Functionality

The circuit breaker condition monitoring function (SSCBR) is used to monitor
different parameters of the breaker condition. The breaker requires maintenance
when the number of operations reaches a predefined value. For a proper
functioning of the circuit breaker, it is essential to monitor the circuit breaker
operation, spring charge indication or breaker wear, travel time, number of
operation cycles and estimate the accumulated energy during arcing periods.
