Spare Parts And Accessories - ABB VD4 36 Installation And Service Instructions Manual

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 60694)
and of all the Standards aimed at carrying out
these interventions 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 discharged 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 normal current of the circuit-breaker
– breaking capacity of the circuit-breaker
– serial number of the circuit-breaker
– rated voltage of any electrical spare parts.
For availability and to order spare parts, please contact our
Service office.
