  • the plunger part 89 pushes the finger of the large arm 120 of the pawl 119, ensuring the tilting of the pawl and the release of the respective spouts 117, 118 and therefore the breaking of the toggle joint, authorizing the tilting of the contact carrier 90 towards its open position.
  • the deformation of the bimetallic strip 86 under the effect of an overcurrent causes a thrust of the bimetallic strip on the finger of the short arm 121 of the pawl 119, so that the pawl rocks, causing the toggle to break, and the springs 95 push the movable contacts 92 and the contact carrier 90 into the open position away from the fixed contacts 93.
  • the piece 124 advantageously has a long arm 125 which ensures its repositioning during the movement of the mechanism which follows the breaking of the toggle joint and which is caused by the action of the return spring of the pivoting operating member 110, movement which returns the entire mechanism to its initial rest position in which the contacts are separated, position shown in FIGS. 6 and 9.
