ABSTRACT:
A manual opening device is for an electrical switching apparatus, such as a synchronous circuit breaker, including a housing having an opening, a plurality of pole mechanisms each comprising separable contacts, and at least one operating mechanism including a number of actuators adapted to open and close the separable contacts. The operating mechanism is supported by the housing and includes a corresponding pole shaft. The manual opening device comprises an operating handle, a cam assembly, and a drive assembly. A first end of the operating handle protrudes through the opening of the housing and the second end is coupled to the cam assembly. The drive assembly couples the cam assembly to the corresponding pole shaft of the operating mechanism and cooperates with the corresponding pole shaft and actuators to simultaneously open the separable contacts when the operating handle is moved from a first position to a second position.
