ABSTRACT:
A molded case circuit breaker includes an operating handle yoke that contacts the cradle operator and drives the operating mechanism springs over-center when the circuit breaker operating handle is moved from its RESET to its ON position. The contact between the handle yoke and cradle operator accelerates the over-centering of the powerful operating mechanism springs.
