SSCB is a special circuit breaker that uses thyristor devices as breaking elements. Compared with the traditional circuit breaker mechanical structure to realize the breaking function, SSCB has the following characteristics:

1. Greatly improve the breaking speed, reaching the microsecond level, and improve the stability of the system;

2. Accurately control the switching time;

3. Long operating life, not limited by the number of switches;

4. It can limit the fault current；

5. There is no contact mechanism and arc extinguishing chamber to reduce the failure rate;

6. No noise, Maintenance-free.
