摘要： A charging handle assembly for charging the closing springs of a stored energy mechanism which closes the contacts of a circuit breaker. The charging handle has a generally U-shape and is pivotally attached to the circuit breaker cover. The handle is adapted to cooperate with the stored energy mechanism such that the cover and handle are easily removed from the circuit breaker. Additionally, the handle cooperates with the cover and the stored energy mechanism so that energy is transferred to the springs of the mechanism by pumpiing the handle.

摘要： A mechanism for accumulating and storing mechanical energy, wherein the energy is used to close the primary contacts of a circuit breaker. The energy can be input to the mechanism manually or by means of a motor. The mechanism includes a series of linkages which function to utilize the energy to close the primary contacts. These linkages also function to maintain the closing force upon the primary contacts, while also functioning to allow rapid contact opening when desired.

摘要： A circuit breaker including a trip unit interlock. The trip unit interlock provides a trip unit having a plug connectable with a mating plug which is slidable with respect to the circuit breaker. The trip unit engages a pair of pins mounted to the circuit breaker when the trip unit is in its operating position. The pins are oriented to prevent separation of the plug from the receptacle during circuit breaker tripping. Since it is undesirable to insert a trip unit into a circuit breaker where the trip unit is not compatible with the circuit breaker, the pins and openings in the trip unit are configured such that they will not mate if the trip unit is not appropriate for the circuit breaker. When the trip unit is in its operating position, the trip unit holds an interlock lever for the contact operating mechanism of the circuit breaker in a position where the contact operating mechanism may close the contacts and hold the contacts closed when the circuit breaker is in its ON state.

摘要： A circuit breaker (10, 12) includes a sensing circuit (48, 50, 52), a control circuit (46), an actuator (42), an operating mechanism, and an interlock mechanism (70, 94). The sensing circuit (48, 50, 52) is configured to generate the sense signal representative of a power signal flowing through a power circuit (54, 56, 58). The control circuit (46) has a frame (74, 76) and is configured to receive the sense signal and to provide a trip signal on a first terminal (68). The actuator (42) is external to the control circuit frame (74, 76) and has a second terminal (98) coupleable to the first terminal (68). The actuator (42) is configured to receive the trip signal on the second terminal (98). The operating mechanism is coupled to the actuator (42) and is configured to open and close the power circuit in response to actuation of a lever (36). The actuator (42) is configured to actuate the lever (36) in response to the trip signal. The interlock mechanism (70, 94) is coupled to at least one of the actuator (42) and the operating mechanism and is configured to actuate the lever (36) when the first terminal (68) is not coupled to the second terminal (98).

摘要： A circuit breaker housing includes a base having a main portion and a separate subbase portion. The line contact arms for the breaker are mounted on the subbase portion and attached to the main portion which includes the load contact arms. The main portion of the base includes a bottom wall which insulates the load contact arms from the line contact arms along a portion of their lengths. In addition, the bottom wall forms a structural member which rigidly ties the two sidewalls of the main portion of the base. The bottom wall of the main portion of the base includes an opening through which line contacts coupled to the line contact arm make contact with load arm contacts coupled to the load contact arms. Adjacent to the opening, the main portion of the base includes vertical ribs directly tied to the bottom wall which strengthen internal and external side walls in the main portion of the base and reinforce the structural member formed by the bottom wall of the main portion of the base. The subbase may be attached to the base with screws, adhesives, a combination of screws and adhesives or by other methods.

摘要： A primary disconnect assembly for a circuit breaker. The assembly includes a plurality of contact fingers for engaging the terminals of a bus bar assembly. The terminals and fingers are configured such that the terminals each include depressions adapted to accept the contact portions of the contact fingers. This configuration provides at least two contact locations between each contact finger and terminal. Additionally, this configuration increases the force required to slide the fingers relative to the terminals.
