Circuit breaker including current path geometry to improve contact jump level

The invention relates to a circuit break including current path geometry to improve contact runout level. A circuit breaker (2) includes a housing (4), and a movable contact arm (12) arranged in the housing (4). The movable contact arm (12) includes a movable contact (14). The stationary contact assembly (8) is arranged in the housing (4). The stationary contact assembly (8) includes a base member (20) including a first side (24) and an opposite second side (25). An anti-bounce groove (28) having a wall portion (30) is formed in one of the first and second sides (24 and 25) and defines a cantilevered portion (32). The stationary contact member (46) extends from the first side (24) toward the second side (25). 本申请涉及包括提高触点跳动水平的电流通路几何形状的电路断路。电路断路器(2)包括壳体(4)，以及布置在壳体(4)中的可动触点臂(12)。可动触点臂(12)包括可动触点(14)。静触点组件(8)布置在壳体(4)中。静触点组件(8)包括底座部件(20)，其包括第一侧(24)和相反的第二侧(25)。具有壁部分(30)的抗跳动凹槽(28)形成在第一和第二侧(24和25)中的一者中，且限定悬臂部分(32)。静触点部件(46)从第一侧(24)朝第二侧(25)延伸。
