US Patent:

53215745, Jun 14, 1994

Filed:

Jan 17, 1992

Appl. No.:

7/822509

Inventors:

John R. Patrick - Stone Mountain GA
James S. Wells - Lawrenceville GA

Assignee:

Siemens Energy & Automation, Inc. - Alpharetta GA

International Classification:

H02H 904

US Classification:

361 99

Abstract:

A circuit breaker/surge arrestor package for plug-in installation in the space of two standard one-inch openings in a contemporary residential load center. The electrical and thermal characteristics of the components are selected such that a threshold of a substantially continuous current through a Metal Oxide Varistor in the surge arrestor causes the circuit breaker to trip magnetically before being able to trip thermally.

Assignee:

Siemens Energy & Automation, Inc. - Alpharetta GA

International Classification:

H01H 926
H02B 1100

US Classification:

200 5033

Abstract:

A cable interlock system is provided for preventing at least two circuit breakers from both being closed, comprising: a first circuit breaker assembly comprising a first main contact, a first cross bar, a first cross bar plunger, a first transfer assembly and a first operating handle, wherein the first operating handle is adapted to close or open the first circuit breaker assembly, and wherein the first cross bar plunger is adapted to contact the first cross bar, and wherein the first transfer assembly is adapted to move the first cross bar plunger; a second circuit breaker assembly comprising a second main contact, a second cross bar, a second cross bar plunger, a second transfer assembly and a second operating handle, wherein the second operating handle is adapted to close or open the second circuit breaker assembly, and wherein the second cross bar plunger is adapted to contact the second cross bar, and wherein the second transfer assembly is adapted to move the second cross bar plunger; a cable assembly having one end adapted for association with the first transfer assembly and having another end adapted for association with the second transfer assembly, wherein the one end of the cable assembly and the first transfer assembly cooperate with the first cross bar and the first cross bar plunger, and the another end of the cable assembly and the second transfer assembly cooperate with the second cross bar and the second cross bar plunger so as to prevent the first main contact and the second main contact from both being closed.

Appl. No.:

7/317892

Inventors:

Gustav Witzmann - Atlanta GA
John R. Patrick - Stone Mountain GA

Assignee:

Siemens Energy & Automation, Inc. - Alpharetta GA

International Classification:

H01H 926

US Classification:

200 50C

Abstract:

A mechanical interlock for interlocking two circuit breakers such that only one of the circuit breakers is ON at a given time. The interlock is also configured such that it permits both circuit breakers to be OFF at the same time. The interlock includes a pivoting rocker arm and a linkage assembly associated with each breaker, wherein the rocker arm and linkage assemblies cooperate to transfer motion between the tie bars of the circuit breakers.

Appl. No.:

7/282154

Inventors:

Eduard Zubar - Stone Mountain GA
John R. Patrick - Stone Mountain GA

Assignee:

Siemens Energy & Automation, Inc. - Atlanta GA

International Classification:

H01M 2710

US Classification:

200 4314

Abstract:

An apparatus for locking the switch handle of a circuit breaker in the ON or OFF position. The apparatus includes a blocking member mountable on the handle with two screws, a pivoting member pivotable about the screws and a lock for locking the blocking member to the pivoting member. When the blocking member and the pivoting member are locked together, the blocking member is maintained in a position such that it interferes with the circuit breaker housing and prevents the handle from being moved.
