International Classification:
H01H 7500
US Classification:
335 15
Abstract:
A molded case circuit breaker includes an operating handle yoke that contacts the cradle operator and drives the operating mechanism springs over-center when the circuit breaker operating handle is moved from its RESET to its ON position. The contact between the handle yoke and cradle operator accelerates the over-centering of the powerful operating mechanism springs.
Bell Alarm And Lock-Out For High Ampere-Rated Circuit Breakers

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.

US Classification:
200144C
Abstract:
A current limiting circuit breaker having a pair of separable contacts closely spaced for electrodynamic repulsion upon the occurrence of a short circuit overload condition utilizes an arc chute to cool and extinguish the arc that occurs when the contacts become separated. The arc chute contains a plurality of metal arc plates supported by side plates which also assist in cooling and extinguishing the arc. The side plates are formed from a suspension of wollastonite fibers within a melamine resin matrix. The wollastonite provides good mechanical strength and temperature-resistance properties while the melamine provides a continuous source of arc-quenching gaseous molecular compounds.
Digital Circuit Interrupter Undervoltage Release Accessory
John A. Pollman - Seymour CT Raymond K. Seymour - Plainville CT Paul H. Singer - West Hartford CT
Assignee:
General Electric Company - New York NY
International Classification:
H02H 324
US Classification:
361 92
Abstract:
An integrated circuit breaker is described having undervoltage trip capability along with automatic overcurrent protection. The undervoltage accessory further provides auxiliary power to the trip unit and allows the trip unit to report and record the undervoltage release operation.
Digital Circuit Interrupter Shunt Trip Accessory Module
John A. Pollman - Seymour CT Raymond K. Seymour - Plainville CT
Assignee:
General Electric Company - New York NY
International Classification:
H02H 300
US Classification:
361 93
Abstract:
An integrated circuit breaker is provided with shunt trip capability along with automatic overcurrent protection through the circuit breaker trip unit and shunt trip module. The shunt trip module further provides auxiliary power to the trip unit and allows the trip unit microprocessor to report and record the shunt trip operation. The trip unit communicates with the circuit breaker operating mechanism to determine the ON-OFF status of the circuit breaker contacts.

International Classification:
H01H 7300
US Classification:
361115
Abstract:
A lockout solenoid is connected with the circuit breaker accessory shunt trip in a high ampere rated circuit breaker and interacts with the circuit breaker accessory lever to prevent the closing of the circuit breaker contacts until the shunt trip activation voltage signal is turned off. The circuit breaker accessory lever interlocks the circuit breaker closing button to prevent closing the circuit breaker contacts until such shunt trip activation voltage signal is turned off.
