Figure 2-107 Breaker tripping alarm suppression
If the device issues a final trip command, the contact remains closed. This is the case, during the reclaim time
of the automatic reclosure cycle, when the automatic reclosure is blocked or switched off or, due to other
reasons is not ready for automatic reclosure (e.g. tripping only occurred after the action time expired).
Figure 2-108 shows time diagrams for manual trip and close as well as for short-circuit tripping with a single,
failed automatic reclosure cycle.
