Closing/opening switch for inductive energy storage applications
A magnetically delayed vacuum switch operating sequentially in a closing mode and then in an opening mode enables the design of a compact electron-beam generator based on an inductive energy store and having only a single switch. Furthermore, the system can be entirely vacuum insulated, with no power feedthrough requiring low inductance or operating at high-impulse

Principle of Energy Storage Switch | Nader Circuit Breaker
The so-called energy storage means that when the circuit breaker is de-energized (that is, when it is opened), it opens quickly due to the spring force of the energy storage switch. Of course, the faster the circuit breaker is opened, the better. This is to have enough power to separate the contacts when the segmentation fault has a large current (excessive current will melt the
