Definitions

  • the present invention relates to a differential switch connected in series to one or more protective elements such as fuse or circuit breaker circuit breakers, the switch and the aforementioned protective elements being housed in housings having two narrow faces opposite with input or output connection terminals, and two side walls opposite by which said boxes are joined two by two, the downstream connection terminals of the switch being electrically connected to the upstream connection terminals of the protection.
  • protective elements such as fuse or circuit breaker circuit breakers
  • the power supply of the switch and of the protective elements of the kind previously mentioned is carried out in a known manner. from above or below depending on the country of use, via cables. And, when all of these are arranged on a same rail, the connection of the switch output terminals to the input terminals of the protective elements, require a delicate passage of the cables from the bottom to the top (or inversely from the top to the bottom, in the case of feeding from the bottom), which results in a large overall size and not very easy to assemble.
  • Document FR-A-2 375 740 describes an electrical protection system comprising a differential device fitted in series with several protection devices.
  • the housing of the differential device comprises on one of its lateral faces, two input terminals and two output terminals, said terminals being located on the same side, relative to the rail, as the protection device input terminals. So in this document. the downstream connection of the differential device can only be carried out on one side of the rail.
  • the present invention solves these problems and proposes a differential switch associated with a or several protective elements, of reduced size and facilitating the work of the fitter.
  • the downstream connection of the switch can be made on either side of the rail.
  • the present invention relates to a switch according to claim 1.
  • the output terminals of the switch and the protective element input terminals are located on the supply side of the switch.
  • the switch housing has the same number of terminals of outlet on its two opposite sides, so as to allow connection to the comb of a either side of the boxes.
  • the housing of the switch further comprises a same number of input terminals on its two opposite narrow faces.
  • the aforementioned protective elements comprise at least a fuse circuit breaker and / or at least one circuit breaker.
  • the switch and the protective elements are of the type unipolar and neutral.
  • Figure 1 illustrates in a schematic view, a unipolar differential switch and neutral associated with two single-pole and neutral circuit breakers, in accordance with one embodiment particular 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 type generally used for the protection of several electrical circuits, associated with two single-pole circuit breakers and neutral 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 connection terminals are located, and two side faces opposite 1c, 1d; 2c, 2d; 3c, 3d by which the different elements are coupled.
  • the two circuit breakers D, E have two connection terminals for phase input and neutral 4.5 and 6.7 located on their upper narrow face 2a, 3a and two connection terminals 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 has two input terminals 12, 13 respectively for phase and neutral and two output terminals 14, 15 also of phase and neutral, and these two terminals of outputs 14 and 15 are separated by a distance (a) corresponding to the distance between the input terminals 4, 5 and 6, 7 of circuit breakers D, E, which terminals are located on the narrow upper faces 2a, 3a of the boxes 2, 3.
  • the assembly is placed on a DIN rail (not shown).
  • 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 produced by via a standard unipolar and neutral connection comb P connected to the output terminals 14, 15 of switch I and input terminals 4 to 7 of circuit breakers E, D.
  • the output terminals 8 to 11 of the circuit breakers E, D are connected to the corresponding terminals electrical equipment located downstream (not shown), and the input terminals 12, 13 of switch I are connected to power cables C.
  • the differential switch I has four connection terminals 12 to 15 on its upper narrow face 1a and 4 connection terminals 12a to 15a on its lower narrow face 1b, so as to allow supply of said switch I and of circuit breakers E, D, optionally from the top or from the bottom.
  • This embodiment of a double-bound switch allows quick connection by modular cabinet.
  • the differential switch I has two input terminals 12, 13 and two output terminals 14, 15 on the upper face narrow 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 combination with a differential switch, such as for example fuse holders or other.
