Abstract
An operating mechanism for a circuit breaker is provided. The operating mechanism includes a holder assembly being positioned to receive a portion of an operating handle of the circuit breaker. The holder assembly is capable of movement between a first position and a second position wherein the first position corresponds to a closed position of the circuit breaker and the second position corresponds to an open position of the circuit breaker. The operating mechanism further includes a drive plate being movably mounted to a support structure of the operating mechanism. The drive plate is coupled to the holder assembly. The operating mechanism also includes an energy storage mechanism for assuming a plurality of states, each state having a prescribed amount of energy stored in the energy storage mechanism. When the energy stored in the energy storage mechanism is released it provides an urging force to the drive plate causing the holder assembly to travel in the range defined by the first position to the second position.
