| description | An electrical switching apparatus includes a number of separable contacts, an operating mechanism structured to open and close the separable contacts, a number of sensors structured to sense at least current flowing through the separable contacts, and a processor structured to cooperate with the operating mechanism to open and close the separable contacts. The processor determines a fault from the sensed current flowing through the separable contacts. The processor further responsively opens the separable contacts if the sensed current associated with the fault is less than the interrupting rating of the electrical switching apparatus. The processor keeps the separable contacts closed and waits for another circuit interrupter to interrupt the fault if the sensed current associated with the fault is greater than the interrupting rating. |
