Functionality
The circuit breaker condition monitoring function 52CM 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
exceed the threshold settings.
The function contains a blocking functionality. It is possible to block the function outputs,
if desired.
