Circuit interrupter including indicator circuit

摘要

A circuit interrupter includes an enclosure; a first terminal; a second terminal; separable contacts electrically connected between the first and second terminals; an operating mechanism structured to open and close the separable contacts; and an indicator circuit electrically interconnected with the second terminal The indicator circuit is structured to indicate occurrence of a signal at the second terminal. The signal has a frequency substantially greater than a power line frequency.
