Definitions

  • the reset mechanisms making a control cam and a roller of a driving lever cooperate are well known for ensuring the actuation of a closing spring in the direction of compression and expansion.
  • Such a device is illustrated in document EP-A-222,645, which forms the base of the preamble of claim 1, in which a special hooking stage maintains the cam of the mechanism in the armed state.
  • the attachment stage comprises for this purpose a closing pawl associated with a half-moon lock, which is controlled either manually by a push button, or electrically by excitation of an engagement electromagnet.
  • the presence of the pawl is essential, because of the antagonistic action of an imbalance torque on the cam, the torque resulting from the spring tension and the angle formed by the reaction of the roller on the cam, and the line passing through the roller and the axis of the cam.
  • the production of such a device is complicated, and increases the cost price of the mechanism.
  • the object of the invention is to improve the production of a remote control mechanism for a multipole circuit breaker.
  • the remote-controlled circuit breaker is characterized in that the resetting cam has a shaped support surface to stabilize the roller in the armed position of the driving lever thanks to the passage of the action line of the reaction R of the roller by the drive shaft of the reset cam, and that the geared motor member is provided with means for ensuring an almost instantaneous stop of the reset cam when the roller arrives in the vicinity of the bearing surface.
  • the opening of the circuit breaker, and the accumulation of energy in the closing spring is effected by means of the cam and roller assembly, the cam shaft being actuated electrically by the gear motor, or manually by the emergency command.
  • the sudden closing of the circuit breaker results from the crossing of a hard point of the roller on the cam, the latter being actuated electrically by the gear motor or manually by means of a closing push button.
  • the shape of the bearing surface of the cocking cam is flat or curved.
