**7. Conclusions**

A unidirectional low voltage SSCB design process was framed, and then constructed and tested, in this study. The assembled SSCB is a viable option for the protection of low-level sensitive equipment in a DC distribution system as the circuit can operate at 50 V/15 A of continuous current, without failure.

The fault clearing speed of the design is limited to an average of 47.53 μs by the speed of the ADC, which is 294.7 times faster than a fast operating AC counterpart.
