<p>Instantaneous trip for electrical apparatus for protecting lines of the circuit breaker type, comprising per line a pair of respectively fixed and moving contacts and two devices for connection to said line, a handle for controlling said contacts between a first separation position and a second contact position. This electrical apparatus is characterized in that the electrical link between the moving contact and the connection device linked thereto passes through a magnetic circuit in the form of a loop of plane shape furnished with a fixed yoke (2) and with a movable pallet (3) that can move against restoring means (10) recalling it to the open position, said pallet (3) actuating a trip (11) of the lock when it is attracted into contact with the fixed part (2) of the loop.</p> |
