Zusammenfassung: | An operating mechanism for manipulating an operating handle of a circuit breaker is provided. The operating mechanism includes a holder assembly being configured, dimensioned and positioned to receive a portion of the operating handle where 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 handle and the second position corresponds to an open position of the handle. 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 inthe range defined by the |
