摘要： A variable drive coupling link assembly is utilized to drivingly couple a rotary motor operator mechanism to a circuit breaker mechanism operator member such as to provide a coasting zone intermediate the end of an operating member charging stroke and the start of an operating member return stroke during which the motor operator mechanism may coast to a stop. The link assembly is structured to abruptly shorten its effective driving length at the conclusion of a charging stroke and to re-establish its full effective driving length by the conclusion of the return stroke, thereby rendering the charging and return strokes of the operator member equal in length.

摘要： Apparatus drivingly couples a rotary motor operator mechanism to a reciprocating circuit breaker operator member such as to provide a braking zone intermediate the end of an operating member charging stroke and the start of an operating member return stroke during which the deactivated motor operator mechanism is brought to a stop without disturbing the operator member in its home position. Apparatus includes a latch for latching the operator member in its home position during the braking zone and a link assembly constructed to accommodate shortening of its effective drive length while a spring absorbs the kinetic energy of the motor operator mechanism. By the conclusion of the braking zone, the operator member is unlatched from its home position, and the spring discharges to propel the operator member to its return stroke while re-establishing the full effective driving length of the link assembly, thereby rendering the operator member charging and return stroke lengths equal.

摘要： A handle operator slide and a motor operator slide are individually coupled with a charging mechanism to independently charge charging springs thereof. The charging mechanism is operative to charge the springs of a contact operating mechanism as the charging springs discharge. The charging mechanism includes a prop controlled by the condition of the operating mechanism to releasably sustain the charging springs in a fully charged condition, while the operating mechanism includes a hook to releasably sustain the breaker contacts open against the urgence of fully charged operating mechanism springs. Consequently, the circuit breaker is capable of executing multiple contact opening and closing operations without recharging the charging springs by either the handle or the motor via their respective slides.
