Part 2-116: Detail specification for circular connectors
size 15 with up to 3+PE power contacts and auxiliary
contacts, with bayonet-locking

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of 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, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). 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. 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 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 IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
IEC 61076-2-116 has been prepared by subcommittee 48B: Electrical connectors, of IEC
technical committee 48: Electrical connectors and mechanical structures for electrical and
electronic equipment. It is an International Standard.
The text of this International Standard is based on the following documents:
Draft Report on voting
48B/3000/FDIS 48B/3010/RVD

Full information on the voting for its approval can be found in the report on voting indicated in
the above table.

CONNECTORS FOR ELECTRICAL AND ELECTRONIC
EQUIPMENT – PRODUCT REQUIREMENTS –

Part 2-116: Detail specification for circular connectors
size 15 with up to 3+PE power contacts and auxiliary
contacts, with bayonet-locking



1 Scope
This part of IEC 61076-2 specifies circular connectors size 15 with bayonet-locking, with up to
3 power contacts with rated insulation voltage up to 630 V AC/DC and rated current up to 20 A,
plus PE, and up to 3 auxiliary contacts with rated insulation voltage up to 63 V AC/DC and rated
current up to 10 A, that are typically used for industrial power supply and power applications,
such as the feeding and control of 3-phase asynchronous motors. These connectors consist of
both fixed and free connectors either rewireable or non-rewireable, with bayonet-locking. Male
connectors have round contacts, either power or signal, Ø1,6 mm.
NOTE 1 Size 15 is the dimension of the inner contact carrier of the male connector interface (dimension AG in
Table 18).
NOTE 2 Number of power and auxiliary contacts, voltage and current ratings vary according to the type of connector,
see Table 1.
