摘要： An apparatus for electrically operating a circuit breaker comprising a trip display mechanism for displaying trip condition of the circuit breaker while the circuit breaker is in trip state thereof. The trip display mechanism comprises an elongate trip detecting plate which is supported pivotally at intermediate point thereof on a slider and engages at its one tip end with the handle of the circuit breaker which causes the trip detecting plate to pivot during the trip condition; and an elongate trip display plate having an indicia indicative of the trip condition of the circuit breaker at one end thereof, the display plate being swingably supported at intermediate point thereof on a frame and engaging with the other end of the trip detecting plate, the trip display plate being caused by the trip detecting plate to swing to a position where the indicia appears on a display window during the trip condition of the circuit breaker.

摘要： An apparatus for electrically operating a circuit breaker comprising an electrically powered pawl which is driven by an electric motor for causing a ratchet to rotate and a release mechanism for causing the electrically powered pawl to move out of driven engagement with the ratchet when the ratchet rotates to a predetermined angle. A guide bar on which a spring is mounted is secured on a main frame. A slider is slidably provided on the guide bar. The slider engages with a handle of the circuit breaker and throws the circuit breaker when it slides on the guide bar. The slider is driven into sliding motion by a cam which rotates with the ratchet gear in a unitary motion and the slider compresses the spring on the guide bar. When the slider reaches up a position where the circuit breaker is turned off, the release mechanism causes the electrically powered pawl to move out of driven engagement with the ratchet.
