Abstract
An electronic controller, connected to a digital communication network, is responsive to commands from a master controller to control solenoid operated circuit breakers. The electronic controller also determines the status of all circuit breakers and reports back to the master controller to verify that the command from the master controller was executed and to provide historical data regarding the status of the circuit breakers. The electronic controller is synchronized to the same alternating current (AC) power source as the circuit breakers to control the operation of the respective circuit breakers to minimize electromagnetic interference (EMI) caused by the switching of the circuit breakers. The electronic controller further controls the operation of the circuit breakers to reduce the duty cycle of the power supply for the circuit breaker solenoids.
