  • the driving lever 58 is pivotally mounted on an axis 60 integral with the plates 44, 46, and is equipped, opposite the axis 60, with a cleat 62 for driving intended to come into engagement with the lever 24 to ensure closing the contacts 38, 40, 16 of the circuit breaker 12.
  • the mechanism 42 further comprises a reset cam 64 mounted on a transverse transmission shaft 66 extending perpendicularly to the plates 44, 46 and to the driving lever 58.
  • the cam resetting 64 cooperates with a roller 68 mounted for free rotation on the driving lever 58.
  • the profile of the cam 64 has a first sector 70 for arming the closing spring, and a second sector 72 for releasing the roller 68 allowing movement of abrupt pivoting of the driving lever 58 clockwise under the expansion action of the closing spring 50.
  • the second mechanism 42 is interposed between a geared motor member 74, and a manual emergency control 76 (FIG. 3).
  • the reset cam 64 is provided with a third bearing surface 104 arranged between the first sector 70 and the second sector 72 for the stable maintenance of the roller 68 in the armed position of the second remote control mechanism 42.
  • the second mechanism 42 is equipped with a first control button 94 for closing and a second control button 106 for opening, the latter cooperating with a push button 108 for triggering the attachment 36 of the first mechanism 20.
  • the push button 108 is interposed between the half-moon of the attachment 36 and the lower end of the push button 106.
  • crank pin 24 of the circuit breaker is engaged in a drawer 110 mounted in free translation in rectilinear slides 112 of the two plates 44, 46.
  • the drawer 110 is moved by the cleat 62 of the driving lever 58 between the open and closed positions of the pin 24.
  • the remote control unit 11 is pivotally mounted on a transverse axis 120 of a sole 122, which is fixed to the front face of the circuit breaker 12 after removal of the faceplate.
  • the sole 122 has a central opening 124 for the passage of the lever. 24, and lateral openings 126 for accessing the compartments for housing the auxiliary blocks of the circuit breaker 12.
  • the spacing between the two parallel plates 44, 46 of the second mechanism 42 of the tilting remote control unit 11 corresponds to that of the pair of fixed plates 128, 130 of the first mechanism 20.
  • the two plates 44 and 128 on the left are coplanar, as are the two plates 46 and 130 on the right (the latter not being shown in the figures).
  • a first anchoring element 132 intended to cooperate with a second anchoring element 134 conjugate provided at the upper part of each plate 128, 130 of the first mechanism 20 (figure 4).
  • the first anchoring element 132 is formed by a female part, for example a notch which engages at the end of tilting stroke of the remote control unit 11 on a male part, in particular a projecting tooth of the second anchoring element 134 ( figure 5). It is clear that the male and female parts of the anchoring elements 132, 134 can be reversed on the corresponding plates.
  • the tooth of the second anchoring element 134 projects from the front face of the circuit breaker.
  • the engagement of the anchoring elements 132, 134 makes it possible to adjust the remote control unit 11 on the circuit breaker 12 according to the manufacturing tolerances of the parts of the two mechanisms 20, 42. This results in precise positioning and centering of the second mechanism 42 on the first mechanism 20, as well as an improvement in the chain of mounting dimensions.
  • the tilting of the remote control unit 11 from the mounted position ( Figure 5) to the separated position ( Figure 4) allows direct access to the connection terminal block 127 as well as to the various compartments of the circuit breaker auxiliaries 12 through the openings 126 of the sole 122.
  • This accessibility facilitates the interchangeability of the auxiliaries, comprising in particular a block of contacts signaling CAOF of the position of the contacts, a block of signal fault SD, and auxiliary trip units with undervoltage MN, with current emission MX.
  • the second mechanism 42 is designed in such a way that the adaptation of the remote control unit 11 rocking on the circuit breaker 12 is only possible if the lever 24 and the second mechanism 42 are in agreement of states.

  • the indicator 138 comprises a polarization lever 140 articulated on an axis 142, and having at one of the ends an oblong groove 144, in which is engaged the axis of the roller 68 integral with the driving lever 58.
  • the other end of the coding lever 140 is arranged in locking spout 146 capable of interfering with the top of the lever 24 for prohibit the installation of the remote control unit 11 in the event of a discrepancy between the lever 24, the drawer 110 and the lever 140 of the indicator 138.
  • FIGS. 6 to 8 represent views illustrating different cases which may arise during the adaptation of the remote control unit 11 on the circuit breaker 12.
  • the handle 24 of the circuit breaker 12 is in the right position corresponding to the open state of the contacts 16, 38, 40.
  • the position of the polarizing lever 140 reflects that of the driving lever 58, and indicates l disarmed state of the energy storage system 48, in which the spring 50 is relaxed.
  • the blocking spout 146 abuts against the lever 24 before the end of the tilting stroke, and thereby prevents the adaptation of the remote control unit 11.
  • the lever 24 is in the left position, corresponding to the closed state of the contacts 16, 38, 40.
  • the energy storage system 48 of the second mechanism 42 is armed following compression of the closing spring 50.
