Abstract (en)
A medium-voltage circuit-breaker including, inside an envelope filled with a dielectric gas, a cutoff chamber containing a stationary main contact, a moving main contact and a first volume in the vicinity of a stationary arc contact and of a moving arc contact, includes a second volume (V3) adjacent to the said first volume (V2) and associated with means (14B, 16) for placing the said first and second volumes in communication only when the value of the current to be cut off reaches, during a triggering manoeuvre, a given threshold value. Application to medium-voltage circuit-breakers. <IMAGE>
