Inspection and maintenance
5.1 General
4. Qualification of inspection and maintenance personnel
Inspection and maintenance work may only be performed by qualified operator
personnel or by a qualified contracted company. This includes replacement of the
contact system. For more information, see Chapter Maintaining the main contacts
(Page 405).
Siemens offers training measures for performing maintenance on the 3WA circuit
breaker. At the end of the training course, it is possible to take a certification exam.
This training course qualifies participants to maintain the 3WA circuit breaker and to
replace components, thus reducing external maintenance costs and the necessity of
returns.
For more information on this training course, refer to the internet
(https://www.siemens.com/sitrain-lowvoltage).
5. Time required until the circuit breaker or power distribution equipment is ready for
operation
The low inspection and maintenance requirements and the possibility for work to be
performed locally by qualified personnel mean that the circuit breaker and power
distribution equipment are ready to return to operation in a very short time.
