摘要： A circuit breaker having stationary and movable contacts operable between open and closed positions. Movement effecting means causes relative movement of the movable contact between open and closed positions, and a closing spring assembly imparts movement to the movement effecting means to move the movable contact to the closed position. The closing spring assembly includes first and second members and a helical closing spring, with the first and second members extending into the central opening of the spring. Shock absorbing means is disposed within the spring opening to absorb energy released when the assembly is discharged.

摘要： A molded case circuit breaker includes a new and improved calibration adjusting means for a bimetal in a trip mechanism. The trip mechanism also includes a bimetal having a portion movable in response to predetermined overload conditions, an intermediate control lever for adjusting the spatial disposition of the movable portion of the bimetal with respect to a trip bar of the trip mechanism and a rotatable adjustment means for adjusting the spatial disposition of the intermediate control lever in the circuit breaker. By rotating the adjustment means, the distance between the movable portion of the bimetal and the trip bar can be precisely adjusted via the intermediate control lever. The intermediate control lever is coupled to a relatively stationary portion of the bimetal thereby enabling such adjustment without applying undue stress to the movable portion of the bimetal.

摘要： Electrical switches and circuit breakers in which the contacts and operating mechanism are enclosed within an insulating housing by an insulating cover and which have an elongated operating handle extending through an elongated slot in the cover have an enlarged terminal portion of the operating handle which is wider than the slot to prevent removal of the cover except in positions of the handle at which the electrical contacts are open and the slot is wider than the terminal portion of the handle. Preferably, this is only the OFF position of the switch or breaker, however, in circuit breakers with a notch at the trip position to expose indicia indicating the breaker operating condition, a transverse pin through the operating handle permitting removal of the cover only with the operating handle in the trip position, provides an economical backfit.

摘要： An arc chute assembly for a circuit breaker or similar device comprising a series of metallic arc chute plates that are locked in stacked spaced-apart relationship between a pair of insulative side panels by elongated key members of non-conductive material that are wedged between the flat surfaces of the side panels and notched portions of pairs of T-shaped tabs which extend from each side edge of the respective plates. The tabs interlockingly engage a series of laterally-extending slot openings in the side panels in such a manner that the key members are in press-fitted engagement with only one of the tabs in each pair of tabs.

摘要： A circuit breaker having stationary and movable contacts operable between open and closed positions with the movable contact being biased in an open position. The movable contact is mounted to a contact holder which engages one link in a toggle means. The first link is connected to a second link which has a drive pin secured thereto, and the second link is pivotally connected to a toggle lever. A cam is secured to a rotatable drive shaft, and the cam engages a cam roller which is secured to a follower plate. The follower plate has a drive pawl attached thereto, with the drive pawl being disposed adjacent the drive pin. Spring means are pivotally connected to the follower plate and are capable of being in spring charged and discharged positions. The spring is charged by rotation of the drive shaft and cam causing the cam roller to move outwardly. The outward movement of the cam roller causes rotation of the follower plate, resulting in charging of the spring means. When the spring means discharges, it causes rotation of the follower plate such that the drive pawl is capable of engaging the drive pin to move the toggle means into toggle position. Upon moving into toggle position, the toggle means moves the contact holder and movable contact into closed position. Also included are releaseable toggle and drive latch means for holding the toggle means in toggle position and the follower plate in the spring charged position, respectively. Means for rotating the drive shaft include a handle secured to the drive shaft and a motor operator having a rotatable output shaft which is capable of engaging the drive shaft and which can be easily installed. A motor and handle clutch is used to prevent rotation of the handle upon rotation of the motor, and to prevent rotation of the motor upon rotation of the handle.

摘要： A telescoping high current disconnect switch for isolated phase bus includes a pair of axially spaced cylindrical fixed conductors insulatingly mounted within a cylindrical aluminum housing. An aluminum telescope section is coaxial with the fixed conductors and is insulatingly mounted upon a plurality of rollway pillow blocks each containing ball bearings. The pillow blocks are supported by guide rails of austenitic non-ferromagnetic stainless steel which are attached to the interior surface of the housing. The telescope section is axially movable along the guide rails to bridge the fixed conductors, such movement causing the ball bearings to cold-form grooves in the rails, whereby portions of the rails are work-hardened.

摘要： An isolated phase bus disconnect switch has a cylindrical aluminum center conductor coaxially disposed within a cylindrical aluminum housing. The center conductor is composed of two fixed axially spaced sections and a coaxial telescoping sleeve assembly which moves axially to make and break electrical contact between the fixed sections. One end of each fixed section and both ends of the sleeve assembly have copper contact rings fixedly attached thereto. Adjoining surfaces of the copper-aluminum interfaces are silver plated, and each of the adjoining aluminum members is axially slotted to permit flexing to allow for differential thermal expansion, while at the same time preventing relative motion between the plated surfaces.

摘要： A miniature circuit breaker incorporating ground fault protection and arc fault protection includes main separable contacts. An operating mechanism actuated by a trip mechanism opens the main separable contacts in response to predetermined current conditions. Auxiliary separable contacts are disposed in series with the main separable contacts. A solenoid having a movable plunger opens and closes the auxiliary separable contacts in response to a remote external signal. A ground fault trip circuit detects a ground fault, and an arc fault trip circuit detects an arc fault. An actuator mechanism, energizable by the ground fault trip circuit and the arc fault trip circuit, actuates the plunger to open the auxiliary separable contacts.
