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.
