  • the two upstream terminals 26.30 are juxtaposed on the same narrow side face 31 of the housing 12, while the two downstream terminals 28.32 are arranged side by side on the other opposite face 33.
  • the phase circuit 20 (FIGS. 1 and 3) comprises a movable contact 34 electrically connected to the upstream terminal 26 by a bimetallic trip unit 36, and a fixed contact 38 connected to a coil 40 for exciting an electromagnetic trip device 42.

  • the neutral circuit 22 ( Figures 1 and 2) has a fixed contact 46, a movable contact 48 electrically connected by a braid 49 to terminal 30, and a second arc extinguishing chamber 50
  • the neutral circuit 22 is located to the left of the phase circuit 20 and does not have a thermomagnetic trip device.
  • the two movable contacts 34, 48 are actuated by a first mechanism 52 with manual control by a lever 53 and automatic by the thermal bimetal trip unit 36 and the electromagnetic trip unit 42 with coil 40.
  • the first mechanism 52 can be of the type described in the document FR-A-2.616.583.
  • the second compartment 18 ( Figures 1, 4 and 5) is located to the right of the first compartment 16, and contains a differential transformer 54 having a secondary winding 59 connected to a trigger relay 56 cooperating with a second mechanism 58 with handle 60 for resetting .
  • the second mechanism 58 is coupled with the first mechanism 52 by means of mechanical connections (not shown) authorizing a tripping action of the circuit breaker 10 when a differential tripping order is issued by the relay 56, and a continued action of resetting the second mechanism 58.
  • the second mechanism 58 may be of the type described in document FR-A-2,628,262.
  • the differential transformer 54 includes a magnetic toroid 62 carrying a primary phase winding 64, a primary neutral winding 66, and the secondary measurement winding 59.
  • a ground fault causes an imbalance between the primary currents flowing through the primary windings 64 , 66, and generates an induced voltage across the secondary winding 59 to energize the trigger relay 56.
  • the primary neutral winding 66 is inserted in series in the neutral circuit 22 by interruption of the connection between the fixed neutral contact 46, and the downstream terminal 32 of neutral ( Figure 1 and 2).
  • the two orifices 80, 82 of the connection conductors 72, 74 are separated from each other by a predetermined interval, being located on the same side, in particular on the left, of the differential transformer 54.
  • the two openings 76,78 offset from the other pair of connection conductors 68,70 associated with the primary phase winding 64 are arranged to the right of the differential transformer 54.
  • the primary phase winding 64 is inserted upstream of the phase circuit 20, that is to say in the portion located between the phase contacts 34, 38 and the upstream phase terminal 26.
  • the primary neutral winding 66 is inserted downstream of the neutral circuit 22, that is to say in the portion situated between the neutral contacts 46, 48 and the downstream neutral terminal 32.
  • connection conductor 70 passing through the lower orifice 78 is connected to the base of the bimetallic strip 36, and the other connection conductor 68 passing through the upper orifice 76 is connected to the contact pad of the upstream terminal 26 of the phase.
  • the four connecting conductors 68.70; 72, 74 have projecting tongues of conductive material, arranged in overhang and extending parallel to one another in a direction perpendicular to the median wall 14.
  • Each tab (FIGS. 5 and 6) is equipped with a positioning recess 84 into which the corresponding end of the primary phase or neutral winding 64,66 is inserted.
  • the two zones of interruption of the phase 20 and neutral 22 circuits for the electrical insertion of the primary windings 64, 66 take place at different locations, arranged on either side of the differential transformer 54, and especially in the vicinity of opposite faces 31.33 of the housing 12.
  • Such an arrangement facilitates the automation of the electrical welding operations of the ends of the primary windings 64, 66 in the recesses 84 of the tabs and, on the other hand, improves the dielectric strength of the circuit breaker 10.
  • the second mechanism 58 is equipped with a test device 86 (FIG. 6) housed in the second compartment 18, and having a push button 88 intended to be actuated by sliding between a raised position of rest and a depressed working position.

  • the protection switch 96 is formed by an elastic conductive blade 100 supported in the closed position on an end wire resistance 90 when the mechanism 58 is in the armed state.
  • the test switch 98 comprises a strand 102 of a conductive spring intended to cooperate in the depressed position of the push button 88, with a connecting conductor 104 electrically connected to the connecting conductor 72.
  • the resistor 90 is switched on when the two switches 96.98 are closed, that is to say in the armed state of the mechanism 58, and in the depressed working position of the push button 88. This results in a current d test in the resistor 90, which is detected by the differential transformer 54 which triggers the second mechanism 58.
  • the pivoting of the rotary plate 106 of the mechanism 58 causes the first protective switch 96 to open automatically, causing the interruption of the test current in the resistor 90, even if the push button 88 remains held in the depressed position.
  • test circuit 92 takes place in the second compartment 18, and that the taking of information from the test takes place downstream of the neutral and phase contacts.
  • the tab 94 for interconnecting the resistor 90 with the phase circuit 20 crosses the middle wall 14, and is located at the potential of the upper arcing horn 108 in connection with the fixed phase contact 38.
  • the other end of the test circuit 92 is formed by the connection conductor 104 connected to the connection conductor 72 in connection with the fixed neutral contact 46.
  • test circuit 92 downstream of the phase and neutral contacts is essential to guarantee reliable operation of the differential circuit breaker 10 during a test, in particular avoiding the transfer of the upstream phase potential downstream of the neutral circuit, or the transfer of the upstream neutral potential downstream of the phase circuit during actuation from the push button to the depressed position.
  • the two ends of the test circuit 92 instead of being connected downstream (FIG. 6), can be connected simultaneously upstream with the phase contacts 34,38 and neutral contacts 46,48.
