Beschreibung
Zusammenfassung:	A smart accessory device (1) includes an actuator (10) and is designed to be used to actuate an operating mechanism of a circuit breaker in order to either open or close the separable contacts of the circuit breaker. The accessory can be one of a shunt trip, spring release, or under voltage release device. The actuator includes a solenoid (11) and plunger (12). The accessory determines the operating condition of the actuator based on how much current flows through the coil when the power source (50) provides power to the accessory device, and continually executes a coil diagnostic to determine the operating condition of the coil while power is being provided to the accessory device. If the accessory fails to trip the circuit breaker when required, the accessory can determine whether the failure was due to either of the solenoid or the plunger.
