摘要： A decreased mechanical trip time latching system for use in a molded case circuit breaker assembly. The latching system comprising a quick release primary latch having a first primary latching surface and a second primary latching surface. Where the second primary latching surface engages a first secondary latching surface located on an interactive secondary latch, to prevent the rotation of the quick release primary latch. The first primary latching surface engages a cradle latching surface, located on a cradle, to prevent the rotation of the cradle. Assembled to the interactive secondary latch is a trip bar. Activation of the trip bar rotates the secondary latch so that the first secondary latching surface moves out of contact with the second primary latching surface just prior to the interactive secondary latch making physical contact with the quick release primary latch. The quick release primary latch then rotates moving the first primary latching surface out of contact with the cradle latching surface thereby releasing the cradle. The cradle rotates and the operating system is activated to terminate current flow.
