摘要： A multi-pole circuit interrupter comprising an electrically insulating housing having two side walls and at least two partition walls defining therebetween a central compartment and at least two side compartments. A central pole unit is disposed within the central compartment and a side pole unit is disposed within each of two side compartments. Each of the units includes a stationary contact element, a movable contact arm, an arc extinguisher and terminals for the external connection. The distance between a center line passing through the centers of the stationary contact element, the movable contact arm and the arc extinguisher of each of the pole units is smaller than the distance between the center lines passing through the terminals of each pole unit, so that the thickness of the housing side wall can be increased without increasing the overall width dimension of the housing.

摘要： A circuit interrupter comprises a toggle link having an upper toggle link and a lower toggle link pivotally connected by a knee pin to each other, a movable contact arm having a movable contact element secured thereon and connected to the lower toggle link of the toggle link, and a toggle link stopper capable of contacting the upper toggle link for preventing the bouncing back of the movable contact arm during tripping of the movable contact arm. The toggle link stopper is provided with a first stop surface which is brought into engagement with the upper toggle link when the movable contact arm is being tripped open and a second stop surface which is brought into engagement with the upper toggle link at a position closer to the knee pin than to the first stop surface when the movable contact arm is bouncing back. Thus, the toggle link is engaged by two stop surfaces at two stages, enabling the preventing of the bouncing of the movable contact arm.

摘要： A circuit interrupter comprising a stationary contact assembly having a stationary contact element securely attached to a stationary conductor, and a movable contact assembly having a movable contact element secured on a movable contact arm and operable in response to an overcurrent between ON and OFF positions relative to the stationary contact assembly. An arc runner is attached to the stationary conductor by a single rivet and includes an elongated main body extending along the stationary conductor for expanding an electric arc generated between the movable and the stationary contact elements upon current interruption. The circuit interrupter further comprises a pair of tabs mounted to the arc runner for defining a pair of sloped engagement surfaces for receiving and positioning therebetween the stationary conductor when the stationary contact assembly is assembled.
