2.7.2 Parameter settings
The values that can be set are determined by the basic device
setting selected on the Basic Settings Block. The following table
shows the parameter allocation in dependence on the variant
ordered and the operating mode selected by the Basic Settings
Block:
Determining the setting values
The high-current stage I>> is used for fast tripping that does not
depend on any selective tripping schedule; it is mainly used for
