Definitions

  • the invention relates to a protective switching device according to the preamble of claim 1 (US 3,973,230).
  • a residual current circuit breaker is connected to one Protective switching device, for example in the form of Miniature circuit breaker, make sure that the circuit breaker cannot be switched on if the Residual current circuit breaker not switched on and therefore activated is. Allowed for many devices on the market a certain approximation of the contacts of the protective switching device, before being coupled to one Residual current circuit breaker in the off position by a unlatching Switch lock diverge again.
  • the invention has for its object a couplable To develop protective switching device in the case of a Residual current circuit breaker in the off position at an attempt to switch on the protective switching device the contacts are omitted.
  • the protective switching device should understandably with a connected residual current circuit breaker, which has tripped and been switched to the off position, prevent over the coupled circuit breaker reactivation is possible. When trying to restart the contacts do not approach each other.
  • His jack leads in a portable warehouse a movable contact arm, directly or indirectly.
  • the trigger lever is arranged in a fixed bearing and supports the movable contact arm in the open position of the Manual control unit.
  • a coupling rod is closed with the jack a swiveling hand control in another portable one Warehouse connected.
  • the spacer element around the bearing for the Coupling rod can be rotatably arranged on the pawl, the spacer element in the off position of the driver and in the off position of the protective switching device is against the release lever and prevents latching.
  • the driver can advantageously form an eccentric that Spacer deflects, this as a two-armed lever can be formed, one arm against the trigger lever can stand in line, and on his other arm in the off position of a residual current circuit breaker Driver acts deflecting.
  • the protective switching device 1 is designed to to an attachment, such as a residual current device, for example, behind the drawing level, to be lined up.
  • a driver 2 causes from a series-connected residual current circuit breaker Coupling.
  • the protective switching device 1 has one Latching point between a pawl 3 and a release lever 4 on.
  • the driver 2 moves in the off position a residual current circuit breaker directly or indirectly Distance between pawl 3 and release lever 4 giving distance element 5 such that the latching is prevented.
  • in the 1 acts on the driver 2 when rotating counterclockwise by about 70 ° directly on the distance-giving distance element 5 with one acting as an eccentric Cam 6 on.
  • the spacer element holds the release lever in the embodiment as far from the latch nose 7 from that a latch cannot take place.
  • the pawl 3 in a portable bearing 8th a movable contact arm 9, in the exemplary embodiment right away.
  • the trigger lever 4 is in a fixed position Bearing 10 arranged.
  • the axis 10 of the trigger lever 4 is supported the movable contact arm 9 in a partial recess 11 4 from the open position of the manual control element 13.
  • the Pawl 3 is pivotable via a coupling rod 12 Hand control 13 in another portable Bearing connected to the jack.
  • the driver 2 leads in the embodiment 1, a separate spacer element 5 regarding his movement.
  • the movable contact arm 9 and a fixed contact 15 form a contact pair, which in the practice has contact pieces 16.
  • the driver 2 is in the of a residual current circuit breaker caused off position, so when addressed has shown.
  • the protective switching device 1 in turn is also shown in the off position.
  • the driver 2 is in its rest position or at one Residual current circuit breaker not triggered.
  • the protective switching device is also in FIG Switched off position from the hand control 13 reproduced. 3 is for the rest position of the driver 2 or not triggered residual current circuit breaker the switch-on position the protective switching device 1 shown.
  • the spacer 5 is around the bearing 14 for the coupling rod 12 rotatably arranged on the pawl 3.
  • the spacer 5 prevents in the off position of the driver 2, according to FIG 1, and in the off position of the protective switching device the latch by moving it to the off position 5 against the trigger lever in the embodiment of FIG 4 is pending.
  • the driver 2 is in accordance with Figures 1 to 3 outside, above the geometric Locations of coupling rod 12 and pawl bearing 8, 14 arranged. Above is to be understood in relation to the fact that a Contact piece 16 on the moving contact 9 is regarded as being below this becomes. Due to the arrangement outside the geometric Places gain compatibility with different series of devices.
  • the driver 2 can form an eccentric, the on the spacer 5 in training as two arms Lever pending.
  • One arm 17 of the spacer element 5 stands against the release lever 4 at a distance.
  • against the other arm 18 of the spacer 5 is in the Switch-off position of a residual current circuit breaker of the drivers 2 with its cam 6 or with its eccentric profile distracting.
  • the portable bearing 8 of the jack 3 is on the fixed bearing 10 of the release lever 4 by a coupling means 19 connected, the bow-shaped in the embodiment is executed.
