    摘要: A circuit breaker including a housing, separable contacts, a cradle rotatably mounted within the housing, an alarm switch mounted within the housing, and an interface lever disposed between the cradle and the alarm switch. The cradle is adapted to rotate about a first axis in a first direction when the circuit breaker moves to a tripped position in which the separable contacts are separated from one another. The alarm switch includes an actuation lever movable in an actuation direction, wherein movement of the actuation lever in the actuation direction causes the alarm switch to activate an alarm device electrically connected thereto. When the cradle rotates in the first direction, the cradle exerts a first force against the interface lever that causes the interface lever to exert a second force against the actuation lever that causes the actuation lever to move in the actuation direction.

    摘要: The reset lever on a circuit breaker undervoltage relay is actuated by translating arcuate movement of a handle arm pin as the circuit breaker handle is moved to the off position into rotation of the reset lever through a complaint interface lever that is stiff enough to actuate the reset lever, but flexible enough to accommodate for overtravel of the handle arm pin when the circuit breaker is reset and for the stackup of tolerances in the operating mechanism.

    摘要: An interlock mechanism for preventing a first circuit breaker having a first actuating mechanism and a second circuit breaker having a second actuating mechanism from simultaneously being in a closed condition. The interlock mechanism includes a frame, a sliding bar slideably mounted within the frame, and one or more retaining protrusions extending outwardly from one or more inner edges of the frame. The sliding bar is movable between a first position and a second position. In the first position the sliding bar blocks a path of movement of the first actuating mechanism and in the second position the sliding bar blocks a path of movement of the second actuating mechanism. The one or more retaining protrusions frictionally engage the sliding bar when the sliding bar is in the first position and holds it in place, preferably with a frictional force sufficient to resist the force of gravity and/or vibrations.
