*)
This is the instantaneous time i.e. the minimum total operational time including the fault
detection time and operation time of the trip contacts.

Arc protection (option)

The operation of the arc protection depends on the setting value
of the ArcI> current limit. The current limit cannot be set,
unless the relay is provided with the optional arc protection
card.
