ABSTRACT:
A three-condition constantly illuminated status indicator is provided in a circuit breaker to provide three luminesce displays indicating that the breaker is in the on, off or tripped condition. Associated electrical circuitry employs diode-steered capacitive charging elements for selective, common or simultaneous energization of a three-color light emitting diode display without acting as a bypass around the circuit breaker, thus eliminating shock hazard. Selective energization of the light emitting elements is achieved by auxiliary switching means operable to a plurality of switching conditions according to switching conditions of the circuit breaker. The capacitors serve as an impedance to current for the light emitting diodes, eliminating the need for ballasting resistors, resulting in a cooler operating, lower power consumption unit.
