Claims

[Scope of utility model registration request]

(i) a fixed conductor having a fixed contact at one end; a first iron piece that is attached symmetrically to the width or longitudinal centerline of the fixed conductor and generates a magnetic flux due to the current flowing through the fixed conductor; a movable conductor having opposing movable contacts on the distal end side; and a movable conductor mounted at the distal end of the movable conductor opposite to the first iron piece and symmetrically with respect to the center line in the width or longitudinal direction of the movable conductor. A switching device for a circuit breaker, comprising a second iron piece that is attracted to the first iron piece.
