Flux shifter reset assembly

A flux shifter reset assembly for reliably reseating the plunger of a flux shifter-type trip solenoid from its circuit breaker trip initiating extended position, said assembly comprising, in combination:

• A. an activating element mounted for movement with the breaker movable contact assemblies between first, second and third positions as the movable contact assemblies swing between closed, hooked open and tripped open positions, respectively;
• B. a reset lever mounted for pivotal movement between a de-actuated position and an actuating position, said reset lever including a projection disposed to engageably restore the trip solenoid plunger from its extended position to its reseated position as said reset lever is propelled from its de-actuated position to its actuated position;
• C. an elongated actuating arm pivotally mounted adjacent one end to said reset lever;
• and
• D. means resiliently driving coupling the other end of said actuating arm to said reset lever, with said reset lever in its de-actuated position, said actuating arm disposed to be engaged by said activating element as it moves from its first position toward its second position such as to rotate said reset lever and actuating arm as a unit about the reset arm pivotally mounting, said reset lever achieving its fully actuated position to reseat the trip solenoid plunger prior to the arrival of said activating element at its second position, with movement of said activating element on to its third position, said drive coupling means simultaneously yielding to accommodate overtravel pivotal movement of said actuating arm about its pivotal mounting with said reset lever and applying a resilient force holding said reset lever in its actuated position.
