Maintenance and lubrication
This section provides recommended information for Citadel circuit breaker and cell
lubrication.
This information is based upon the Citadel circuit breaker operating under “usual service
conditions” as per ANSI / IEEEC 37.20.2, section 4 (for drawout circuit breakers) or ANSI /
IEEE C37.04.
This information is based upon the Citadel circuit breaker operating in clean environments.
Maintenance and lubrication intervals are based on the number of closing operations or
the time interval since last maintenance whichever occurs first.
Generally seven (7) years or 2000 operations should be scheduled as maintenance cycle
points.
Any fault operations that impinge upon VI life curves boundaries should be scheduled as
maintenance cycle points.
Clean the entire stored-energy operator mechanism and the connector points of often
moving parts with a dry, lint-free cloth. Using compressed air (such as a keyboard cleaner)
can be a useful assistant.
Carefully check all components for evidence of noticeable wear. Pay additional attention to
the closing spring-crank and the insulating couplers and linkages as they see much of the
mechanical forces of operation.
For all lubrication (except electrical moving or sliding surfaces), use one of the following:
TIMKEN Fleetultra Grease (olive green).
CRC® Power Lube® (spray) (part 03045).
