  • Electronic status reporting circuit breaker
    Patent number: 10651681
    Abstract: A circuit breaker includes a control circuit capable of generating and transmitting a test pulse through its attached circuit and any connected load while its contacts are open, with the breaker in the OFF, or TRIPPED, state, to determine if detrimental anomalies exist, such as a short circuit. In certain configurations, the control circuit can measure and store a circuit's parameters for a properly operating load when the breaker is in the OFF state, and subsequently with the breaker in the OFF, or TRIPPED, state, compare the stored parameters to determine if an alarm condition exists and thereby initiate appropriate alerts and actions. In an alternate configuration, the breaker can be commanded to the OFF position by the load sending a signal through the power connection, with the breaker then being able to store the load's reason for shut-down and report such information to a remote location.
