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 the 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 for transmitting the movement of the mobile element to the retractable contact, wherein the mechanical coupling is rigid and moves in translation according to a translation plane parallel to the movement of the mobile element and it is coupled to said pivoting lever at a point offset with respect to the plane of translation.
