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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 61076-2 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.
This International Standard is to be used in conjunction with IEC 61076-1:2006.

1 Scope
This part of IEC 61076 establishes uniform specifications and technical information for circular
connectors. This document is to be used in conjunction with the generic specification
IEC 61076-1 for product requirements as the basis for preparation of detail product
specifications for circular connectors.
NOTE The quality assessment requirements for connectors whose product requirements are given in IEC 61076
series are detailed in IEC 62197-1. This can be used as the basis for preparation of detail quality assessment
specifications for circular connectors.
In the event of conflict between this sectional product specification and the detail product
specification, it is intended that the requirements of the detail product specification prevail.

4 Technical information
4.1 System of levels
4.1.1 General
Subclauses 4.1.2 and 4.1.3 provide information about performance and compatibility levels
(respectively).
4.1.2 Performance levels
If appropriate, the detail product specification shall contain information about the different
performance levels.
The term 'performance level' reflects the grouping of the environmental and mechanical
stresses at which a component is tested, and also such features as long-term stability of
electrical characteristics. If different levels are defined in the detail product specification, they
shall be numbered, where the lowest number (1) usually indicates the highest performance.
4.1.3 Compatibility levels
As a function of the standardization degree, four levels characterize the compatibility of
connectors from different sources. These levels are defined in IEC 61076-1 and shall be
indicated in the detail product specification of circular connectors.
4.2 Classification into climatic categories
Unless impractical, the lower and upper temperatures and the duration of the damp heat, steady
state test should be described in a table similar to the example given in IEC 61076-1.
For a correct assignment of climatic category, the correct relationship between the upper
category temperature (UCT) and the upper limiting temperature (ULT) of a connector (implied
in the derating diagram(s) discussed in 4.4), as well as between the lower category temperature
(LCT) and the lower limiting temperature (LLT) of a connector should be considered (see
IEC 61984 relevant definitions).
4.3 Clearance and creepage distances
Permissible working or rated voltages depend on the connector end-use application and on the
applicable or specified safety requirements.
Clearance and creepage distances as well as proof voltages under specified air pressure shall
be specified in the detail product specification, based on the assigned rated insulation
voltage(s). See IEC 61984, IEC 60664-1 or IEC TR 63040, as applicable.
4.4 Current-carrying capacity
For each connector, the current-carrying capacity for the declared wire size (typically the
maximum) shall be specified in the detail product specification. It is preferable that the derating
curve for the relevant wire size, determined in accordance with test 5b of IEC 60512-5-2 is
prepared. Alternatively, it is allowed to provide only one value of rated current for a specified
wire size at a specified temperature as described in IEC 60512-5-1.
IEC 61076-2:2025 © IEC 2025
NOTE 1 The derating curve(s) can be provided in either graphic form or in mathematical form with the formula or
both:
0,5
t

II ×−1

where
I = working current at ambient temperature t;

(t)
I = working current at 0 °C (intersection with y-axis);

(0 °C)
t = ambient temperature;
ULT = upper limiting temperature (intersection with x-axis ≥ UCT (upper category temperature)
NOTE 2 The basic diagram determined in accordance with test 5b of IEC 60512-5-2 is then verified by a
temperature rise test 5a of IEC 60512-5-1
4.5 Marking
Each connector and its associated package shall be marked in accordance with the
requirements specified in IEC 61076-1.
