ABSTRACT:
A circuit breaker assembly incorporating a light emitting diode as an indicator when an overload condition is present and the circuit has been blown and further wherein the assembly includes an integral, internally placed load in the form of a capacitance sufficient to energize the light emitting diode when the load normally present in the circuit has been removed. The capacitance is connected in series with the light emitting diode as well as an external ground contact for providing the ground return for energizing the light emitting diode.
