WALTHER CEEtyp plugs andsockets are according tointernational standards IEC/EN 60 309-1/08.97 and 60309-2/97.

These standards weredeveloped as a successor ofthe European Standard CEE17. European and nationalstandards were superseded

by international standards.

Industrial installation

According to DIN/VDE 0100 T550 for German industrialplants since 01.01.1981 theconnection of the electricalconsumer to the network isonly allowed with CEEtypplugs and sockets.

In most of the countriesworldwide CEEtyp plugs and

sockets are introduced inaddition to eventually otherexisting products. For specialapplications in industrialareas the following additio-nal standards, requirementsand practical informationcould be useful:

Construction sites

Manufacturer standardsfor assemblies for

construction sites

1.DIN/VDE 0612/05.74 wasvalid on itself until30.11.1991

2.IEC/EN 60439-4:1990(DIN/VDE 0660 T501/02.92),

is valid since 01.12.1991.For the changeover atransition period till30.11.1996 was fixed. Thefabrication of assemblies forconstruction sites does thusno longer comply to thestandard DIN/VDE 0612.

3. IEC/EN 60439-4/A1 (DIN/VDE 0660 T501/A1:1996-12),valid from 01.09.1996.Valid on itself from01.09.2001.Thus the IEC/EN 60439-4:1990 might still be appliedfor fabrication until31.08.2001 (see BG-regulations).

4. IEC/EN 60439-4/A2.This modification waspassed on 01.08.1999.For Germany a summarisedversion of the modificationcalled DIN/VDE 0660 part501:2000-05 was published.

This will be valid on itselffrom 01.08.2002.

The most important

modification in the IEC/EN

60439-4/A1 is ...

... the demand to protect allplugs and sockets

Electrical installation on

farms

Unfortunately there is nointernational standardespecially for farms. InGermany the specialstandard DIN/VDE0100T705/10.92 is dealing withelectrical installation onfarms. Electrical supplysystems with sockets in TN-,

TT-, IT-networks have to beprotected by a residual-current device with a ratedresidual operating current ofIn30 mA. This RCD has tobe operated at least once amonth and in addition afterthunderstorms. The IPdegree of the installationshould be at least IP 44, inareas with intensive dust IP54. We recommend ourCEEtyp plugs and socketsfor harsh environments onfarms and other areas withdust or other aggressive andcorrosive atmospheres.In Germany and other DIN/VDE related countries theDIN/VDE 0105 T 15 isapplicable for farms andfarming areas and requiresamong other items thefollowing:

4.5 Plugs and sockets4.5.1Plugs and sockets

according to IEC/EN 60 309,DIN/EN 60 309 shall beused.4.5.2Plugs and socketsshall be protected againsthumidity and damage. Keysand keyways on thesesystems shall not bedestroyed to allow misuse.Damaged plugs and socketsshall not be used.4.5.3Damaged or destroyedplugs and sockets shall bereplaced by a skilled

person1).4.5.5Plugs and couplersshall not be pulled off theircounterparts through theircables.

Note1):According to DIN/EN 50110-1/EN 50110-1 (1996/07/02) askilled person is a personwith relevant educationexperience to enable him orher to avoid dangers whichelectricity may create (IEV826/09/01 modified). In DIN/

VDE standard it isadditionally clarified thatsuch a skilled person shouldbe registered with theelectrical supply authority asa skilled person if dealingwith electrical installation onfarms.

Circuits with voltagesabove 50 V shall have anearthing contact. Theearthing contact, the phasesand a neutral, if any, arearranged on a circle. Theearthing contact has thelargest diameter.

The diameter of theearthing contact is

dimensioned in a way thatprevents contact with otherpins through the isolatingmaterial.

The earth contact makesfirst and breaks last. AllCEEtyp plugs and couplersalso have an extended earth

contact on the back of theinsert which prevents in anunlike event separation of theconductor loop from the earth

The earth position isdetermined by looking into asocket from the front with thekeyway at the bottom 6oclock. The voltage and thefrequency then determine thehour position of the earth.This prevents the possibility

of connecting items ofdifferent voltages orfrequencies in accordancewith IEC 60 309-1.

1)For frequencies over 60 Hzup to 50 Hz , the colour greenmay be used, if necessary, incombination with the colourfor the rated operatingvoltage.

2)In countries whereaccessories of series IIcurrent ratings are used, thecolour orange is reserved for125/250 V~ AC and thecolour grey is reserved for277 V~ AC accessories.

Materials

1) Terminals for pilot conduc-tors, if any, shall allow theconnection of conductorshaving the same nominalcross-section areas as theterminals of 16 A accesso-ries having rated operating

voltages exceeding 50 V.

2) Classification of conductors:According to HD 383 S2 2solid (class 1);stranded (class 2);flexible (class 5).

3) for connecting blocks,terminal size 2

4) For the time being there isno conformity with terminalsize 9 required.

The cross-sectional areas ofthe terminals are inaccordance with IEC/EN 60309-2/97 table 107. Thetemperature rise of a contactmay be + 50 C under thetest conditions beingdetermined in table 8.

Enclosures and contact

carriers

are serially made of high-quality self-extinguishingplastic material which isfree from cadmium, PVCand halogene. Suitable forambient temperatures of- 25 C up to + 100 Cunder load.

Contacts

are made of brass.For plugs and sockets forvoltages lower than 50 V,watertight (IP 67) plugs andsockets, Mondo plugs andsockets as well as plugs andsockets for harsh environ-ments the contacts are nickel-plated. All steel componentssuch as screws and springs

are zinc-plated and blue-chromed or nickel-plated.

Normally CEEtyp plugs andsockets are made of poly-amide. The enclosures ofcombination units are madeof PC/ABS, solid rubber orhard polyethylene.

For special applications likeextreme heat, cold, or to in-crease chemical resistance,

WALTHER also suppliesunits made of special plasticmaterials.

CEE plugs and sockets areconstructed according tothe following standards:

IEC/EN 60 309-1/08.97 andIEC/EN 60 309-2/97DIN/EN 60 309-1/VDE 0623T1: 1993-06DIN/EN 60 309-2/VDE 0623T20: 1993-06

Three different approvalsare applied worldwide:

National Approval

An electrical device isonly submitted for testing inone country and therefore isonly allowed to carry thecertificate of the relevantcountry after successfultesting.

European Approval

The national testingauthorities in Europe foun-ded a European Committeefor electrotechnical standar-disation named CENELEC(CENELEC = Comit Euro-pen de NormalisationElectrotechnique).

Construction and test regulations,

approvals

Conform with Low Voltage

Directive

All members arerequested to transform theCENELEC standards -European Standards (EN) -in national standards withoutany changes. This applies toAustria, Belgium, Denmark,Finland, France, Germany,Great Britain, Greece,Ireland, Italy, Luxemburg,The Netherlands, Norway,

Portugal, Spain, Sweden andSwitzerland. After successfultesting according to the ENstandards in one of the a.m.countries a CCA test reportwill be issued. This reportcan be submitted to everycountry on application for therelevant national standard.

Worldwide valid approvals

All countries in the worldare interested in producing

easily exchangeable goodsbecause of their closebusiness relationships.Therefore the IEC (= Interna-tional Electrotechnical Com-mission) was established.This committee developsIEC Standards on which thetestings of the nationalmember states are based.After successful testing a CBtest report will be establishedwhich can also be used forthe application of national

certificates.
