摘要
Linkage structure is connected between an operating mechanism and an actuating assembly of a circuit breaker for opening and closing an electrical contact of a pole assembly. The linkage assembly includes a lever to connect with the actuating assembly. A connection rod is coupled to one end of the lever and is associated with a close spring for closing the electrical contact. A spring structure is coupled to another end of the lever. The spring structure includes an open spring providing a spring force on the lever for opening the electrical contact. The open spring places the connection rod in tension. Retaining structure is associated with the lever and the spring structure to ensure that the spring force of the open spring, exerted on the lever, is directed to the retaining structure so that tension on the connection rod is removed, enabling the connection rod to be serviced.
