Zusammenfassung: | The present invention relates to a semiconductor circuit breaker and, more specifically, to a semiconductor circuit breaker, in which a protection circuit is modularized and thus maintenance and repair can be easily done. According to an embodiment of the present invention, the semiconductor circuit breaker includes: a main circuit unit connected between a power source and a load and having a semiconductor switch; an outer box provided with the main circuit unit embedded therein and having a module accommodation unit outside thereof; and a protection module detachably accommodated in the module accommodation unit. According to the present invention, a protection circuit such as a snubber circuit is configured as a module detachable from an enclosure, which is advantageous for capacity change or maintenance.
