Replacement Circuit Breaker
6.9 MAINTENANCE RECOMMENDATION
The VR-Series
+
circuit breaker is lubricated during assembly with
a long lasting synthetic lubricant. When applied in “usual service
conditions” as defined by IEEE C37.04-1999, the VR-Series
+
circuit
breaker element requires maintenance only once every ten years or
ten thousand operations, which ever comes first.
After a ten year service interval or when ten thousand operations
have been reached, contact your local Eaton representative to
arrange for factory recertification.
During the ten year service interval, no supplemental lubrication with
light machine oil is recommended. Machine oil may be incompatible
with the advanced lubricant in the VR-Series
+
vacuum replacement
circuit breaker and will damage the components of the stored
energy mechanism.
