Abstract

Electric circuit breaker with adjustable trigger device; comprising: a relatively fixed electromagnet, an armature with loose adjustment rotatable about a predetermined axis of rotation; first elastic action means acting on said reinforcement and springing it for rotation in a direction that separates from said electromagnet; stopping means limiting the rotation of said armor in its separation from said electromagnet; second elastic means of action on said reinforcement; means for regulating the line of action of said second elastic means between a first position in which said line of action passes through said axis of rotation of said reinforcement and a second position in which said line of action passes to a side of said axis of rotation; and elements for adjusting the magnitude of the action of said first and second elastic means.
