Definitions

  • the present invention relates to a differential switch connected in series with one or more protective elements such as fuse or circuit breaker circuit breakers, the aforementioned switch and protective elements being housed in housings having two opposite narrow faces comprising terminals input or output connection, and two opposite side walls by which said boxes are joined in pairs, the connection terminals downstream of the switch being electrically connected to the connection terminals upstream of the protective elements.
  • the supply of the switch and of the protection elements of the aforementioned kind takes place in a known manner, from above or from below depending on the country of use, by means of cables. And, when all these elements are arranged on the same rail, the connection of the output terminals of the switch to the input terminals of the protective elements, require a delicate passage of the cables from the bottom to the top (or vice versa from the top to the bottom, in the event of feeding from the bottom), which results in a significant bulk of the assembly and an uneasy assembly.
  • the present invention solves these problems and proposes a differential switch associated with one or more protective elements, of reduced bulk and facilitating the work of the fitter.
  • the present invention relates to a differential switch intended to be connected in series to one or more protective elements such as fuse-circuit breakers or circuit breakers, the above-mentioned switch and protective elements being housed in housings having two opposite narrow faces comprising input or output connection terminals, and two opposite side walls by which said housings are joined in pairs, the output terminals of the switch being electrically connected to the input terminals of the elements of protection, this switch being characterized in that the output terminals of the switch and the input terminals of the protective elements are located on the same side of the housings, the aforementioned output terminals being separated two by two from one predetermined distance corresponding to the spacing of the input terminals of the protective elements, so enable the connection of said terminals to a connecting comb located on the supply side of the protection elements.
  • the output terminals of the switch and the input terminals of the protective elements are located on the supply side of the switch.
  • the switch housing has the same number of output terminals on its two opposite faces, so as to allow connection to the comb on one side or the other of the housings.
  • the switch housing also has the same number of input terminals on its two opposite narrow faces.
  • the aforementioned protection elements comprise at least one fuse-circuit breaker and / or at least one circuit breaker.
  • the switch and the protection elements are of the unipolar and neutral type.
  • FIG. 1 illustrates in a schematic view, a unipolar and neutral differential switch associated with two unipolar and neutral circuit breakers, in accordance with a particular embodiment of the invention.
  • FIGS 2, 3 and 4 respectively illustrate, also in schematic views, three other embodiments of the differential switch of the invention.
  • FIG 1 we see a unipolar and neutral switch I of the kind generally used for the protection of several electrical circuits, associated with two unipolar and neutral circuit breakers D, E.
  • This switch I and its associated circuit breakers D, E are each housed in a housing 1, 2, 3 of parallelepiped shape having two opposite narrow faces 1a, 1b; 2a, 2b; 3a, 3b on which are located connection terminals, and two opposite side faces 1c, 1d; 2c, 2d; 3c, 3d by which the different elements are coupled.
  • the two circuit breakers D, E comprise two terminals for connection of phase and neutral input 4.5 and 6.7 located on their upper narrow face 2a, 3a and two terminals for connection of phase and neutral output 8 , 9 and 10, 11 located on their lower narrow face 2b, 3b.
  • the upper face 1a of the housing 1 of the switch I comprises two input terminals 12, 13 respectively of phase and neutral and two output terminals 14, 15 also of phase and neutral, and these two output terminals 14 and 15 are separated by a distance ( a) corresponding to the distance separating the input terminals 4, 5 and 6, 7 of the circuit breakers D, E, which terminals are located on the narrow upper faces 2a, 3a of the boxes 2, 3.
  • the electrical connection between the output terminals 14, 15 of the switch I and the input terminals 4, 5 and 6, 7 of the circuit breakers E, D is made by means of a comb P of unipolar and neutral connection standard connected to the output terminals 14, 15 of the switch I and the input terminals 4 to 7 of the circuit breakers E, D.
  • the output terminals 8 to 11 of the circuit breakers E, D are connected to the corresponding terminals of the electrical equipment located downstream (not shown), and the input terminals 12, 13 of the switch I are connected to power cables C.
  • the differential switch I comprises four connection terminals 12 to 15 on its upper narrow face 1a and four connection terminals 12a to 15a on its lower narrow face 1b, so to allow a supply of said switch I and of circuit breakers E, D, either from the top or from the bottom.
  • This embodiment of a double-bound switch allows quick connection in a modular box.
  • the differential switch I comprises two input terminals 12, 13 and two output terminals 14, 15 on the narrow upper face 1a of the housing 1, as well as two output terminals 14a, 15a on the narrow underside 1b of said housing 1.
  • the connection of the comb P and therefore the supply of the circuit breakers E, D can be made either from above or from below.
  • circuit breakers could have been used in association with a differential switch, such as for example fuse holders or the like.
  • a differential switch has therefore been produced associated with circuit protection elements allowing the use of standard existing combs without the aid other connections which are difficult to wire, which reduces the overall dimensions of the assembly and facilitates the work of the fitter.
