1. A switching-condition-indicating status indicator for a circuit breaker operable automatically upon overload to a tripped switching condition and including breaker terminals adapted for connection to electrical power lines so as to interrupt the flow of electrical power to an associated load upon tripping of said breaker, said breaker including an actuator handle for resetting said breaker to a closed switching condition and thereafter between open and closed switching conditions, comprising:

  • detecting means for detecting all of said switching conditions of said breaker; and

    light emitting display means powered from said breaker terminals and responsive to said detecting means for providing three different display conditions visually indicating the switching condition of said breaker, said display means includes first and second light-emitting diodes producing different first and second output colors, only said first light-emitting diode being energizable when said breaker is in one of said breaker switching conditions, only said second light-emitting diode being energizable when said breaker is in another of said breaker switching conditions, and both of said light-emitting diodes being energizable when said breaker is in the remaining breaker switching conditions to provide first, second and third display conditions.
