A cradle stop assembly is provided for a circuit breaker including an
operating mechanism. The operating mechanism includes a pivotable movable
contact arm and a cradle member which is movable between a latched
position corresponding to separable contacts of the circuit breaker being
closeable and an unlatched position corresponding to the separable
contacts being tripped open. The cradle stop assembly includes a first
member coupled to a portion of the operating mechanism, a second member
disposed opposite the first member, and a generally planar stop plate
extending between the first and second members. A first stop portion of
the stop plate resists movement of the cradle member beyond a first
predetermined position to avoid the cradle member undesirably interfering
with the pivotable movable contact arm. A second stop portion resists the
pivotable movable contact arm from undesirably pivoting beyond a second
predetermined position.
