Abstract
A switch unit includes a current switching device drivable by an electromagnetic actuator for opening/closing an electric circuit associated with the switch unit, a first energy storage for storing electric energy for the electromagnetic actuator, and electronic controller means which are supplied by an external power line and control a supply of the electric energy from the energy storage means to the electromagnetic actuator. The switch unit includes emergency procedure operating means associated with the electronic controller means and provided with a second energy storage means. The emergency procedure operating means are configured for enabling driving of the current switching device and opening the associated electric circuit in an emergency condition in which a lack or drop or irregular supply of the external power line is experienced.
