Abstract: A power drive mechanism for a circuit breaker handle which includes a reversible electrical motor, a carriage assembly and a cooperating slide plate assembly mechanically coupled to the motor shaft. The carriage assembly includes a pivotally mounted L-shaped lever, interlocked with the circuit breaker operating handle for driving the operating handle to an on position or alternatively to an off position on command. Microswitches are located at both the on position and the off position for controlling operation of the motor. The microswitches are actuated by the slide plate assembly which, in turn, is driven by the carriage assembly. The slide plate assembly is slidably mounted with respect to the carriage assembly with one or more wave washers. The slide plate assembly provides mechanical damping for the carriage assembly to minimize damage to the microswitches. The slide plate assembly also prevents the contacts in the limit switch from bouncing even though the carriage assembly may oscillate at the end of travel.

IPC: H01H9/46
CPC classification number: H01H9/46
Abstract: Briefly, the present invention relates to a molded case circuit breaker. The molded case circuit breaker includes at least one pair of separable main contacts, mounted on upper and lower contact arms. One end of the lower contact arm is formed as a U-shaped portion defining depending leg portions and a bight portion forming a reverse current loop. Disposed adjacent the lower main contact on the lower contact arm is an arc runner assembly which directs the arc resulting from a separation from the upper and lower main contacts into an arc chute to quench the arc. The arc runner assembly includes an arc runner and a support block. The arc runner may be formed from steel and is carried by the support block, disposed between depending leg portions of the lower contact arm. The support block is formed from an electrically insulating material, such as a glass polyester. The support block fixes the arc runner adjacent the main contact on the lower contact arm and also prevents bending of the lower contact arm due to repeated operations of the circuit breaker which can affect the normal contact pressure between the main contacts. The arc runner is provided with a downwardly extending retaining boss received in an aperture in the support block to provide mechanical retention of the arc runner with respect to the support block. The support block is mechanically positioned relative to the lower contact arm.

Abstract: A laminated contact assembly is formed from a number of individual contact assemblies. Each individual contact assembly includes a contact arm portion, which carries a movable main or arcing contact and a stationary conductor portion. A flexible shunt is used to connect the contact arm portion to the stationary conductor portion. Intermediate individual contact assemblies are provided with T-shaped slots for receiving square-headed fasteners. These square-headed fasteners are captured by adjacent assemblies once the laminated contact assembly is complete. By providing such an arrangement, the need to drill and tap holes in the base of the laminated contact arm assembly is obviated. Since all of the individual contact arm assemblies are fastened together, the possibility of the square-headed fasteners disposed in T-shaped slots in intermediate individual contact arm assemblies is greatly reduced. The flexible shunt is wound from a continuous strip of an electrical conductor and formed into a V-shaped member having extending leg portions which generate magnetic repulsion forces during overcurrent conditions. By utilizing a form wound shunt the cost of the contact arm assembly can be greatly reduced.

Abstract: A molded case circuit breaker includes a movable upper electrical contact carried by a contact member having an end portion with an arcuate cam surface formed thereon for engaging an outwardly projecting cam surface of a leaf spring. The leaf spring is secured to and disposed around an enlarged portion of a rotatable cross-bar of the operating mechanism of the circuit breaker. The leaf spring has an outwardly protruding cam surface and is mechanically configured to provide sufficient biasing force to the end portion of the movable upper electrical contact member to enable the upper electrical contact member and upper contact to move in unison with the cross-bar during normal operation of the breaker. Upon the occurrence of a high level short circuit or fault current of sufficient magnitude, the upper electrical contact rotate member and upper and the arcuate cam surface thereof is moved against the then stationary cam surface of the leaf spring. The arcuate cam surface of the leaf spring and the arcuate cam surface of the end portion of the contact member are configured to provide decreased biasing force as the upper electrical contact member rotates to its BLOWN-OPEN position. A detent or groove is formed along the arcuate cam surface of the end portion of the contacts member for receiving the outwardly projecting cam surface of the leaf spring to retain the movable upper electrical contact and contact member in a BLOWN-OPEN position, thereby minimizing the possibility of contact restrike.
