Switching onto a
To perform an instantaneous trip when the circuit breaker is manually closed onto a
Fault
dead fault, the manual closing command of the control discrepancy switch can be fed
to the device via a binary input. The overcurrent protection can then trip three-pole
without delay or with a reduced delay. It can be determined via parameter setting for
which stage(s) the rapid tripping following manually closure on to a dead fault applies
(refer also to the logic Figures 2-117, 2-118 and 2-119).
Pickup and Trip-
The pickup signals of the individual phases (or the earth) and of the stages are linked
ping Logic
in such a way that both the phase information and the stage which has picked up are
indicated (Table 2-12).
In case of trip signals, the stage which resulted in the trip command is also indicated.
For single-pole tripping, the pole is identified (see also Section 2.23.1 „Pickup Logic of
the Entire Device").
