  • the purpose of the circuit breaker control circuit is to detect current leaks exceeding a fairly low threshold value (less than 6 mA at 200 volts AC) between the phase conductor and the third local ground terminal. To this end, this control circuit is sensitive to the difference in potential existing between the local ground and the earth during the passage of said current and due to the fact that the resistance between these two points is not zero.

  • the cross section of the cocking lever 150 is advantageously complementary to the cross section of the bore 136 and the orifices 55 and 172.
  • this cross section is generally square. This provision should not however be considered as limiting.

  • the bearing surface 153 is generally curved, of convex shape, around an axis contained in the plane of symmetry OOAA and perpendicular to the axis OO of translation cocking lever 150.
  • This advantageous arrangement defines a point contact between the bearing surface 153 and the auxiliary branch 141 of the retaining spring 140 in piano wire. Such a characteristic avoids inadvertent catching of the retaining spring 140 on the arming lever 150, makes it possible to easily release the arming lever 150 when the auxiliary branch 141 of the retaining spring is moved by the pallet 190 against its residual elasticity, and thereby guarantees high sensitivity to the circuit breaker according to the present invention.
  • the elastic biasing means 160 are in this case formed by a helical spring interposed between the aforementioned plate 171 and secured to the electric coil support 170 and an annular rib 154 secured to the cocking lever at the control end 152 of it.
