Abstract
An electrical protection apparatus is formed by association of a circuit breaker electrically connected in series with an effector. Switching of the arc onto an electrode when tripping of the mechanism occurs following a fault causes shunting of the effector. The electrode is separated from the stationary contact by an insulating gap, which is dimensioned to enhance said switching of the arc onto the electrode at the beginning of the opening travel of the movable contact, and to guarantee the dielectric withstand in the closed state of the contacts of the circuit breaker, and in the open state of the effector.
