This setpoint adjusts the reaction time of the IDMT overcurrent protection if
the overcurrent level is 200% of the nominal current.
The reaction time of the IDMT overcurrent protection is not fixed; it depends
on how much is the actual current above the limit (nominal). The higher is the
overcurrent the shorter the reaction time will be.
EXAMPLE OF IDMT OVERCURRENT PROTECTION CURVE
NOTE:
When the IDMT protection is activated the MCB is opened and the event is
recorded in the Alarmlist and History. The further MCB closing is blocked
until Fault Reset has been pressed to clear the alarm.
