The Circuit Breaker have recommended life expectancy by ABB
The importance of maintenance Although designed with a life expectancy in excess of 20 years, ABB circuit breakers, like all other industrial products with electromechanical components, can be susceptible to failure over time. The ordinary aging process begins with the commissioning of the circuit-breaker. However, the service age of the circuit breaker is not the only parameter to define the aging of the device. Environment and use are other important factors which can speed up the aging of the device. Maintenance is particularly recommended where the environmental and utilization conditions cause both mechanical and electrical overstressing of the circuit breaker.
