Abstract
A control and actuation device for opening and/or closing an electric switching device having at least one fixed contact and at least one movable contact, which includes an actuating device operatively connected to the movable contact and which supplies energy to perform opening/closure. The actuating device includes a motor with position control, which is operatively connected to the movable contact, and a power and control electronic unit which, following a tripping command, sends to the motor electrical signals for driving the motor so that the movable contact achieves a predefined rule of motion.
