Abstract (en)
A modular auxiliary electrical device, particularly for minimum operating voltage control, includes a casing adapted to be associated with an electrical device, such as a circuit breaker, and includes an electrical connection means for connection to conducting components. The electrical connection means are connected to a kinematic system which is adapted to act on the associated electrical device. The auxiliary device includes a lever which is rigidly coupled to a movable portion of an armature of a relay and is suitable to actuate the kinematic means when the value of the supply voltage drops below a preset value. <IMAGE>
