Filed:

Feb 28, 2000

Appl. No.:

09/514458

Inventors:

Kevin Anthony Simms - Library PA
Wayne Gerald Adamson - Coraopolis PA
David Lee Davidson - Camden SC
Kenneth L. Uhlman - Moon Township PA

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

H01H 7300

US Classification:

361115, 335 14

Abstract:

A circuit breaker has a set of remotely controllable secondary contacts connected in series with the main contacts which provide overcurrent protection. The secondary contacts are opened and closed by a latching solenoid having a close coil and an open coil which are separately connected to switched terminals of a first switch. A voltage source, which may be ac, dc or pulsed, is connected to the common terminal of the first switch through a rectifier. The first switch is coupled to the plunger of the latching solenoid which opens and closes the set of secondary contacts and enables the coil which operates the set of secondary contacts to the opposite state. Energization of the enabled coil is completed by additional, remotely located switches connected between each coil and ground. A status line connected to one of the switched terminals of the first switch is energized when the associated coil is enabled to indicate the open/close status of the set of secondary contacts.

International Classification:

H02H 300

US Classification:

335 6, 335 13, 335 14, 361115

Abstract:

A circuit breaker has a set of remotely controllable secondary contacts electrically connected in series with the main contacts which provide overcurrent or fault current protection. An operating mechanism opens and closes the set of main contacts. The secondary contacts are opened and closed by a latching solenoid. The latching solenoid includes a plunger latchable to a first position, which opens the set of secondary contacts, and to a second position which closes the set of secondary contacts. The latching solenoid also includes an open/close coil which when energized with a first polarity signal operates the plunger to the first position and which when energized with an opposite second polarity signal operates the plunger to the second position. A circuit is structured for cooperation with a remote control circuit for energizing the coil with the first polarity signal or, alternatively, the second polarity signal.

International Classification:

H01H 7500

US Classification:

335 6, 335 13, 335186, 200240, 200DIG 42

Abstract:

A circuit breaker includes a housing having an elongated pivot opening, a movable arm, a fixed contact and a movable contact mounted on the arm. The contacts and the arm cooperate to provide closed, pivot and open states. The pivot opening mounts a pivot end of the arm for pivotal and longitudinal movement. A solenoid includes a plunger coupled to the arm. The plunger moves between deactuating and actuating positions to provide the open and closed states, respectively. The plunger has a pivot position between the deactuating and actuating positions. The pivot end moves to a first longitudinal position in the pivot and open states, and moves to a second longitudinal position in the closed state. When the contacts are welded closed, the solenoid provides insufficient force to move the plunger to the deactuating position until after the pivot end moves at least substantially toward the first longitudinal position.

International Classification:

H01H 7500

US Classification:

335 14, 335 20, 335172, 335202

Abstract:

A circuit breaker includes a housing, separable contacts, an operating mechanism having a pivotally mounted operator handle for opening and closing the separable contacts, and a trip mechanism releasing the operating mechanism to move the operator handle to its tripped position. A micro-switch includes an actuator lever movable between an actuated position and a non-actuated position and adapted to engage a surface of the operator handle. The micro-switch also includes a normally open contact having a closed state corresponding to the actuated position and an open state corresponding to the non-actuated position. The operator handle surface engages and moves the actuator lever to the actuated position in only the ON position of the operator handle. The actuator lever is in the non-actuated position in the OFF position and the tripped position of the operator handle.

International Classification:

H01H 7700

US Classification:

335 14, 335 20

Abstract:

A transfer switch includes a miniature circuit breaker housing, a first line terminal, a second line terminal and a load terminal. A transfer arm is adapted to pivot between a first position in which the transfer arm is electrically connected to the first line terminal and a second position in which the transfer arm is electrically connected to the second line terminal. A solenoid having a first coil, a second coil and a plunger moves the transfer arm between the first and second positions thereof. Separable contacts are electrically connected between the transfer arm and the load terminal. An operating mechanism opens and closes the separable contacts.

International Classification:

H01H 8300

US Classification:

335 6, 335 18, 335 20

Abstract:

A remotely controllable circuit breaker includes main contacts, secondary contacts and an arc plate drawing an arc from a fixed main contact when an operating mechanism opens the main contacts. A primary circuit electrically connects the main and secondary contacts between line and load terminals. A solenoid actuator selectively moves the secondary contacts between open and closed states. A magnetic bypass circuit is electrically connected between the arc plate and the load terminal. A movable magnetic armature cooperates with a fixed magnetic armature and is coupled to a movable arm controlled by the actuator. The circuits pass between the magnetic armatures, which respond to short circuit current flowing in the primary circuit and to arcing current flowing in the magnetic bypass circuit, in order to hold the secondary contacts in the closed state during both current conditions.
