Two-Pole Compartmentalized Ground Fault Miniature Circuit Breaker With Increased Current Rating
US Patent:
5453723, Sep 26, 1995
Filed:
Jun 23, 1994
Appl. No.:
8/264572
Inventors:
Joseph P. Fello - Verona PA
Michael J. Whipple - Oakdale PA
Michael J. Whipple - Oakdale PA
Assignee:
Eaton Corporation - Cleveland OH
International Classification:
H01H 7300
US Classification:
335 18
Abstract:
A miniature circuit breaker with two thermal-magnetic poles has an electronic trip device providing ground fault, and sputtering arc fault (if desired), protection located entirely in a large central compartment of a molded housing between compartments housing the two mechanical poles. The current rating of the circuit breaker is increased by a gas vent channel extending between the two mechanical pole compartments adjacent the respective breaker contacts which allows gases generated by arcing during current interruption to expand into both outer compartments, thereby permitting the circuit breaker to interrupt larger short circuit currents. The gas vent channel extends through, but does not communicate with, the central electronics compartment.
Ground Fault Circuit Breaker

International Classification:
H02H 300
US Classification:
361 42
Abstract:
A reverse fed single pole miniature ground fault circuit breaker includes a housing, a line termination on the lower portion of the housing, and a load termination on the upper portion of the housing. Separable contacts are disposed between the line termination and the load termination. A handle and operating mechanism form a manual mechanism for manually operating the separable contacts. The handle has an upper position in which the separable contacts are closed and a lower position in which the separable contacts are open. A ground fault circuit interruption trip circuit opens the separable contacts in response to predetermined ground fault current conditions and is powered through those separable contacts. In this manner, when a power source is electrically interconnected with the line termination on the lower portion of the housing, when the handle is in the upper position, and when there is none of the predetermined ground fault current conditions, the ground fault circuit interruption trip circuit receives power through the separable contacts.
Circuit Breaker Including A Cradle And A Pivot Pin Therefor
US Patent:
6894594, May 17, 2005
Filed:
Jun 20, 2003
Appl. No.:
10/601056

Russell T. Borona - Gurabo PR, US
Assignee:
Eaton Corporation - Cleveland OH
International Classification:
H01H009/00
US Classification:
335172, 335 35
Abstract:
A circuit breaker includes a molded housing having a base and a cover forming a recess. A cylindrical steel pivot pin is disposed in the recess of the housing. Fixed and movable separable contacts are disposed within the molded housing. An operating mechanism is disposed within the molded housing for moving the separable contacts between an open position and a closed position. The operating mechanism includes a cradle having a latch portion and a generally U-shaped pivot portion which pivotally engages the cylindrical steel pivot pin. A trip mechanism cooperates with the operating mechanism to trip open the separable contacts. The trip mechanism includes a portion which engages the latch portion of the cradle when the separable contacts are in the closed position.
