3.10 Activation status of protective functions
Which protective functions are activated in the circuit breaker can be indicated and evaluated
in the register "Activation status of protective functions".
Protective functions that require a voltage tap have a second data point. This indicates
whether the necessary voltage tap is present.
Example: Protective function "Undervoltage protective function ON" with second data point
"Overvoltage protective function active".
