摘要:
A lever arm assembly is provided for a circuit breaker trip actuator reset assembly including a cradle assembly pivotably coupled to the circuit breaker pole shaft, a reset lever pivotably coupled to the circuit breaker housing, and a trip actuator including an actuating element, which moves the reset lever in response to a trip condition. The lever arm assembly includes at least one linking element including a first end pivotably coupled to the cradle assembly, a second end, a pivot, and a deflection assembly having a deflection member. When the cradle assembly moves from a first position toward a second position, it moves the linking element, thereby moving the deflection member into engagement with the reset lever. This pivots the reset lever to reset the trip actuator. After the trip actuator has been reset, the deflection assembly is deflectable to accommodate excess motion of the cradle assembly.
