Abstract
The circuit breaker is fitted with an electromagnetic actuator (AE), comprising a magnetic circuit (7) in the form of an `H'. The circuit includes a first air gap (17) in which a mobile contact arm (5) is suspended and a second air gap (19) associated with a pivoting paddle (8). A hammer (9) is connected to the paddle (8) to reinforce the opening action of the contact arm (5). The hammer (9) is formed by an extended piece situated between the magnetic circuit (9) and the first compartment (30). This cooperates with the support (26) of the contact arm to block the passage between the first and second compartments after attraction of the paddle, and to free the passage after the return of the paddle to its separated position. <IMAGE>
