Resolution:
Life expectancy for molded case circuit breakers in the industry is generally expected to be about 30 years, given favorable environment and regular maintenance. Required maintenance, especially for older breakers, includes annual exercising—OFF, ON, TRIP, RESET, ON. This will help to ensure that the mechanism remains operable. Conditions of service, including number of on-off cycles, number of load operations, overloads, short circuits, environmental conditions, and maintenance may affect the time of useful service.
See the attached maintenance guides for more information.
