Definitions

  • the present invention relates to a remote control circuit breaker, the moving contact assembly of which is kept on or off by means of a bistable electromagnetic device.
  • this type of circuit breaker uses a tilting mechanism which maintains a lever and a moving contact assembly in the on or off position, so that the force required to operate the lever is maximum at center of stroke of the lever due to the spring force of the rocking mechanism. Therefore, in the case where such a circuit breaker is controlled by means of a remote control electromagnet assembly, as the attraction thereof is inversely proportional to the square of the width of the main air gap, the maximum force needs to be applied to the center of the stroke of the joystick, requiring an increase in the power of the electromagnet assembly. Thus, the circuit breaker leaves something to be desired in that the electromagnet assembly is large in size or that the excitation current of the windings is increased.
  • circuit breakers contain two electromagnets to ensure the switching on or off of the circuit breaker, which makes them unsatisfactory in that they are inevitably large.
  • one of the objects of the invention is to provide a remote control circuit breaker which makes it possible to reduce the force applied to the remote control electromagnet assembly and to globally miniaturize the circuit breaker.
