A circuit breaker includes a housing and an operating mechanism having a cross
bar supported by a first housing surface and moving in an arcuate path between
open/tripped and closed positions, a pivotally mounted cradle including a latch,
and pivotally mounted primary and secondary latches. The primary latch includes
a pivot, an opening and a free end. The cradle latch rests within the opening when
the contacts are not tripped open. The secondary latch includes a pivot and a surface.
The latches are between a second housing surface and the cross bar in a first position.
The cross bar is offset from the latches in a second position. The secondary latch
surface and pivot are between the second housing surface and the primary latch
pivot. The secondary latch surface engages the primary latch free end when the
contacts are not tripped open and maintain the cradle latch within the opening.
