A circuit protection device (122) includes a trip mechanism (128) and at least one capacitor (140) configured to store electrical energy and to provide the electrical energy to the trip mechanism (128). The circuit protection device (122) also includes a controller (126) communicatively coupled to the at least one capacitor (140) and configured to measure a charge property of the at least one capacitor (140), compare the measured charge property to a threshold, and output a signal indicative of the comparison. |
