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.

摘要： A circuit interrupter including a housing, separable main contacts within the housing, and an operating mechanism within the housing and interconnected with the separable main contacts. A trip mechanism is disposed within the housing that includes a trip bar assembly rotatable about an axis and that, when rotated, generates a tripping operation causing the operating mechanism to open the contacts. The trip bar assembly includes a trip member translatable along the axis. The trip mechanism includes a tripping actuator movable along a predetermined path of travel as a function of electrical current. The tripping actuator contacts a contact area of the trip member at a predetermined location along the predetermined path of travel of the tripping actuator and causes the trip bar assembly to rotate and generate the tripping operation upon a predetermined current threshold. When the trip member is translated along the axis, the contact area is contacted by the tripping actuator at a different location along the predetermined path of travel of the tripping actuator whereby the predetermined current threshold is changed.

摘要： An electric operator having a reciprocally mounted actuator is adapted to be mechanically coupled to an operating handle from a molded case circuit breaker or a molded case switch for moving the operating handle between an open position or, alternatively, to a closed position. The electric operator includes an electric motor for driving the actuator and allowing the circuit breaker to be controlled from a remote location and a mechanical crank assembly which alternatively allows for manual operation of the actuator in the event of a loss of electric power to the electric motor.

摘要： A laminated contact assembly formed from a plurality of contact arm subassemblies includes a contact arm portion, for carrying a movable main or arcing contact, and a stationary conductor portion. A flexible shunt, form wound from a flat electrical conductor, is used to connect the contact arm portion to the stationary conductor portion. The flexible shunt is formed into a V-shape defining two depending legs. The free ends of the shunt defining bulb portions are inserted into keyholes formed in the contact arm portion and the stationary conductor portion. A pin is inserted into a central portion of the bulb portion to exert radially outward forces against the interior surface of the keyhole to increase the contact force between the bulb portions and the keyholes to form joints having a lower electrical resistance. The pin may be inserted into the central portion of the bulb portion by orbital riveting.
