1. An electronic circuit breaker, comprising:

  • a microcontroller that receives power derived from a line current that passes through the circuit breaker when the circuit breaker is in an on state;

    a trip mechanism that trips the circuit breaker in response to detection of at least one fault condition on a line to which the circuit breaker is connected;

    a trip solenoid that causes the trip mechanism to trip the circuit breaker in response to receiving a trip signal from the microcontroller; and

    a bi-stable display electrically coupled to the microcontroller, the microcontroller being programmed to modify the bi-stable display when the trip signal is sent to the trip solenoid, wherein the bi-stable display shows a fault-type indication indicative of one of a plurality of fault types causing the circuit breaker to trip and continues to display the fault-type indication after the circuit breaker has tripped.
