ELECTROMECHANICAL ELEMENTARY RELAYS –

Part 10: Additional functional aspects and safety
requirements for high-capacity relays

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.
The International Standards of the IEC 61810 have been prepared by IEC technical committee
94: All-or-nothing electrical relays.
The text of this International Standard is based on the following documents:
FDIS Report on voting
94/453/FDIS 94/458/RVD

Full information on the voting for the approval of this International Standard can be found in
the report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

elementary relays, can be found on the IEC website.
This International Standard is to be used in conjunction with IEC 61810-1:2015.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

ELECTROMECHANICAL ELEMENTARY RELAYS –

Part 10: Additional functional aspects and safety
requirements for high-capacity relays



1 Scope
This part of IEC 61810, with functional and safety aspects, applies to electromechanical
elementary relays (non-specified time all-or-nothing relays) with high capability requirements
like breaking or short circuit capabilities and similar for incorporation into low-voltage
equipment. These relays may have a specific design to extinguish the electric arc between
contacts (e.g. by magnetic blow-out), or use an insulation coordination not covered by
IEC 61810-1 (e.g. by gas filled contact chambers), or require safety assessments not covered
by IEC 61810-1 (e.g. for higher loads).
It defines additional requirements for high-capacity relays with generic performance intended
for use in applications in smart grids, electric vehicles and other applications where, for
example, battery charge/discharge switching is used, such as:
• electrical energy storage (EES) systems,
• solar photovoltaic energy systems,
• electric road vehicles (EV) and electric industrial trucks,
• power electronic systems and equipment,
• secondary cells and batteries,
• road vehicles.
Compliance with the requirements of this standard is verified by the type tests indicated.
