Abstract
An energy storage mechanism for a circuit breaker motor operator is disclosed. The energy storage mechanism has a first elastic member; a first fixture having a plurality of slots therein, the first fixture positioned in the first elastic member; a second fixture having a plurality of members defining an aperture; a second elastic member engaged to the second fixture and positioned within the aperture; wherein the second fixture is engaged to the first fixture. A motor operator for a molded case circuit breaker is disclosed. The motor operator has an energy storage mechanism for assuming a plurality of states, each state having a prescribed amount of energy stored in the energy storage mechanism; a mechanical linkage system coupled to the energy storage mechanism and to the molded case circuit breaker; wherein the molded case circuit breaker is operative to assume a plurality of positions; wherein each position of the molded case circuit breaker is associated with a corresponding state of the energy storage mechanism; a motor drive assembly connected to the mechanical linkage system for driving the energy storage mechanism from a first state of the plurality of states to a second s…
