Abstract (en)
A mechanism, for an enclosed residual current-operated circuit breaker, has a relay provided with a piston adapted to act on a tripping mechanism, a handle for resetting the tripping mechanism and for acting on the piston of the relay in order to return it to the normal operating condition, a preadjusted elastic member arranged between the handle and the piston so that the force applied to the piston is set by means of the elastic member and does not depend on the force applied to the handle. <IMAGE>
