11. Spare parts and accessories
All assembly operations of spare parts/accessories
must be carried out following the instructions
enclosed with the spare parts, by ABB personnel
or by suitably qualified customer personnel
with in-depth knowledge of the apparatus (IEC
62271) and of all the Standards aimed at ensuring
that these interventions are carried out in safe
conditions. Should the maintenance be carried out
by the customer's personnel, responsibility for the
interventions remains with the customer. Before
carrying out any operation, always make sure that
the circuit-breaker is open, the spring released and
that it is not energised (medium voltage circuit and
auxiliary circuits).
To order circuit-breaker spare parts/accessories, refer to the
ordering sales codes indicated in the technical catalogue and
always state the following:
– type of circuit-breaker
– rated voltage of the circuit-breaker
– rated thermal current of the circuit-breaker
– breaking capacity of the circuit-breaker
– serial number of the circuit-breaker
– rated voltage of any electrical spare parts.
