Abstract (en)
A control device for circuit breakers comprises a casing which can be coupled to an electrical device, such as a residual current operated circuit breaker provided with a control for opening and closing the contacts. The casing comprises a drum, which is kinematically associated with the control for opening and closing the contacts of the circuit breaker. The control device includes a single electric motor, which is adapted to actuate a gear train by means of a worm screw. The gear train is suitable to turn the drum in one direction or the other by a rotation switching means.
