature and hydrostatic design tests.Provides a degree of protection fromdripping liquids (non-corrosive), falling dirtand dust. Designed to meet tests for drip,dust and rust resistance. Constructed ofsheet steel. Hole plugs cover pilot deviceholes. There are no knockouts, hub coverplates or hubs installed.11111V10-T1-4Safety InterlockThe Type 12 enclosure can be ordered witha safety interlock on the door that can bepadlocked off. A vault-type door latchsystem is used. A tapered plate holds thegasketed door tight against the case edgeto provide a positive seal. The special doorinterlock consists of the door handle and ascrewdriver operated cover defeater.The cover defeater and the disconnectinterlock defeater are both recessedscrewdriver operated devices that cannotbe manipulated with other types of tools.Volume 10—Enclosed Control CA08100012E—November 2012 www.eaton.com304-grade stainless steel provided asstandard. Select 316-grade option forimproved corrosion resistance.
