CIRCUIT BREAKER LATCH MECHANISM INTEGRATED INTO THE ROTOR ASSEMBLY

A circuit breaker includes an electrically insulative case and a rotor assembly disposed within the electrically insulative case. The rotor assembly includes a contact arm and a rotor that is rotatable relative to the electrically insulative case. The contact arm is coupled to the rotor and movable between a first position in which a conductive path is closed and a second position in which the conductive path is open. The rotor assembly also includes a latch mechanism coupled to the rotor. The latch mechanism retains the contact arm in the second position during a short circuit event. The latch mechanism is spaced from the contact arm when the contact arm is in the first position. The latch mechanism engages the contact arm when the contact arm is in the second position. 断路器包括电隔离外壳和配置在该电隔离外壳内的转子组件。转子组件包括接触臂和转子，转子能够相对于该电隔离外壳旋转。接触臂联接于转子，且能够在第位置和第二位置之间移动，在第位置中，传导路径闭合，且在第二位置中，该传导路径断开。转子组件还包括联接于转子的闩锁机构。在短路事件期间，闩锁机构将接触臂固持在第二位置中。当接触臂处于第位置时，闩锁机构与接触臂间隔。当接触臂处于第二位置时，闩锁机构接合接触臂。
