Abstract

The apparatus has a control lever (8) controlling a fixed contact and a movable contact (6) between spacing and contact positions. A return unit is connected to the lever to move a connecting rod end (3b) toward a rotation axis of the lever along a path external to a trip device (4)/contact carrier assembly. A protuberance (2) on the path blocks an assembly of the rod/lever in a middle position to signal tripping of a lock following an electric fault. The protuberance is partially retractable and/or deformable when a force exerted on the lever is greater than that on the return unit.
