摘要： A contact blade for a circuit breaker configured such that the current path in the blade produces a magnetic field which affects an arc present at the contact of the blade. The configuration of the blade produces a substantially U-shaped current loop in the blade, wherein one leg of the current loop has its main component substantially parallel to, but in the direction opposite to, the main component of the current in the second leg of the loop. When an arc is formed at the contact, the current from the second leg flows through the contact and into an arc, while the current in the first leg of the loop produces a magnetic field which acts upon the arc and forces the arc off of and away from the contact.

摘要： A pivoting electrical connected useable in a molded case circuit breaker including a pair of contact plates for contacting the circular contact member of a contact carrying arm. The pivoting electrical connection provides at least three contact locations between the contact plates and the circular contact member. The contact locations provide current paths between a first terminal coupled to the contact plates and an electrical contact fixed to the contact carrying arm. The pivoting electrical connection allows the contact on the arm and an electrical contact coupled to a second terminal to be opened and closed.

摘要： A single piece contact barrier for separating and maintaining the spacing of the contact blades in a circuit breaker. The barrier is also adapted to form an insulating barrier between the contact blades and produce an arc quenching vapor. Under certain circumstances, when one contact and its associated contact are separated, an arc is formed between the contacts. The heat generated by the arc causes the barrier to vaporize in near the arc such that the vapor tends to quench the arc.

摘要： An assembly adapted to commutate arcs from between the main contacts of a circuit breaker to an arcing contact such that a single arc at the arcing contact can be extinguished and dispersed within an arc chute. The assembly is adapted to be pivotally attached to the ends of the main contact carrying arms and includes arc channeling members joined to form a contact surface. An arcing contact can be fixed to the contact surface such that the arcs from the main contacts are channelled into one arc at the arcing contact.

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 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).
