Patent ID: 7019606

Claim:
A circuit breaker configured to be remotely operated by a controller, the circuit breaker comprising: 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; a remotely operable drive system configured to open and close the main contacts separate from actuation of the operating mechanism, the drive system comprising a motor responsive to first and second control signals, and a primary drive responsive to the motor and in operable communication to open and close the main contacts; and a control circuit in operable communication with the main contacts; wherein the control circuit has a first impedance in response to the main contacts being closed and a second different impedance in response to the main contacts being open; and wherein the control circuit indicates a closed main contact state in response to the operating mechanism being in an on position and the main contacts being closed, and an open main contact state in response to the operating mechanism being in an on position and the main contacts being held open via the drive system.
