Abstract A circuit breaker having a movable upper blade with a free floating pivot end. The operating mechanism is solidly connected to the Upper blade. The contact force is generated by a contact spring which exerts an upward force on the lower blade. No other resilient force acts directly upon the upper blade. As the contacts separate, the force exerted on the upper blade is virtually eliminated, reducing substantially the resistance at the pivot end of the upper blade. The load terminal and pivot end of the upper blade provide a current path parallel to that of the load side flexible connector.
