Patent number: 4996507Abstract: A molded case circuit breaker is provided with a quick change current transformer assembly. The current transformer is used to sense overcurrent conditions and apply a signal to an electronic trip unit to trip the circuit breaker. The quick change assembly includes an insulated removable plate located adjacent an open cavity in the housing in which the current transformer is located. The current transformer is donut-type disposed about a load-side conductor located in a cavity in the housing rigidly fastened to the circuit breaker frame. In order to replace a current transformer, the insulated backplate is removed. Next the load-side conductor is unfastened and removed from the circuit breaker housing. The current transformer is then removed from the circuit breaker housing. In order to install a new current transformer, the steps are reversed. A force transmitting spacer is disposed adjacent a bight portion of a shunt, connected between a pivotally mounted contact arm and a load-side conductor.Type: GrantFiled: October 11, 1989Date of Patent: February 26, 1991Assignee: Westinghouse Electric Corp.Inventors: Jere L. McKee, Glenn R. Thomas, Lance Gula, William E. Beatty, Jr.

Patent number: 4983939Abstract: A circuit breaker has a magnetic trip assembly which can be adjusted to trip the breaker for low level overcurrents in the range of five to ten times rated current. The magnet trip includes for each pole of the breaker a helical torsion spring having one torsion arm which biases an armature against an adjusting bar to form a gap between the armature and a stationary magnetic structure in which magnetic flux strong enough to attract the armature and trip the breaker is induced by overcurrent. A second torsion arm of the spring has a first portion which bears against and slides along a pivot member carried by the adjusting bar to adjust the bias force applied to the armature by a given amount per unit travel of the adjusting bar over a low trip current portion of the range of travel of the adjusting bar.Type: GrantFiled: October 5, 1989Date of Patent: January 8, 1991Assignee: Westinghouse Electric Corp.Inventors: John J. Shea, Richard P. Sabol, Louis Paich, Ronald A. Cheski, Kenneth W. Sanner, William E. Beatty, Jr.

Patent number: 4891617Abstract: A molded case circuit breaker is provided with rubber stop assemblies disposed between the contact assemblies adjacent the outside poles and the cover portion of the housing. The rubber stop assemblies are disposed such that they prevent the contact assemblies from damaging the cover. The stop assemblies include a dual purpose U-shaped bracket having two parallel sets of arms. One set of arms is provided with aligned apertures at the free ends for receiving a pin which defines a pivot point for the crossbar assembly. The other set of arms is also provided with aligned apertures at the free end for receiving a metal pin for carrying a cylindrical shock absorber assembly. The shock absorber assembly is mounted adjacent outside poles above the contact carrier but spaced away from the inside of the cover of the circuit breaker. Thus, when the contact arm is opened, it will stop against the shock absorber and not damage the circuit breaker cover.Type: GrantFiled: August 1, 1988Date of Patent: January 2, 1990Assignee: Westinghouse Electric Corp.Inventors: William E. Beatty, Jr., Lawrence J. Kapples, Lance Gula, Joseph F. Changle

Patent number: 4794484Abstract: A circuit interrupter includes a circuit arrangement for sampling a conditioned current value and determining operating characteristics related to the current flow through an electrical circuit. Also included is a circuit arrangement for comparing the operating characteristics to preselectable tripping parameters and for initiating a trip condition when an operating characteristic exceeds a corresponding tripping parameter. Additionally, a circuit arrangement for initiating a hardware override trip condition using a minimum number of components upon sensing an override signal, is also included; the override signal representing a limit selectable from a range of values.Type: GrantFiled: February 20, 1987Date of Patent: December 27, 1988Assignee: Westinghouse Electric Corp.Inventors: Joseph J. Matsko, William E. Beatty, Jr., Raymond O. D. Whitt, Gary F. Saletta

Patent number: 4603313Abstract: A circuit breaker characterized by a pair of separable contacts, trip means operable automatically in response to overload current conditions to open the contacts which means include a rotatable trip bar biased in an untripped position, and interlock means including a manually operable button for rotating the trip bar to a tripped position when the button is pushed and for rotating a cam into tripped and untripped positions when the button is rotated.Type: GrantFiled: August 30, 1985Date of Patent: July 29, 1986Assignee: Westinghouse Electric Corp.Inventors: Alan B. Shimp, William E. Beatty, Jr.

Patent number: 4489295Abstract: A multiple pole circuit breaker comprises stationary and movable contacts in each pole, with a cross bar extending between the poles and causing concerted movement of the movable contacts. An operating mechanism effects movement of the movable contacts between open and closed positions, and a resettable undervoltage release mechanism cooperates with the operating mechanism to effect movement of the movable contacts. The undervoltage release mechanism operates to move the movable contacts from the closed to open position upon the occurrence of voltage levels less than a predetermined value, with the undervoltage release mechanism being reset by physical contact with the cross bar as the cross bar moves with the movable contacts from the closed to open positions.Type: GrantFiled: December 17, 1982Date of Patent: December 18, 1984Assignee: Westinghouse Electric Corp.Inventors: James N. Altenhof, Jr., Jere L. McKee, William E. Beatty, Jr.

Patent number: 4358810Abstract: A circuit breaker and alarm device for a circuit having a series connected interruptible current device whereupon a circuit breaker tripping means, attached to said circuit breaker, is adapted to obtain an output voltage of one polarity upon the tripping of the circuit breaker. A circuit breaker resetting device, attached to said circuit breaker, is adapted to obtain an output voltage of reverse polarity upon the resetting of the circuit breaker. A voltage-detecting circuit for sensing the voltage produced by the tripping or resetting of the circuit breaker. A current detecting circuit which produces an output upon detecting an output produced by the voltage-detecting circuit. An alarm circuit which is connected to the current-detecting circuit is thereby caused to essentially instantaneously upon the tripping of the circuit breaker, to energize and remain energized until the resetting of the circuit breaker.Type: GrantFiled: January 21, 1981Date of Patent: November 9, 1982Assignee: Westinghouse Electric Corp.Inventors: John A.

Patent number: 4220935Abstract: A molded case current limiting circuit breaker includes separable contacts, an operating mechanism releasable to effect automatic separation of the contacts, and a high speed electromagnetic trip device operable upon overcurrent conditions to release the operating mechanism and separate the contacts. The trip device includes a U-shaped pole piece disposed about a conducting path through the circuit breaker and a movable laminated armature mechanically coupled to the operating mechanism and magnetically coupled to the pole piece. The thickness of the armature is substantially greater than the thickness of the pole piece. During extreme overcurrent conditions electrodynamic force is produced upon the armature by magnetic flux in the pole piece. Upon saturation of the pole piece, force upon the armature continues to increase with increasing current due to electrodynamic force produced between the armature and the conducting path.Type: GrantFiled: October 16, 1978Date of Patent: September 2, 1980Assignee: Westinghouse Electric Corp.Inventors: John A. Wafer, William E. Beatty, Jr.
