Figure 6-6 Structure/Embedding the Function Overcurrent Protection, Phases – Basic
If the device-internal functions listed in the following are present in the device, these functions can influence
the pickup values and tripping delays of the stages or block the stages. The stage can also be affected by an
external source via a binary input signal.
•
Automatic reclosing (AREC)
•
Cold-load pickup detection
•
Binary input signal
If the device is equipped with an Inrush-current detection function, the stages can be stabilized against trip-
ping due to transformer-inrush currents (available in both function types).
