11. Spare parts and accessories
All assembly operations of spare parts/
accessories must be carried out in
accordance with the instructions enclosed
with the spare parts themselves, 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 ensuring that these
interventions are carried out in safe
conditions. If maintenance is carried out by
the customer’s personnel, responsibility for
the interventions remains with the
customer. Before proceeding with any
operation, always make sure that the circuit
breaker is open, the springs discharged and
that it is not energised (medium voltage
circuit and auxiliary circuits).
When ordering 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 nominal current of the circuit breaker
 breaking capacity of the circuit breaker
 serial number of the circuit breaker
 rated voltage of any electrical spare parts.
Please contact our Service office to check on
availability and to order spare parts.
