The function's output signals can be used for direct I/O controlling and user logic programming. The
function generates general time-stamped ON/OFF events to the common event buffer from each of the
two (2) output signal. The time stamp resolution is 1 ms. The function also provides a resettable
cumulative counter for the "Open" operations as well as the ALARM 1 and ALARM 2 events. The
function can also monitor the operations left for each phase.
The following figure presents a simplified function block diagram of the circuit breaker wear function.

Measured input
The function block uses analog current measurement values and always uses the RMS magnitude of
the current measurement input.

Circuit breaker characteristics settings
The circuit breaker characteristics are set by two operating points, defined by the nominal breaking
current, the maximum allowed breaking current and their respective operation settings. This data is
provided by the circuit breaker's manufacturer.
