58218394, Oct 13, 1998

Filed:

Aug 23, 1996

Appl. No.:

8/697383

Inventors:

James Arthur Heise - Cedar Falls IA
Duane Lee Turner - Cedar Rapids IA
Dennis William Fleege - Cedar Rapids IA
Eugene Walter Wehr - Cedar Rapids IA

Assignee:

Square D Company - Palatine IL

International Classification:

H01H 7512

US Classification:

335 35

Abstract:

A circuit breaker device for interrupting current in a circuit path between a source and a load includes a first contact and a second contact cooperatively arranged in the circuit path so as to provide current from a source to a load. A trip mechanism assembly, which includes an armature, a bimetal and a yoke, is provided for interrupting the current. The armature includes an aperture in which a latch point is provided to engage a latching surface of a trip lever for latching the trip lever thereon. The amount of current that is required to cause the trip mechanism to interrupt the circuit path is determined by the amount of overlap between the latching surface and the latch point. This overlap is adjusted by bending a calibration plate by tightening a calibration screw which extends through an aperture in a circuit breaker housing and a slotted aperture in the calibration plate. A substantially square shaped nut secures the calibration screw tightly against the housing.

International Classification:

H01H 7300

US Classification:

335 18

Abstract:

A compact coil assembly is provided for protecting electrical components from transient voltage surges. The assembly includes a bobbin having a cylindrical core with two ends. A first and second flange are each perpendicularly mounted and extended outwardly from one of the ends. A lead pin is perpendicularly upstanding on the top surface of the first flange. The first flange has a parallel outer and inner wall defining a channel therebetween. The inner wall has a slot therethrough. The slot is open at one end to the top surface of the first flange and extends downward to the core. The slot is positioned on the top surface of the first flange opposite the lead pin. The channel extends from the lead pin across to the end of the slot near the core. The width of the channel and the slot are adapted for guiding a winding wire therethrough.

International Classification:

H01H 8300

US Classification:

335 20

Abstract:

A remotely controllable circuit breaker device for interrupting current in a circuit path between a source and a load includes local and remote monitoring capabilities and a gear mechanism for reliable remote control of the interruption mechanism. The device includes a first contact and a second contact cooperatively arranged in the circuit path so as to provide current from the source to the load. At least one of the contacts is disposed on a contact carrier which is movable for interrupting the current provided to the load. The gear mechanism includes a motor with a rotatable shaft which responds to open and closed control signals generated from a remote location, and a gear, rotatably responsive to the rotatable shaft, for controlling the contact carrier so that the circuit path is interrupted and established, respectively. The gear mechanism controls the contact carrier using a coupling arrangement, which has a first part coupled to the contact carrier and a second part coupled to the gear. A manual override mechanism is utilized to render the coupling arrangement non-responsive to the motor.

Assignee:

Square D Company - Palatine IL

International Classification:

H01H 300

US Classification:

335 68

Abstract:

A coupling member for securing a spring to a rotatable motor shaft so that the spring rotates with the motor shaft. The coupler has a cylindrical hollow middle which fits snugly onto the motor shaft and includes a main body portion having a smaller cylindrically shaped nose portion extending therefrom for receiving one end of the spring therearound. The main body portion includes a ramp portion, extending upwardly therefrom, a wall behind the ramp portion and a slot therein for receiving a hook portion extending from the spring. The hook portion is snugly secured in the slot and behind the wall so that as the motor shaft rotates, the coupler member causes the spring to rotate with the motor shaft.

Abstract:

A circuit breaker device for interrupting current in a circuit path between a source and a load. The device includes a first contact and a second contact cooperatively arranged in the circuit path so as to provide current from the source to the load. At least one of the contacts is disposed on a contact carrier which is movable for interrupting the current provided to the load. A contact status indication arrangement is provided for indicating the status of the contacts. The contact status indication arrangement includes a trip flag, a status insert, a clear plastic lens, a flag guide, and a status flag. The trip flag, status insert and status flag are viewable through the lens, which is disposed in an aperture in the circuit breaker housing. Only one status indicator is viewable through the lens at any one time, each indicating a different circuit breaker status. For example, when the trip flag is visible, the circuit breaker is in the TRIPPED position; when the status insert is visible, the circuit breaker is in the OPEN position; and when the status flag is visible, the circuit breaker is in the CLOSED position.
