ABSTRACT:
Two puffer type circuit breaking units are symmetrically disposed with respect to a bracket interposed therebetween. Linking means are mounted in the bracket, and one end of the linking means is connected to movable parts of the puffer type circuit breaking units and the other end is connected to operating means through an electrically insulated operating rod. An electromagnetic coil is disposed in the bracket and an electromagnetic repulsive member is electromagnetically connected to the electromagnetic coil to produce an electromagnetic repulsive force. During the breaking operation, current transferring means mounted in the puffer type breaking units are actuated to apply an electric current to the electromagnetic coil, and an electromagnetic repulsive force is imposed on the electromagnetic repulsive member to actuate the movable parts of the puffer type breaking units together with the operating means, whereby the breaking of a large current is made possible. Since the current transferring means are disposed in the breaking units, the structure of the current transferring means is simplified and construction thereof is facilitated and transfer of an electric current to the electromagnetic coil can be performed assuredly.
