Abstract
A circuit breaker configured to be remotely operated by a controller is disclosed. The circuit breaker includes a set of main contacts, an operating mechanism, a remotely operable drive system configured to open and close the main contacts separate from actuation of the operating mechanism, and a control circuit in operable communication with the main contacts. The drive system includes a motor, and a primary drive responsive to the motor and in operable communication to open and close the main contacts. 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.
