Blocking of the Tripping by Device-Internal Inrush-Current Detection

6.3.7
6.3.7.1

Description

With the Blk. w. inrush curr. detect. parameter, you can define whether tripping of the stage
should be blocked when a threshold value is exceeded due to an inrush current. In case of a blocking, the
stage picks up. The start of the tripping delay and the trip signal are blocked. The function signals this through
a corresponding indication. If the blocking drops out and the threshold value of the stage is still exceeded, the
time delay is started. After that time, the stage operates. The following figure only shows the part of the stage
(exemplified by definite-time overcurrent protection stage 1) that illustrates the influence of the blocking.
Only if the central function Inrush-current detection (see chapter
can the blocking be set.
