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.

Abstract: An arc fault circuit interrupter detector circuit including a super regenerative high frequency receiver is described herein. In one exemplary, non-limiting embodiment, a current measure component determines that a current noise signal within a circuit breaker is occurring at a particular frequency of interest. The super regenerative high frequency receiver receives the current noise signal and, via an oscillator circuit, causes the signal to ramp to a quench voltage, dissipate, and repeat. A microcontroller in communication with the super regenerative high frequency receiver measures a time period of the oscillator circuit's oscillations, and determines an amplitude of the current noise signal based, at least in part, on the time period. If it is determined that the amplitude of the input current signal at the frequency of interest corresponds to an arc fault event, a trip signal is generated to trip the circuit, quenching the arc fault event.

The HF current section is structured to, for each of the frequency sub-bands, (i) detect a rise in energy of the frequency sub-band above a first predetermined threshold level for at least a certain amount of time and (ii) cause the associated output to indicate a rise in energy detection in response to detecting the rise in energy above the associated threshold level for at least the associated certain amount of time. The module includes a processing device structured to determine whether a DC arc fault has occurred based on the outputs from the LF and HF current and LF voltage sections.
