Definitions

  • the invention relates to the field of line and residual current circuit breakers, in particular those of the combined line and residual current circuit breakers (called residual current breaker with overcurrent protection, RCBO).
  • It relates to a combined circuit breaker with a residual current device for a low voltage installation with at least a first current phase (L1).
  • Combined line and residual current circuit breakers serve to protect an electrical load from overcurrent and at the same time to switch off if a fault current occurs.
  • the latter function is known as a so-called F / I circuit breaker.
  • the combined device can be applied, for example, to a hat rail profile or plugged into a socket.
  • both the residual current circuit breaker and the at least one circuit breaker are housed in a common housing. This requires that all components of the combined line and residual current circuit breaker are typically assembled at a mounting location. It has been found that such combined switches in the direction of a longitudinal axis normally require a relatively large amount of space. In addition, different sized housing needed when single-pole or multi-pole combination devices to be realized.
  • the circuit breaker and the residual current circuit breaker are each self-contained devices that are electrically wired together to a combination device.
  • the implementation of single-pole or multi-pole combination devices is thereby made easier than with combi devices of the first type, because each phase - ie each pole - is associated with a residual current protection module.
  • combi tools of the second type also show that they usually require a relatively large amount of space in the direction of a longitudinal axis. For example, it can be stated that, given a predetermined module width of the line protection module extending in the direction of the longitudinal axis a module width of known residual current circuit breaker is typically typically twice as large as a module width of a single line protection module.
  • the module widths usually go hand in hand with the requirements regarding predefined mounting locations (eg slots) for the mechanical fastening of the combined line and residual current circuit breaker or its components.
  • the at least one circuit breaker and the residual current circuit breaker must be electrically connected to each other by means arranged outside the housing connecting lines, so that the combination device is functional and easy to use.
  • the residual current protection module is constructed and designed such that a module width of the residual current protection module is at most moderately the same size as a module width of the at least one functional line protection module.
  • the residual current protection module for a low voltage installation having at least a first current phase (eg L1) has a first housing part, a first pole assignable to a neutral, and one with the first one Pol connected summation current transformer.
  • the first pole can be electrically connected to the neutral conductor via a consumer.
  • the first pole can be connected via a test resistor to the second pole of a protective device, that is to say a circuit breaker, in order to be able to achieve an F / I tripping function.
  • a first opening is further arranged through which the summation current transformer with the outside of the residual current protection module arranged current phase (L1) is connectable.
  • one or more leading to the summation current transformer connecting lines may already be passed around the summation current transformer or wound around and protrude, for example, as a cable end of the first opening.
  • the residual current protection module may have one or more connection points, which are arranged immediately after the first opening of the residual current protection module, so that they are accessible from outside the residual current protection module.
  • the at least one connection leads from the connection point inside the device to the summation current transformer.
  • the connecting lines (s) coming from the line protection module are then connected to the connection point (s).
  • the connecting lines can be designed as a cable or as a molded part (such as a sheet metal part).
  • the residual current protection module can be installed in the installed state of the residual current protection module in the low-voltage installation to an adjacent protection device such that the first opening extends in the direction of the adjacent protection device.
  • the first opening forms an internal device interface for bringing the electrical potential of a current phase (for example L1, L2 or L3) of a first functional line protection module, which can be arranged directly next to the residual current protection module, to the summation current transformer in the residual current protection module.
  • a current phase for example L1, L2 or L3
  • the electric potential of the current phase is introduced through an opening in that housing to the above-mentioned first opening.
  • bipolar is meant, for example, a pole for a neutral conductor and a pole for a first current phase.
  • the residual current protection module preferably has a wall section, which is a side wall section of the first housing part. This wall section points in the installed state of the residual current protection module in the low-voltage installation to the adjacent protection device.
  • the adjacent protection device also referred to below as the first functional line protection module, is arranged directly next to the residual current protection module in the low-voltage installation.
  • this residual current protection module can only be used for introducing the electrical potential of the current phase to the summation current transformer in the residual current protection module, while the return from the summation current transformer takes place back to the current phase outside the housing of the residual current protection module.
  • the return is at least in an indentation of the housing can be arranged.
  • the first opening serves not only for introducing the electric potential of the current phase to the summation current transformer in the residual current protection module, but at the same time also for leading out the electrical potential of the current phase from the summation current transformer, then both electrical interfaces between the residual current protection module and the first functional line protection module in assembled state of Kombiellas of external accesses and manipulations protectable or protected.
  • the combined device can be installed directly in a low-voltage installation and requires only one connection to the first phase associated with the second Pol relays the second pair of poles of the first functional line protection module, and for example the neutral conductor at the first pole, or the first pole pair of the residual current protection module.
