US Patent:

58214852, Oct 13, 1998

Filed:

Apr 25, 1997

Appl. No.:

8/842951

Inventors:

Paul H. Singer - West Hartford CT
Paul T. Rajotte - Plainville CT

Assignee:

General Electric Company - New York NY

International Classification:

H01H 7174

US Classification:

200 17R

Abstract:

A circuit breaker trip unit enclosure is adapted to receive rotary knobs that are limited in rotation in proportion to the circuit breaker short circuit rating. The externally-accessible rotary knobs extend within the enclosure to contact with a potentiometer affixed to the circuit breaker trip unit printed circuit board. A stop member is inserted within the enclosure access opening to detent the rotary knob shank that extends through the access opening.

Appl. No.:

8/767747

Inventors:

Raymond K. Seymour - Plainville CT
Paul H. Singer - West Hartford CT
David Arnold - Chester CT

Assignee:

General Electric Company - New York NY

International Classification:

H02H 300

US Classification:

361 93

Abstract:

Each pole of a multi-pole circuit breaker is equipped to individually separate the circuit breaker contacts within each pole upon overcurrent occurrence. A digital processor within the circuit breaker trip unit determines the occurrence of zero current crossing of phase current within the individual poles and initiates contact separation at zero current values.

Filed:

May 25, 1994

Appl. No.:

8/248910

Inventors:

John A. Pollman - Seymour CT

Paul T. Rajotte - Plainville CT

Assignee:

General Electric Company - New York NY

International Classification:

H01H 2300

US Classification:

200401

Abstract:

A combined bell alarm and lock-out accessory is connected with the electronic trip unit that controls a high ampere rated circuit breaker. The accessory interacts with the circuit breaker operating mechanism to activate the bell alarm upon circuit interruption and to prevent the closing of the circuit breaker contacts until the accessory is manually reset.

Appl. No.:

9/035191

Michael R. Koller - Plainville CT

Assignee:

General Electric Company - Schenectady NY

International Classification:

G01R 3132

US Classification:

324424

Abstract:

A method of initializing short time and groundfault protection heat index accumulators to compensate for current flow during the time interval between the application of phase current and application of current measurement and protection algorithms in an electronic trip unit is presented. The electronic trip unit includes a microcontroller and associated ROM having trip unit application code, e. g. , main functionality firmware, including initializing parameters, and boot code, stored therein and EEPROM having operational parameter code, e. g. , encoded enumerations for parameters such as 50/60 Hz. , UL/ANSI/IEC, etc. , stored therein. The time internal comprises first and second time components. The first time component is the time between the instant phase currents are applied and the instant the microcontroller is initialized and the second time component is the time between the instant the microcontroller is initialized and the instant the microcontroller begins execution of short time and groundfault algorithms (i. e. , protection algorithms).

Assignee:

General Electric Company - New York NY

International Classification:

H02H 300

US Classification:
