ABB REG670 - Functionality

16.4.2 Functionality
The breaker 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.
