Abstract
A device is provided comprising a simple means for holding the contacts apart and insulated from each other after circuit breaking. A screen formed by an insulating plate of small thickness, is placed between two mobile contact levers and is urged by springs against flanges which are integral with the levers and which move apart when short circuit currents appear for allowing this screen to be rapidly projected between the contact inserts. This simple circuit-breaker device may be used such as it is or in association with a contactor for protecting lines which supply consumer apparatus.
