Factory Authorized Mechanism Enhancement (FAME)
SECTION 3: INSPECTION & MAINTENANCE
m WARNING
DO NOT WORK ON A CIRCUIT BREAKER IN THE 'CONNECT' POSITION.
DO NOT WORK ON A CIRCUIT BREAKER WITH SECONDARY
DISCONNECTS ENGAGED.
DO NOT WORK ON A CIRCUIT BREAKER WITH SPRINGS CHARGED OR
CONTACTS CLOSED.
DO NOT DEFEAT ANY SAFETY INTERLOCKS.
DO NOT LEAVE MAINTENANCE TOOL IN THE SOCKET AFTER CHARGING
THE CLOSING SPRINGS.
m WARNING
STAND AT LEAST ONE METER AWAY FROM THE CIRCUIT BREAKER WHEN
TESTING FOR VACUUM INTEGRITY.
FAILURE TO FOLLOW ANY OF THESE INSTRUCTIONS MAY CAUSE
EQUIPMENT FAILURE, RESULTING IN DEATH, SEVERE PERSONAL INJURY,
EQUIPMENT DAMAGE AND/OR IMPROPER OPERATION. SEE SECTION 2 -
SAFE PRACTICES FOR MORE INFORMATION.
3.1 INSPECTION FREQUENCY
The scheduled maintenance interval of a FAME upgraded power
circuit breaker is 10 years or 10,000 operations, whichever comes
first. However, it is recommended that the circuit breaker be
inspected and cleaned on a regular interval based on the surrounding
ambient conditions. Dust, contaminants and moisture can combine
to create voltage tracking on the surfaces of insulating materials. An
inspection schedule should be created based on the surrounding
ambient conditions. Inspection schedules typically range from 1 to 5
years, but may extend to more or less frequency depending on the
cleanliness of the circuit breaker installation.
A vacuum integrity test should be performed as outlined in the OEM
instruction booklet before the initial installation of a FAME upgraded
circuit breaker and also anytime the circuit breaker is transported
to a new circuit breaker compartment location. Additionally, it is
recommended to inspect the circuit breaker every time it interrupts
fault current.
N
otee:
The OEM instruction booklet contains specific inspection, maintenance
and trouble shooting procedures. Refer to the table in the OEM instruction
manual for maintenance and trouble-shooting.
m WARNING
DO NOT FOLLOW THE LUBRICATION INSTRUCTIONS SHOWN IN THE OEM
INSTRUCTION BOOKLET. THE CIRCUIT BREAKER MECHANISM SHOULD
NEVER BE OILED OR RE-LUBRICATED IN ANY MANOR AFTER THE FAME
UPGRADE IS PERFORMED. THE FAME WARRANTY WILL VOID IF ANY
LUBRICATION IS PERFORMED ON THE CIRCUIT BREAKER THAT HAS THE
FAME PROCESS APPLIED.

SECTION 4: REPLACEMENT PARTS
4.1 GENERAL
The FAME upgrade is achieved with custom engineered sub-
assemblies available only from Eaton's Power Breaker Center
(PBC) and are not required for general maintenance or purchase
for renewal parts. The FAME upgrade and repairs to the FAME
mechanism should only be performed at Eaton's PBC or one of the
Power Breaker Reconditioning centers (PBRc).
m WARNING
DO NOT ATTEMPT TO REPAIR A FAME MECHANISM USING ANY OF THE
RENEWAL PARTS LISTED IN THE OEM INSTRUCTION MANUAL.
In order to minimize production downtime, it is recommended that
an adequate quantity of spare control parts be carried in stock. The
quantity will vary from customer to customer, depending upon the
service severity and continuity requirements. Each customer should
develop their own level based on operating experience. However,
when establishing a new operating record, it is a good practice to
stock one set of control components for every six circuit breakers
of the same control voltage. This quantity should be adjusted with
time and frequency of operation of the circuit breakers. These
components are not included in the FAME upgrade. Refer to the
OEM instruction booklet for replacement control components.
