  • the trigger pin 28 is secured to the lever of the trigger 76, extending parallel to the drive tab 20.
  • the rotary plate 74 can rotate around a pivot 78 between two positions extremes, and the trigger lever 76 is articulated on an axis 80 integral with the plate 74.
  • the movable contacts 42, 44 are shaped according to metal blades flexible, actuated by a pair of operating levers 82, 84 bistable cooperating with springs 86, 88 housed in guide members 90.92.
  • a pair of control rods 94, 96 cooperating at their ends opposite respectively with a stop 55 of the housing 12 (OF) or the handle 54 (SD) and the plate 74.
  • the other operating lever 84 of the movable contact 44 associated with the first inverter circuit 38 is pivotally mounted on pivot 78 so as to be driven by the rotary plate 74 between the two extreme positions.
  • the end bent rod 96 moves into an oblong hole 98 in the area of articulation with the lever 82.
  • the operation of the auxiliary signaling unit 10 in OF-OF version is shown in FIGS. 4 to 10.
  • the internal handle 54 in this case comprises a first configuration of the profile 54A allowing the control rod 94 to come to bear on the stop 55 of the housing 12.
  • the signaling unit 10 being in the closed state (FIG. 4), the movable contact 42 is in engagement against the fixed contact 46, and the other movable contact 44 is in press on the fixed contact 50.
  • the auxiliary signaling unit 10 is actuated by the tab drive 20 of the second mechanical link 18, causing movement of tilting of the handle 54 in an anticlockwise direction.
  • the Figure 5 shows the mechanism 40 in the vicinity of the dead center of the two levers operation 82, 84.
  • the two movable contacts 42, 44 are driven towards a position separation median with the corresponding fixed contacts.
  • the shift from neutral to the two levers 82, 84 causes the simultaneous switching of the two movable contacts 42, 44, which arrive respectively against the fixed contact 48 of the reversing circuit 36, and the fixed contact 52 of the inverter circuit 38.
  • the auxiliary signaling unit 10 also delivers two signals representative of the open state of the circuit breaker 14.
  • the manual closing operation of the auxiliary signaling unit takes place in reverse of Figures 4 to 6 after actuation of the handle 26 of the circuit breaker 14 towards the closed state.
  • the closed state of the auxiliary unit 10 corresponds to FIG. 4.
  • the movement of tripping of circuit breaker 14 following a fault detection is transmitted to the auxiliary unit 10 by the first mechanical link 16, pivoting the lever trigger 76 counterclockwise to unlock the attachment with the hook 72 of the mechanism 40 (Figure 7).
  • Joystick 54 is also driven by the tab 20 of the second mechanical connection 18 to a intermediate position (figure 8) corresponding to the triggered position of the lever 26 of the circuit breaker 14.
  • the opening spring rotates the plate 74 in the direction counterclockwise to bring it to a stop.
