MEANS FOR PROVIDING IMPROVED OPERATION PROPERTIES FOR ELECTRICALLY OPERATED CIRCUIT BREAKERS, DISCONNECT SWITCHES, AND CONTACTORS

摘要

Improved circuit breaker operation is achieved by a system that includes a circuit breaker unit and a secondary actuator. The secondary actuator is operable to place the circuit breaker unit into an inoperable position when de-energized and in an operable position when energized. When in the operable position, the circuit breaker can be energized to close its contacts into an ON position. The circuit breaker cannot operate on its own as it cannot be placed into an ON position when energized alone.

主权项

1. A circuit breaker assembly, comprising:
a circuit breaker unit; a secondary actuator operable to place the circuit breaker unit into an operable position when energized and maintain the circuit breaker in an inoperable position when de-energized.
