This publication contains the information required
to install DCBreak high speed DC circuit breakers
and put them into service. Please read the manual
carefully to ensure that the product is used
correctly.
Similarly to all the apparatus we manufacture,
DCBreak circuit breakers are designed for different
configurations. They can also be used for special
technical-construction solutions designed for the
customer on request.
The manual may not contain instructions concerning
these special customized configurations.
Consequently, besides this manual, it is always
necessary to consult the technical documentation of
the specific job order (circuit diagrams,
topographical diagrams, assembly and installation
drawings, etc.) regarding any non-standard
configurations requested.
Doubts concerning the interpretation of the
contents of this document or the need for further
information should be submitted to your ABB
representative in order to obtain the necessary
explanations before proceeding.
Only use original spare parts for maintenance work.
Consult the list of spares enclosed with this manual
and the spare parts catalog for further details.
All installation, putting into service,
operation and maintenance work must be
carried out by suitably qualified personnel
with in-depth knowledge of the apparatus.
1.1. Environmental protection
program
DCBreak circuit breakers are manufactured in
accordance with ISO 14000 Standards (Guidelines
for environmental management). Fully recyclable
materials are used since particular care is paid to
EoL management of the product.
Qualified personnel
All installation, putting into service, operation and
maintenance work must be carried out by suitably
qualified personnel with in-depth knowledge of the
apparatus.
The tasks described in this manual must only be
performed by qualified personnel who possess
authorizations enabling them to work on
electromechanical equipment and who are aware of
the electrical hazards (dangerous voltage) and
mechanical hazards (moving parts) relating to work
on electric circuit breakers. The workers must also
be familiar with the use of personal protective
equipment.
1.2. Regulatory framework and
applicable legislation
DCBreak circuit breakers conform to the
requirements of the regulations applicable to the
sector concerned. In detail:
•
IEC 60077-1-2-3 Railway applications - Electric
equipment for rolling stock:
electrotechnical components
•
IEC 61373
Railway applications - Electric
equipment for rolling stock:
shock and vibration tests
•
EN 45545-2
Conformity of insulating parts to
the reaction to fire and smoke
classification
Installation and maintenance operations performed
by the customer must comply with the local
regulations and legislation governing labor safety
and electrical installations with dangerous voltage.
