Multi-pole circuit interrupter |
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.
