Abstract
A circuit interrupter includes separable contacts, a trip actuator structured to cause the separable contacts to trip open, a conductor structured to carry power through the circuit interrupter, a sensor having a forward bias voltage drop inversely proportional to temperature and being disposed proximate the conductor, an amplifier circuit electrically connected to the sensor and being structured to amplify the forward bias voltage drop of the sensor, and a comparator circuit structured to compare the amplified forward bias voltage drop with a predetermined reference voltage and to output a signal to the trip actuator when the amplified forward bias voltage drop is less than or equal to the predetermined reference voltage. The signal causes the trip actuator to cause the separable contacts to trip open.
