Abstract
A circuit breaker closing actuator and a method of operation is provided. The closing actuator is disposed to communicate and receive signals from a trip unit. The trip unit includes a communications to transmit and receive data and signals from a remote location. The trip unit transmits a signal to the closing actuator in response to receiving a closing signal from the remote location. The closing actuator validates the signal and activates a driving circuit if the signal is validated. The driving circuit enables power to a solenoid that closes the circuit breaker.
