  • This first spring arrangement 5 is a spring helical coaxial to the operating rod 1 and one of which end is supported on a first fixed part 12 and the other end is supported on the first slide 4, this first spring 5 being kept compressed in the position the circuit breaker is engaged by the first control means 6 consisting of a retractable means for retaining the first slide 4.
  • This retaining means 6 is a hooking member cooperating with a flange 15 formed on the first slide 4 and actuated by a trip coil 16.
  • the control end 2 of the operating rod 1 is linked to the tubular rod 3 by at least part projection 7 fixed to the operating rod 1 and passing through respectively a longitudinal light 8 arranged on the tubular rod 3 and the control device comprises a second slide 9 said to be interlocked to which the operating rod 1 by its projecting part 7 and subjected to a second arrangement of spring 10 said to engage moving from the triggered position to the engaged position of the circuit breaker under the action of a second control means 11 actuated during an engagement.
  • This second spring arrangement 10 is a spring helical coaxial with the tubular rod 3 and one of which end is supported on a second fixed part 13 and the other end is supported on the second slide 9 to which the operating rod 1 is fixed by through its protruding part 7, this second spring 10 being kept compressed in the triggered position of the circuit breaker by the second control means 11 constituted a retractable means for retaining the second slide 9.
  • This retaining means 11 is a hooking member cooperating with a flange 17 formed on the first slide 4 and actuated by a latching coil 18.
  • the device In the position shown in Figure 1A, the device is in the engaged position.
  • the first slide 4 pushed by the rod 3 actuated by the solenoid 14 and by the second slide 9 pushed by the spring 10 is retained by the fastening member 6.
  • the free spring 10 pushes the second slide 9 and therefore the end 2 of the rod operation 1 in the engaged position.
  • the trigger coil 16 When triggered as shown in the figure 1B, the trigger coil 16 is actuated and releases the spring 5 which pushes the first slide 4 as well as the rod 3 released by the solenoid 14 and the second slide 9 driving the end 2 of the operating rod 1 in triggered position.
  • the flange 17 of the second slide 9 is blocked by the attachment member 11.
  • the device is then in position to be re quickly engaged by releasing the flange 17 of the second slide 9 in order to return to the engaged position shown in Figure 1A.
  • the first trigger spring 5 develops a effort greater than that developed by the second spring said 10 and these springs are therefore dimensioned result.
  • Figures 2A, 2B and 2C show a second alternative embodiment of the device according to the invention where the spring arrangements 5, 10 are constituted of snap-action organs with respect to a position of imbalance called neutral.
  • the first spring arrangement 5 consists of two telescopic rods 50, 50 ′ whose longitudinal axes are in the same plane, connected at one of their ends in opposite the first slide 4 by respectively a pivoting link 51, 51 'of the yoke type and the other of which end is pivotally fixed at a fixed point 52, 52 ', a spring 53, 53' surrounding the rod 50, 50 'being compressed between the yoke 51, 51 'and the fixed end.
  • the first control means 6 is a thrust of the first slide 4. This thrust member is a rod 6 actuated by a trip coil 16.
  • the second spring arrangement 10 consists of two telescopic rods 100, 100 'whose axes longitudinal are in the same plane, connected to one of their ends opposite the second slide 9 by respectively a swivel link 101, 101 'of the yoke type and the other end of which is pivotally attached in a fixed point 102, 102 ', a spring 103, 103' surrounding the rod 100, 100 'being compressed between the yoke 101, 101' and the fixed end.
  • the second control means 11 is a thrust of the second slide 9. This thrust member is a rod 11 actuated by a trigger coil 18.
  • the device In the position shown in Figure 2A, the device is in the engaged position.
  • the first slide 4 is pushed by the rod 3 actuated by the solenoid 14.
  • the spring arrangement 10 pushes the second slide 9 and so the end 2 of the operating rod 1 in position engaged.
  • a flange 17 formed on the second slide 9 abuts against a fixed element non visible. So there is free space on the one hand between the slides 4, 9 and between the projecting part 7 and the end of the light 8.
  • the first spring arrangement 5 is in a position very close to its neutral position corresponding to a vertical and aligned position of the rods 50, 50 'in the figure.
  • the trigger coil 16 When triggered as shown in the figure 2B, the trigger coil 16 is actuated and drives the outlet of the rod 6 which pushes the spring arrangement 5 and the rod 3 released by the solenoid 14. This is done easily on the aforementioned free space and after this push, spring arrangement 5 has exceeded its point position dead and acts on its own to push rod 3 and the second slide 9 driving the end 2 of the rod operation 1 in the tripped position.
  • the second flange 17 slide 9 comes to bear on rod 11 of the coil 18. In this position, it is the second spring arrangement 10 which is in a very position close to its neutral position corresponding to a vertical and aligned position of rods 100, 100 'on the figure.
  • the device is then in position to be re quickly engaged by pushing rod 11 of the coil engagement 18 of the second slide 9 in order to return to the engaged position shown in Figure 2A.
  • the first arrangement of spring called trigger 5 develops a greater effort than that developed on second arrangement of spring said to engage 10 and these spring arrangements are therefore dimensioned in result.
