US Patent:

7839243, Nov 23, 2010

Filed:

Jan 8, 2008

Appl. No.:

11/970552

Inventors:

Hai Chen - Duluth GA, US
John D Stephenson - Roswell GA, US

Assignee:

Siemens Industry, Inc. - Alpharetta GA

International Classification:

H01H 9/30
H01H 9/36

US Classification:

335201, 218 34, 218149, 218150, 218151

Abstract:

Certain exemplary embodiments can provide a system, which can comprise a set of substantially planar arc plates. The substantially planar arc plates can be adapted to cause a dissipation of energy caused by an arc in a circuit breaker. A housing can be adapted to receive each of the set of substantially planar arc plates.

Assignee:

Siemens Industry, Inc. - Alpharetta GA

International Classification:

H01H 75/00

US Classification:

335 6, 335 21

Abstract:

The present invention relates generally to a plastic cradle. More particularly, the invention encompasses a plastic cradle utilized inside a molded circuit breaker (MCB). The present invention is also directed to a novel nonconductive nonmagnetic cradle that engages a contact arm between a first terminal conductor and a second terminal conductor inside a molded circuit breaker (MCB) in an ON state, and disengages same in an OFF or Neutral state.

Filed:

Oct 5, 2010

Appl. No.:

12/898236

Inventors:

Hai Chen - Duluth GA, US
Larry Navarre - Norcross GA, US
Hector Malacara - Norcross GA, US

Assignee:

Siemens Industry, Inc. - Alpharetta GA

International Classification:

H01H 33/02

US Classification:

218154

Abstract:

A circuit breaker which includes first and second contact pairs and a contact arm arranged in series. A first arm contact and a first terminal contact from a first line terminal form a first contact pair. A second arm contact and a second terminal contact from a second line terminal contact form a second contact pair. The first contact pair, contact arm and second contact pair are connected in a series arrangement in which the air gaps formed when the first and second contact pairs are separated combine to form an effective air gap which is double in size and thus increases an interrupting capacity of the circuit breaker. An arc chamber is associated with the first and second contact pairs for extinguishing an arc formed in the air gaps. The first and second contact pairs may also be arranged in a parallel configuration for increasing an amperage rating of the circuit breaker.

Filed:

Jun 30, 1995

Appl. No.:

8/497305

Inventors:

Hai Chen - Salisbury MD
George W. Evans - Salisbury MD
Leo V. Zirpoli - Berlin MD

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

H01H 920

US Classification:

200 5002

Abstract:

An electrical power switch assembly has a disconnect switch electrically connected to a circuit breaker mounted within an enclosure having a hinge cover where the disconnect switch has a movable element that opens and closes electrical contacts. The movable element is pivotably connected to the cover using a switch link such that the opening of the cover causing the switch link to pull the movable element causing the electrical contacts to open. A breaker link that extends outside the enclosure is used to activate and deactivate the circuit breaker.

Appl. No.:

16/025511

Inventors:

- Alpharetta GA, US
Russell Thomas Watford - Lawrenceville GA, US
Hai Chen - Duluth GA, US

International Classification:

H02H 3/08
H02H 1/00
H01H 71/10
H04B 17/20

Abstract:

A smart residential circuit breaker includes a hybrid assembly that incorporates a solid-state circuit element integrated into a simplified mechanical pole having main contacts. The solid-state circuit element includes a printed circuit board (PCB) with a micro SD reader to provide faster opening speeds. The smart residential circuit breaker is configured for use for different current levels and controlled by the PCB. The smart residential circuit breaker includes a mag-latch. The PCB is configured to send a signal to the mag-latch to open and close the main contacts within microseconds of detecting an over-current.
