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 specifications, 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 60077-3 has been prepared by IEC technical committee 9: Electric
railway equipment.
The text of this standard is based on the following documents:
FDIS Report on voting
9/651/FDIS 9/666/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.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
This standard should be read in conjunction with IEC 60077-1 and IEC 60077-2.
Annex A forms an integral part of this standard.
Annex B is given for information only.

RAILWAY APPLICATIONS –
ELECTRIC EQUIPMENT FOR ROLLING STOCK –
Part 3: Electrotechnical components –
Rules for d.c. circuit-breakers
1 Scope and object
In addition to the general requirements of IEC 60077-2, this part of IEC 60077 gives the rules
for circuit-breakers, the main contacts of which are to be connected to d.c. power and/or
auxiliary circuits. The nominal voltage of these circuits does not exceed 3 000 V d.c. according
to IEC 60850.
This part of IEC 60077, together with IEC 60077-2, states specifically
a) the characteristics of the circuit-breakers;
b) the service conditions with which circuit-breakers have to comply with reference to
– operation and behaviour in normal service;
– operation and behaviour in the case of short circuit;
– dielectric properties;
c) the tests for confirming the compliance of the components with the characteristics under
the service conditions and the methods to be adopted for these tests;
d) the information to be marked on, or given with, the circuit breaker.
NOTE 1 Circuit-breakers which are dealt with in this part of IEC 60077 may be provided with devices for automatic
opening under predetermined conditions other than those of over-current, for example, under-voltage and reversal
of power current. This part of IEC 60077 does not deal with the verification of operation under such predetermined
conditions.
NOTE 2 The incorporation of electronic components or electronic sub-assemblies into electrotechnical components is
now common practice.
Although this standard is not applicable to electronic equipment, the presence of electronic components does not
provide a reason to exclude such electrotechnical components from the scope.
Electronic sub-assemblies included in circuit-breakers should comply with the relevant standard for electronics
(IEC 60571).
NOTE 3 Certain of these rules may, after agreement between the user and the manufacturer, be used for electro-
technical components installed on vehicles other than rail rolling stock such as mine locomotives, trolleybuses, etc.
In this case, particular additional requirements may be necessary.
This standard does not cover
a) multi-connection of electro-technical components to achieve a particular duty;
b) industrial circuit-breakers which have to comply with IEC 60947-2;
c) d.c. circuit-breakers for fixed installations which have to comply with IEC 61992-2.

---------------------- Page: 12 ----------------------

SIST EN 60077-3:2003
60077-3 © IEC:2001 – 13 –
For b) and c), in order to ensure satisfactory operation, this standard should be used to specify
only the particular requirements for rolling stock. In such cases, a specific document should
state the additional requirements with which the industrial or fixed installations circuits breakers
are to comply, for example:
– either to be adapted (for example, for control voltage, environmental conditions, etc.);
– or to be installed and used in such a way that they do not have to endure specific rolling
stock conditions;
– or to be additionally tested to prove that these components can withstand satisfactorily the
rolling stock conditions.
2 Normative references
The following normative documents contain provisions which, through reference in this text,
constitute provisions of this part of IEC 60077. For dated references, subsequent amendments
to, or revisions of, any of these publications do not apply. However, parties to agreements
