End of life monitoring for a solid-state circuit breaker

A method of end-of-life monitoring for a solid-state circuit breaker, the method comprising:

• providing an air gap and a semiconductor switching device disposed in series between an input electrical conductor and an output electrical conductor;
• through operation of a microprocessor:
• retrieving health data and counter data or timer data from a memory, wherein the health data comprises data corresponding to monitored parameters associated with operational use of the solid-state circuit breaker,
• determining a status of a health rating of the solid-state circuit breaker being based on the health data, and the counter data or the timer data by comparing the health rating to a threshold,
• wherein the health rating is based on the following:
• amount of time of operation, amount of time of conducting current over a predetermined amplitude, amount of time of operating with a temperature over a predetermined value, number of overload trips, number of high interrupting capacity (HIC) trips, and number of mechanical operations of the air gap,
• in response to the status of the health rating being below a predetermined value, sending a message indicating the health rating is below the predetermined value using a radio to an end user via a smart phone application (APP) and start the counter or timer to track a grace period,
• determining whether the counter has reached a predefined value or the timer has reached a predetermined duration,
• in response to the counter having reached the predefined value or the timer having reached the predetermined duration, turning the solid-state circuit breaker off and inhibiting from being turned on,
• sending a solid-state circuit breaker OFF/disabled alert message using the radio to the end user via the smart phone application (APP), and
• in response to the counter not having reached the predefined value or the timer not having reached the predetermined duration, incrementing or decrementing the counter or the timer.
