  • Apparatus for remotely actuating a manual actuator of a circuit breaker
    Patent number: 7532095
    Abstract: An apparatus for remotely actuating a circuit breaker with two stable positions corresponding to a switch-on position and a switch-off position, has a drive mechanism with an electric motor. The apparatus further has first and second switches for switching the motor on and off, a transmission, a coupling mechanism for mechanically coupling the drive mechanism to the circuit breaker and a lever. The transmission can be positioned in two basic positions, and the lever is capable of being moved from a first end position into a second end position with the aid of the drive mechanism. The drive mechanism is configured such that, in the event of the lever being moved over manually from one end position into the other end position, one of the switches is actuated, with the result that the transmission is moved over from one basic position into the other basic position.
