    Abstract: An electronic trip unit which includes a processing unit and a comparator circuit. The processing unit receives an input voltage, and a reset signal to reset the electronic trip unit, and generates a trip signal when sensed current of the electronic trip unit exceeds a predetermined threshold. The comparator circuit includes a first comparator which receives the trip signal from the processing unit and compares the trip signal with a predetermined reference voltage determined based on the reset signal, and a second comparator which compares a voltage generated by a power supply with the predetermined reference voltage. The comparator circuit determines whether the trip signal is for a valid trip event based comparison results of the first comparator and the second comparator.

The system includes a transistor electrically coupled to a controllable variable resistor having a predetermined resistance. The transistor applies a test voltage signal to the circuit indicative of a first temperature value. An amplitude of the test voltage value is indicative of a simulated thermistor temperature value. The microprocessor determines a test temperature value based on the amplitude of an output voltage of the circuit. The microprocessor also determines an inaccuracy value based on the test temperature value and the simulated thermistor temperature value.

    Abstract: A circuit breaker configured to be remotely operated is disclosed. The circuit breaker includes a set of main contacts configured to connect between an electrical source and an electrical load, an operating mechanism in operable communication to open and close the main contacts, and a remotely operable drive system configured to open and close the main contacts separate from actuation of the operating mechanism. The drive system includes a motor responsive to first and second control signals, a primary drive responsive to the motor, and an opening spring responsive to the primary drive, the main contacts being responsive to the opening spring. In response to the first control signal, the primary drive moves to charge the opening spring, and in response to the second control signal and the main contacts being closed, the primary drive moves to allow the opening spring to discharge thereby resulting in the main contacts opening independent of the motor.
