Definitions

  • the present invention relates to a group of parts comprising a circuit breaker, a base for fixing the circuit breaker and an electrical connection auxiliary module for circuit breakers.
  • Document FR 2 796 768 discloses a group of parts according to the preamble of claim 1.
  • a support and electrical connection base is typically mechanically fixed to the electrical panel, for example to a vertical plate or to uprights/crosspieces seated in the inner space of the electrical panel, and moreover it is electrically connected inside the electrical panel to an electrical installation the circuit breaker is to be connected to and in particular, to an electrical circuit upstream of the circuit breaker, or line circuit, and an electrical circuit downstream of the circuit breaker, or loading circuit.
  • the base includes electrical connection terminals, for example in the form of terminals, suitable for cooperating with respective connection terminals of the circuit breaker for connecting the circuit breaker to the line circuit and to the loading circuit.
  • the connection terminals of the circuit breaker are for example made in the form of bars intended for being coupled into corresponding complementary terminals provided in the base.
  • the use of a support and electrical connection base inside an electrical panel allows making the removal of the circuit breaker from the electrical panel and optionally a subsequent re-installation especially easy and quick.
  • the removal of a circuit breaker becomes necessary for example if the circuit breaker installed in the panel must be replaced with a new one or when, as required by the safety regulations, the temporary removal of the circuit breaker and its separation therefrom are required for carrying out maintenance operations on the electrical system controlled by the circuit breaker.
  • auxiliary devices those ancillary devices capable of providing auxiliary functions to the circuit breaker, such as functions of various types such as for example signalling, motor, etc. not directly related to the main function of the circuit breaker, that is, that of electrically connecting/disconnecting the line circuit from the loading circuit.
  • the first technique envisages making the connections of the auxiliary devices using conductor bundles with an end portion connected to the auxiliary devices and an opposite end portion provided with an electrical connector intended for being coupled to a complementary connector provided in the electrical panel.
  • the bundle of conductors is left sufficiently loose so as not to make the removal/insertion operations between circuit breaker and base very complicated.
  • This technique exhibits the advantage of a relative simplicity of wiring of the auxiliary devices, however it exhibits the disadvantage of having to provide for a sufficiently loose cable bundle in the electrical panel.
  • a further disadvantage of this solution is given by the fact that the operation of removal of the circuit breaker from the panel implies two subsequent operations: the circuit breaker must first be disconnected from the base and then the connector dedicated to the auxiliary devices must be disconnected.
  • the arrangement of an auxiliary connector is provided behind the circuit breaker and integral therewith; a complementary connector is provided on the base.
  • the electrical wires of the auxiliary devices are made to pass from the front of the circuit breaker, winding them quite strictly around the side walls of the same to reach the back connector.
  • the object of the present invention is to solve the disadvantages mentioned with reference to the prior art.
  • FIG. 1 shows an axonometric view of a circuit breaker provided with an auxiliary connection module according to the present invention, in a configuration of insertion of the circuit breaker into the respective base;
  • FIG. 2 shows an axonometric view of the circuit breaker of figure 1 , in a configuration of extraction from the respective base;
  • FIG. 3 shows an axonometric view of the circuit breaker of figure 1 , in a configuration of removal from the respective base;
  • FIG. 4 shows a side view of the circuit breaker of figure 1 , from the side of arrow IV of figure 3 , wherein the auxiliary connection module is in a second operating configuration
  • FIG. 5 shows a side view of the circuit breaker of figure 1 , from the side of arrow V of figure 2 , wherein the auxiliary connection module is in a second operating configuration
  • FIG. 6-8 show schematic partly cutaway side views of the circuit breaker of figure 1 , respectively in a first configuration of circuit breaker enabled, and in a second and third configuration wherein the circuit breaker is cut off, that is, extracted but connected to the base.
  • reference numeral 4 globally denotes an electrical connection auxiliary module for circuit breakers 8, preferably moulded case circuit breakers, suitable for making electrical connections between auxiliary devices of the circuit breaker and a support and electrical connection base 12.
  • Base 12 can be used for mechanically fixing the moulded case circuit breaker 8 into the housing of an electrical panel and for securing the electrical connections of circuit breaker 8 to an electrical circuit upstream of base 12, or line circuit, and to an electrical circuit downstream of base 12, or loading circuit.
  • a moulded case circuit breaker 8 as opposed to a so-called "open-type" circuit breaker, exhibits a box shaped body 16 made of insulating material, which has a carrying function for the internal circuits and mechanisms of the circuit breaker.
  • moulded case circuit breakers are generally used in the fields of industrial automation and of the high-tech service industry for cutting off currents for example even having a value up to 1500 A.
  • the moulded case circuit breaker 8 for example is a magneto-thermal switch. More in detail, in the particular example described circuit breaker 8 is a quadripole magneto-thermal moulded case circuit breaker.
  • the box-shaped body 16 of circuit breaker 8 comprises a back face 18, directly opposite the associable base 12 and a front face 19, opposite the back face 18 and carrying a control lever 20.
  • circuit breaker 8 is provided with gripping handles 22, better seen in figures 4 and 5 , connectable to two opposite horizontal faces 24 of the box shaped body 16 of circuit breaker 8 and suitable for making the connecting/disconnecting operations between circuit breaker 8 and base 12 easy and comfortable.

  • the electrical connection between circuit breaker 8 and base 12 takes place following the complete insertion of circuit breaker 8 into the respective base 12 ( figures 1 and 6 ).
  • circuit breaker 8 As is well known to an expert of the field, the main function of circuit breaker 8 is to selectively enable/cut off the electrical connection between the line circuit and the loading one. Other functions not directly relating to such function are called auxiliary functions (signalling, remote control, etc.).
  • circuit breaker 8 comprises coupling means (not shown) suitable for selectively coupling circuit breaker 8 to the respective base 12 in an insertion position and in an extraction position of circuit breaker 8.

  • the connection terminals of base 66 are for example connected by wires that are external to the base, not shown in the figures, to power/control/signalling devices provided in the electrical panel.
  • base 66 is built in and directly wired to the base without the use of a second box shaped element 66 distinct from base 12.
  • terminal board 58 is slidingly arranged into the box shaped element 50 so as to selectively shift from a coupling position, wherein terminal board 58 mechanically and electrically connects onto the corresponding base 66 to a disconnected position wherein terminal board 58 is mechanically and electrically disconnected from base 66.
  • the box shaped element 50 comprises an actuating button 70, mechanically connected to terminal board 58, for example by a stiff bracket having a first end portion connected to button 70 and an opposite end portion connected to terminal board 58, so as to allow the pressure-wise connection of terminal board 58 onto the corresponding base 66.
  • the actuating button 70 is arranged on a front face 74 of the box shaped element 50 adjacent the front face 19 of the associable circuit breaker 8.
  • the shifting stroke of button 70 and thus of the respective terminal board 58 relative to the first box shaped element 50 is at least equal to a cut off stroke S of circuit breaker 8, so as to allow the electrical connection of terminal board 58 to base 66, when circuit breaker 8 is in the extraction position, that is, constrained to base 12 but arranged at a predetermined distance therefrom.
  • module 4 may comprise locking means actuable for preventing the relative sliding between the box shaped element 50 and terminal board 58.
  • locking means comprise a stopping element (not shown), for example a block, suitable for being removably inserted in a recess defined between the first box shaped element 50 and the actuating button 70, so as to make button 70 integral with the first box shaped element 50.
  • the stopping element block any axial shifting movement of button 70 and therefore of terminal board 58 relative to the box shaped body 16 of circuit breaker 8.
