Abstract
A circuit breaker includes a line phase terminal, a load phase terminal, a line neutral terminal, a conductive path formed between the line phase terminal and the load phase terminal, the conductive path having an open configuration and closed configuration, a sensor, a linkage configured to move the conductive path between the open configuration and the closed configuration, a rocker selectively engageable with the linkage, the rocker configured to move the linkage between an open position and a closed position, and an arm selectively engageable with the rocker, the arm to prevent the conductive path from moving to the closed configuration unless the circuit breaker passes a self-test when movement of the rocker is detected. A trip operation of the circuit breaker includes a time delay based upon an amount of current on the conductive path detected by the sensor.
