Abstract
A manual opening assembly includes a manual actuator assembly. The manual actuator assembly includes a handle assembly and a number of operating levers. The handle assembly includes a handle member structured to be movably coupled to a circuit breaker housing assembly and to move between an operating position and an opening position. The handle member is operatively coupled to the number of operating levers. The number of operating levers are movably coupled to a circuit breaker housing assembly. The operating levers are structured to move between an operating position, wherein the operating levers do not operatively engage a linkage assembly, and an opening position, wherein the operating levers operatively engage the linkage assembly and move the linkage assembly from a closed, second configuration to an open, first configuration.
