Mechanical interlock for circuit breaker to prevent relatching of the breaker

Image Number 3 for United States Patent #8120452.

An apparatus and method for restricting auxiliary latch movement within a tripped circuit breaker. An auxiliary latch is held in a closed state and is biased into an open state. When the trip bar is activated in response to an overload condition, it releases the auxiliary latch which pivots to the open state. The cradle is released and pivots to disengage the breaker contact. Tabs on the cradle and auxiliary latch cooperatively interlock to limit auxiliary latch movement until the latch is properly reset.
