Why the energy storage switch trips

When the closing spring releases energy (the switch is just closed), the mechanism starts to store energy for the closing spring, which takes about 10 seconds. At this time, even if the switch is closed in case of fault, because the opening spring has stored energy, it can be disconnected.
