Abstract: A mobile pole of a switchgear that includes a pole cage comprising two parallel lateral walls, at least one of which delimits at least one centering hole defining a centering axis and an interior volume; a support leg, the pole cage being constrained to rotate with the support leg; and two flanges, each being configured to be connected to a respective lateral wall of the pole cage and including fixing members being configured to cooperate with the at least one centering hole, at least one of the fixing members being a load take-up device including a fixing part defining an insertion axis and a centering part adapted to cooperate with the fixing part and being configured to be inserted at least partly into the interior volume of the at least one centering hole with which said at least one of the fixing members is configured to cooperate so that the insertion axis of the centering part is aligned with the centering axis of the centering hole with which said at least one of the fixing members is configured to co

Abstract: This electrical circuit breaker includes at least one first fixed land, a support assembly equipped with at least one second land rotationally mobile, about a main axis, between a first position in which the second land is in contact with the first land and a second position in which the second land is separated from the first land and an arc-extinguishing chamber including a stacking of plates, a top arc-guiding horn, a bottom arc-guiding horn, equipped with at least one tab and a screen made of insulating material surrounding the bottom arc-guiding horn. The circuit breaker also includes two protuberances produced in a gas-producing material, which are mounted on the screen, arranged between the bottom horn and the top arc-guiding horn and facing the tab of the bottom arc-guiding horn, the protuberances having a prismatic or pseudo-prismatic form.

Abstract: A mobile pole is provided, including a pole cage including two walls, one of the two walls delimiting at least one centering hole defining a centering axis and an interior volume, a support leg, and two flanges, each flange being configured to be connected to a wall and including fixing members, each fixing member being configured to cooperate with the at least one centering hole, said each fixing member being a load take-up device including a fixing part defining an insertion axis and a centering part configured to cooperate with the fixing part, the centering part being configured to be inserted in the interior volume so that the insertion axis is aligned with the centering axis.

Abstract: An electric power circuit breaker with an energy storage device and an indicating device including an indicator lever with an indicator and an indicating cam of loaded and unloaded states of the loading mechanism. The indicating cam is mounted on the loading shaft in proximity to the loading cam, and includes a notch for receipt of the indicator lever when the mechanism is in the loaded state. The indicating cam includes a single ramp for progressively bringing the indicator lever into position up to the notch to guarantee latching of the opening latch maintained in a tripped position by the auxiliary release.
