Abstract
A circuit breaker is provided with at least one switching arrangement having a mobile contact and a retractable contact, this latter being supported by a pivoting lever; a tripping mechanism for causing rapid opening of the mobile contact, an electromagnetic actuator having an element movable in translation under the effect of a control signal applied to the actuator and a mechanical coupling element for transmitting the movement of the mobile element to the retractable contact, wherein the mechanical coupling element, rigid and movable in translation parallel to the axis of displacement of the mobile element, is coupled to one end of the pivoting lever and, at its opposite contact end, the pivoting lever has an arm bent so that an end portion of substantial length of the arm is substantially parallel to the opposite arm of the corresponding mobile contact lever, the pivoting axis of the pivoting lever being placed between its bend and the coupling end.