  • the residual current protection module allows to be used both for single-pole and multi-pole functional line protection modules without the need for modifications to the residual current protection module itself. It goes without saying that this is also extremely interesting from an economic point of view (participation et cetera).
  • a residual current protection module has a test or test button with which the reliable tripping function of the residual current protection module can be checked periodically.
  • the test button can be moved relative to the first housing part in an actuating direction and is raised relative to the first housing part in the unactuated state.
  • the term sublime means protrusion or protuberance from a contour of the housing. Raised test buttons are preferred over test buttons housed in the housing because they are easier to operate by the user.
  • a residual current protection module or a combi unit is placed something just below a cover, the cover can operate the test button unintentionally, which is disturbing for the operation of the low-voltage system.
  • the first housing part has at least one projection which extends in the actuating direction and which only partially surrounds the test button.
  • the test button for the user is still easy to use. Due to the fact that the at least one projection is at least as high as an end face of the test button, the test button is reliably protected against unintentional actuation from the front, that is, for example, reliably protected by the above-mentioned cover.
  • the at least one projection which extends in the direction of actuation is designed to be pin-shaped or U-shaped. In the latter case, the projection with a U-shaped cross section surrounds the test button in the circumferential direction relative to the actuating direction, for example approximately halfway.
  • such a combined device has a fault current protection module according to the invention as described above, as well as a first functional line protection module.
  • This first functional line protection module has a second housing part with a second opening arranged therein and a second pole that can be assigned to the first current phase (L1).
  • the second pole is electromagnetically connected to the summation current transformer via a first connecting line guided through the first opening and the second opening.
  • the first functional line protection module is mechanically an integral module independent of the residual current protection module
  • the residual current protection module can be manufactured and pre-tested independently of the first functional line protection module. This opens up new possibilities in the procurement strategy and the geographical production sites of the two modules.
  • a basic embodiment of a four-pole combined line and residual current circuit breaker has a second functional line protection module which has a third housing part with a third opening arranged therein and a third pole assignable to the second current phase (L2).
  • the third pole is electromagnetically connected to the summation current transformer via a second connecting line guided through the first opening.
  • a third functional line protection module is present, which has a fourth housing part with a fourth opening arranged therein and a fourth pole which can be assigned to the third current phase (L3).
  • the fourth pole is electromagnetically connected to the summation current transformer via a third connecting line which is passed through the first opening.
  • the advantage of such an embodiment is, for example, that the total module width has three times a module width of the functional line protection modules, and in addition a residual current protection module, for example, the same module width as a functional line protection module, so that the total module width corresponds to only four times the module width of a functional line protection module ,
  • the second connection line is preferably passed through the fourth opening, and the third connection line passed through the third opening and the fourth opening. In this way, at least the lead, depending on the embodiment, even the return of the connecting line to the summation current transformer during operation and during assembly against unauthorized access protected.
  • the first housing part has a first bottom, and a first cover, which surrounds the residual current protection module with the summation current transformer.
  • the term 'surround' is therefore understood in the sense of an at least partial physical envelope of the residual current protection module, ie, for example, a housing shell which terminates more than 50% of a surface of the envelope of the residual current protection module to the outside.
  • the respective housing half-shell In order to manufacture and prespecify all functional line protection modules independently of each other in the four-pole combined line and residual current circuit breaker, it may be useful to construct the respective housing half-shell, so that the second housing part comprises a second bottom and a second cover, the third housing part a third floor and a third cover, the fourth housing part comprises a fourth bottom and a fourth cover.
  • the half shells have the further advantage that they may also have holding and positioning means for holding and / or receiving parts of the functional line protection modules. The same applies mutatis mutandis to the bottom and cover of a properly executed residual current protection module.
  • the number of identical housing parts in the four-pole combined line and residual current circuit breaker is further optimized to a minimum, when the second lid, the third lid and the fourth lid are identical and when the third bottom and the fourth bottom are identical.

  • the fourth housing part can be used as the bottom of the third functional line protection module and as the cover of the second functional section Be designed line protection module.
  • the third housing part is designed on the one hand as the bottom of the second functional line protection module and on the other hand as a cover of the first functional line protection module. Further, the second housing part is configured as the bottom of the first functional line protection module.
  • An advantage of such an embodiment is that less space must be provided for line return inside the combi unit.
  • a further advantage is that the connecting lines leading back to the respective functional line protection module can still be mounted after the assembly of the RCBO, which can simplify the complexity of assembling the combined device somewhat.
