Abstract
A device for the actuation of the movable contacts of a hybrid circuit breaker allows the following time diagram to be implemented: command the opening of the interrupting chamber, offset the opening of the vacuum switch so as to allow the interrupting chamber contacts to separate at a minimum speed and in a way that is synchronous with the separation of the vacuum switch contacts, close the vacuum switch while keeping the interrupting chamber in the open position. Moreover, closing the interrupting chamber does not act upon the contacts of the vacuum switch.
