ABSTRACT:
A circuit breaker configured to be remotely operated is disclosed. The circuit breaker includes a set of main contacts configured to connect between an electrical source and an electrical load, an operating mechanism in operable communication to open and close the main contacts, and a remotely operable drive system configured to open and close the main contacts separate from actuation of the operating mechanism. The drive system includes a motor responsive to first and second control signals, a primary drive responsive to the motor, and an opening spring responsive to the primary drive, the main contacts being responsive to the opening spring. In response to the first control signal, the primary drive moves to charge the opening spring, and in response to the second control signal and the main contacts being closed, the primary drive moves to allow the opening spring to discharge thereby resulting in the main contacts opening independent of the motor.
