Definitions

  • the invention relates to a mechanism for a residual current circuit breaker combined with a line circuit breaker according to the preamble of claim 1.
  • a mechanism for a residual current release combined with a circuit breaker which has a manual control toggle separate from the circuit breaker, a trigger relay that can be reset by a mechanism part and an on the latching of the circuit breaker acting transmission member (DE-OS 31 07 687).
  • the reduction in the number of individual parts leads to quite complicated and complex components, which particularly includes the ratchet lever, since this corresponds to at least 3 other components and has a ratchet nose equipped with a steel ball.
  • the recordings of the double-curved coupling bracket which serves as a connecting link between the residual current release and the adjacent circuit breaker, must be carried out very carefully, otherwise there is a risk of jamming.
  • the invention is therefore based on the object of providing a mechanism for a residual current circuit breaker of the type described above combined with a circuit breaker with the aim of using as few and uncomplicated components as possible and with a minimum of latching points.
  • a particularly advantageous embodiment of the object according to claim 1 can be seen in the return plate, which is not only responsible for the resetting of the triggering device, but also carries a reset bracket, which is indirectly responsible for triggering the circuit breaker.
  • a spring against the pressure of which the return plate can be moved, plays a decisive role.
  • FIG. 1 An embodiment of the invention is shown in a drawing and is explained in more detail below.
  • the figure shows a residual current circuit breaker in side view, with the side wall removed.
  • the mechanism of the residual current circuit breaker is accommodated in a housing 1, the visible side wall 2 of which adjoins an adjacent circuit breaker (not shown).
  • a slot 3 which is provided for a transmission element from the residual current circuit breaker to the adjacent circuit breaker.
  • a triggering device 4 is provided for triggering the residual current circuit breaker, which converts the electrical energy into mechanical energy.
  • the release device has an actuating element 5, which acts on a release plate 6 in the event of a release.
  • This release plate is approximately L-shaped in cross section, its longer leg 7 corresponds to a release lever 13 and the shorter leg 8 is bent at the end such that a small piece of this leg runs parallel to the longer leg and thus a stop 9 for the actuator 5 forms.
  • the release plate In the middle of the longer leg, the release plate has an angled tab 10 with a bore, which allows the release plate to be plugged onto a shaft 11 fixed to the housing.
  • the trigger plate is under the action of a torsion spring 14.
  • a return plate 15 has a tubular part 16 at the end, which encloses an axis 17 fixed to the housing. In the middle area, the return plate has an angled tab 18 with a bore, which serves to receive a reset bracket 21. At the free end, the return plate is angled in such a way that, when the residual current circuit breaker is switched on, it is approximately perpendicular to the trip plate 6 below the pivot point. The movement of the return plate takes place against the action of a conical spring 20.
  • the reset bracket 21 is bent at its free end in a circle and encloses a cylindrical pin 22.
  • a switch-off bracket 25 for the adjacent circuit breaker and an intermediate member 26 are connected to this cylindrical pin.
  • the cylindrical pin slides in one on both sides Switching gate 24, which is formed on the one hand by the rear wall 2 and on the other hand by an intermediate plate 30 (not shown).
  • the movement of the cylindrical pin takes place when it is switched on against the action of a torsion spring 23, which at the same time carries the tripping current when the test button is pressed.
  • the intermediate link is connected via a bracket 28 to the switch lever 29 of the residual current circuit breaker.
  • a latching lever 27 is also connected to the intermediate member and forms the latching point with the release lever 13, which is under the action of a torsion spring 14.
  • the adjacent circuit breaker Since the residual current circuit breaker has no switch contacts, the adjacent circuit breaker must take over the switching of the contacts, i.e. both switches must be turned on.
  • the circuit breaker can also be used up to a four-pole version.
  • the simultaneous switching on and off of a multiple combination by hand takes place by means of mutually coupled switch levers. When switching off in the event of a fault, all miniature circuit breakers trip simultaneously, since the release levers of all miniature circuit breakers are in operative connection with one another.
  • the triggering device 4 is acted on in such a way that the actuating member 5 steps outward and the triggering plate 6 moves clockwise.
  • the end of the longer leg 7 thus acts on the release lever 13 of the residual current circuit breaker, with the result that the latching point between the latching lever 27 and the release lever 13 is removed.
  • the cylindrical pin 22 can thus slide in the switching link 24 in the direction of the release lever 13, whereby the switch-off bracket for the circuit breaker simultaneously removes the latching point in the adjacent circuit breaker and opens the switching contacts.
  • the reset bracket 21 is actuated with this process, so that the return plate 15 rotates the release plate 6 counterclockwise and thus resets the release device 4 via the actuator 5.
