Circuit breaker trip latch assembly

Image Number 7 for United States Patent #4301346.

A circuit breaker trip latch assembly includes a primary latch having a latching member releasably latching a cradle in its reset position against the bias of charged operating mechanism springs. The primary latch and either one of the first and second secondary latches commonly engage a latch pin carried by the free end of a pivotally mounted, elongated intermediate latch. The geometry of this common engagement is such as to greatly reduce the force of the charged mechanism springs ultimately absorbed by the first secondary latch as the cradle is relatched and the second, trip initiating, secondary latch while the breaker is closed.
