Abstract

A circuit-breaker device of the vacuum type, which includes a shell in which a vacuum has been made and in which a first electrode and a second cooperating electrode are arranged, arranged so that, when the electrodes are separated, an arc and limbs of actuating rod coupled to the respective electrodes for effecting the separation thereof, in which the line of action of the contact separation surface areas of the electrodes are subjected to bending and shearing forces, to facilitate the separation of contacts.
