FOREWORD
1) The IEC (International Electrotechnical Commission) is a world-wide 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 62019 has been prepared by subcommittee 23E: Circuit-breakers
and similar equipment for household use, of IEC technical committee 23: Electrical accessories.
The text of this standard is based on the following documents:
FDIS Report on voting
23E/363/FDIS 23E/366/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.
Annexes B, C and D are for information only.

CIRCUIT-BREAKERS AND SIMILAR EQUIPMENT
FOR HOUSEHOLD USE –
AUXILIARY CONTACT UNITS
1 Scope and object
This International Standard applies to auxiliary contact units associated (or intended to be
associated) with circuit-breakers for overcurrent protection, and with residual current operated
circuit-breakers with or without integral overcurrent protection for household and similar
installations, having a rated voltage not exceeding 440 V a.c. and 250 V d.c., and a rated
current not exceeding 10 A.
NOTE 1 – These requirements may also be used as guidance for auxiliary contacts units intended to be assembled
with other switching devices for household and similar installations.
NOTE 2 – It is recommended that the advice of the manufacturer be sought concerning any application with low
level energy appliances (low level values of current and/or voltage.) For low-energy contacts, specific
recommendations are given in IEC 60947-5-4.
The object of this standard is to state
a) the characteristics of the auxiliary contact units;
b) their electrical and mechanical requirements with respect to
1) the various duties to be performed;
2) the significance of the rated characteristics and of the markings;
3) the tests to verify the rated characteristics;
c) the functional requirements to be satisfied by the auxiliary contact units with respect to
1) environmental conditions, including those of enclosed equipment;
2) dielectric properties;
3) terminals;
4) safety of use.
2 Normative references
The following normative documents contain provisions which, through reference in this text,
constitute provisions of this International Standard. For dated references, subsequent
amendments to, or revisions of, any of these publications do not apply. However, parties to
agreements based on this International Standard are encouraged to investigate the possibility
of applying the most recent editions of the normative documents indicated below. For undated
references, the latest edition of the normative document referred to applies. Members of IEC
and ISO maintain registers of currently valid International Standards.
