Abstract:
A system for sensing and indicating an overcurrent condition in an electrical circuitry, comprising:a trip unit configured to sense the overcurrent condition; a module coupled to the trip unit and configured to selectively control power to the trip unit in response to an indication signal transmitted from the trip unit, wherein selectively controlling the power to the trip unit permits communication of a data corresponding to the overcurrent condition and permits configuring the trip unit to sense a subsequent overcurrent condition, wherein the module includes a first controller configured to continue power to the trip unit for a first length of time after the overcurrent condition has been sensed by the trip unit; and a second controller configured to reset the trip unit after the data has been communicated, wherein the second controller is a monostable multivibrator and the trip unit is reset by toggling the power to the trip unit â€œoffâ€  for a second length of time and then â€œon.â€
