摘要

Circuit breaker for limit current, high interrupting capacity, which includes a pair of terminals and the means comprising a mobile contact and a twin contact that provides a current passage that interconnects said terminals, and a mechanism to operate the contact mobile to open and close the circuit breaker, such device being characterized in that said current step includes a discharge opening loop that instantaneously drives the movement of one of the contacts by electrodynamic action in response to high and sudden current levels, and further characterized in that said mechanism for operating said movable contacts includes means for gradually operating the movable contact in the direction of contact closure, followed by a short and sudden contact closing movement, to quickly and firmly close the contacts. With a minimum of rebound, mechanical, avoiding this interference with the opening current impact of the discharge loop. (Machine-translation by Google Translate, not legally binding)
