Functionality
The circuit-breaker condition monitoring function SSCBR is used to monitor different
parameters of the circuit breaker. The breaker requires maintenance when the number
of operations has reached a predefined value. The energy is calculated from the
measured input currents as a sum of I
calculated values exceed the threshold settings.
The function contains a blocking functionality which can be used to block the function
outputs.
Analog input configuration
SSCBR has one analog group input which must be properly configured.
