1. A smart accessory device for use with a circuit breaker, the circuit breaker including an operating mechanism and actuating components structured to actuate the operating mechanism, the smart accessory device being separate from the actuating components and operating mechanism and being structured to be operatively coupled to the circuit breaker so as to be able to actuate the operating mechanism, the accessory device comprising:
a power section structured to be electrically connected to a power source, the power section comprising:
an actuator structured to actuate the operating mechanism of the circuit breaker;
a current sensor structured to sense a current provided by the power source to the accessory device; and
a voltage sensor structured to sense a voltage provided by the power source to the accessory device; and
a control section electrically and operatively connected to the power section, the control section comprising a processor,
wherein the power section and the control section are not components of the operating mechanism,
wherein the processor is configured to monitor a power provided by the power source to the accessory device based on information received from the current sensor and based on information received from the voltage sensor,
wherein the processor is configured to determine whether the power provided by the power source to the accessory device is sufficient to enable the accessory device to actuate the operating mechanism of the circuit breaker.
