Abstract: A method of open-loop fault control of a solid state circuit breaker includes the steps of populating a lookup table with predetermined current and temperature values and corresponding interrupt times, measuring a temperature of the solid state circuit breaker, measuring an electrical current passing through the solid state circuit breaker, estimating interrupt time from the lookup table based on the measured temperature and current values, determining to initiate a shutoff of the solid state circuit breaker based on the estimated interrupt time, and initiating a shutoff process of the solid state circuit breaker.
