Abstract: The present invention relates to a solid state circuit breaker. A current sensor detects the occurrence of overcurrent according to the change in the magnitude of the current flowing into the semiconductor circuit breaker, transmits a signal notifying the occurrence of overcurrent to a control unit of a semiconductor circuit breaker, and determines whether the overcurrent is a noise overcurrent or a fault current based on an integral value obtained by integrating the magnitude of the current detected according to the time elapsed after the occurrence of the overcurrent. A semiconductor circuit breaker including the current sensor limits the amount of current that can be output from the semiconductor switch unit by limiting the gate voltage applied to the gate terminal of each semiconductor switch when an overcurrent occurs, and depending on the type of overcurrent determined by the current sensor, the gate drivers of each semiconductor switch are controlled so that the load and the semiconductor circuit breaker are cut off from the power system or the limited gate voltage is restored.
