Ordering Replacement Parts
When ordering replacement parts for a Siemens Power
Circuit Breaker, it is very important to give complete infor-
mation. This information should include:
1. Breaker serial number. (On breaker nameplate.)
2. Type of operator. (On operator nameplate.)
3. Type of breaker.
4. Rated continuous current of breaker.
5. Rated voltage of breaker.
6. Description of part. Use instruction book description
insofar as possible.
7. Instruction book number. (On breaker nameplate.)
8. Instruction book reference number.
9. Number of pieces required.
Overhaul
While the breaker can be identified by the serial number
alone, all additional information that is given will serve as
a check to be certain that the part or parts furnished are
correct for the breaker in question. Without this serial num-
ber, Siemens cannot be sure of the correct identity of the
desired parts.
If any doubt exists as to the instruction book reference num-
ber or the description, a dimensional sketch of the desired
part will help to properly identify it.
Siemens recommends that a supply of repair parts be kept
on hand so that emergency repairs can be made without
waiting for shipment of parts from the factory. A list of
recommended spare parts is sent with the breaker.
Before removing any part to be replaced, observe its func-
tion and adjustment. This usually saves adjustment time
during installation.
