PLUGS, SOCKET-OUTLETS AND COUPLERS FOR INDUSTRIAL PURPOSES –
Part 1: General requirements
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. Their preparation is
entrusted to technical committees; any IEC National Committee interested in the subject dealt with may
participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization
for Standardization (ISO) in accordance with conditions determined by agreement between the two
organizations.
2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60309-1 has been prepared by subcommittee 23H: Industrial plugs
and socket-outlets, of IEC technical committee 23: Electrical accessories.
This fourth edition cancels and replaces the third edition published in 1997 and constitutes a
technical revision.
The text of this standard is based on the following documents:
FDIS Report on voting
23H/88/FDIS 23H/91/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
Annex A forms an integral part of this standard.

INTRODUCTION
International Standard IEC 60309 is divided into several parts:
Part 1: General requirements, comprising clauses of a general character.
Subsequent parts: Particular requirements dealing with particular types. The clauses of these
particular requirements supplement or modify the corresponding clauses in part 1. Where the
text of subsequent parts indicates an "addition" to or a "replacement" of the relevant
requirement, test specification or explanation of part 1, these changes are made to the relevant
text of part 1, which then becomes part of the standard. Where no change is necessary, the
words "This clause of part 1 is applicable" are used.
60309-1 IEC:1999 – 9 –
PLUGS, SOCKET-OUTLETS AND COUPLERS FOR INDUSTRIAL PURPOSES –
Part 1: General requirements
1 Scope
This standard applies to plugs and socket-outlets, cable couplers and appliance couplers, with
a rated operating voltage not exceeding 690 V d.c. or a.c. and 500 Hz a.c., and a rated current
not exceeding 250 A, primarily intended for industrial use, either indoors or outdoors.
The list of preferred ratings is not intended to exclude other ratings, requirements for which are
under consideration.
This standard applies to plugs and socket-outlets, cable couplers and appliance couplers,
hereinafter referred to as accessories, for use when the ambient temperature is normally within
the range of –25 °C to +40 °C. These accessories are intended to be connected to cables of
copper or copper alloy only.
The use of these accessories on building sites and for agricultural, commercial and domestic
applications is not precluded.
Socket-outlets or appliance inlets incorporated in or fixed to electrical equipment are within the
scope of this standard. This standard also applies to accessories intended to be used in extra-
low voltage installations.
This standard does not apply to accessories primarily intended for domestic and similar general
purposes.
In locations where special conditions prevail, for example on board ship or where explosions
are liable to occur, additional requirements may be necessary.
2 Definitions
Where the terms voltage and current are used, they imply the d.c. or the a.c. r.m.s. values.
For the purpose of this part of IEC 60309, the following definitions apply.
The application of accessories is shown in figure 1.
2.1
plug and socket-outlet
a means enabling the connection at will of a flexible cable to fixed wiring. It consists of two
parts:
60309-1 IEC:1999 – 11 –
2.1.1
socket-outlet
the part intended to be installed with the fixed wiring or incorporated in equipment.
A socket-outlet may also be incorporated in the output circuit of an isolating transformer
2.1.2
plug
the part integral with or intended to be attached directly to one flexible cable connected to the
equipment or to a connector
2.2
cable coupler
a means enabling the connection at will of two flexible cables. It consists of two parts:
2.2.1
connector
the part integral with or intended to be attached to one flexible cable connected to the supply
NOTE – In general, a connector has the same contact arrangement as a socket-outlet.
2.2.2
plug
the part integral with or intended to be attached to one flexible cable connected to the
equipment or to a connector
NOTE – The plug of a cable coupler is identical to the plug of a "plug and socket-outlet".
2.3
appliance coupler
a means enabling the connection at will of a flexible cable to the equipment. It consists of two
parts:
2.3.1
connector
the part integral with, or intended to be attached to, one flexible cable connected to the supply
NOTE – In general, the connector of an appliance coupler is identical to the connector of a cable coupler.
2.3.2
appliance inlet
the part incorporated in, or fixed to, the equipment or intended to be fixed to it
NOTE – In general, an appliance inlet has the same contact arrangement as a plug.
2.4
rewirable plug or connector
an accessory so constructed that the flexible cable can be replaced
2.5
non-rewirable plug or connector
an accessory so constructed that the flexible cable cannot be separated from the accessory
without making it permanently useless
2.6
mechanical switching device
a switching device designed to close and open one or more electric circuits by means of
separable contacts
60309-1 IEC:1999 – 13 –
2.7
switched socket-outlet
a socket-outlet with an associated switching device to disconnect the supply from the socket-
outlet contacts
2.8
integral switching device
a mechanical switching device constructed as a part of an accessory covered by this standard
2.9
interlock
a device, either electrical or mechanical, which prevents the contacts of a plug from becoming
live before it is in proper engagement with a socket-outlet or connector, and which either
prevents the plug from being withdrawn while its contacts are live or makes the contacts dead
before separation
2.10
retaining device
a mechanical arrangement which holds a plug or
