DC circuit breaker mainly has the following functions:
| Function | Description |
| Interrupt Direct Current | Designed to safely interrupt direct current (DC) flow in electrical circuits to protect against overloads and short circuits. |
| Arc Suppression | Utilizes various mechanisms such as magnetic fields and auxiliary capacitors to suppress arcs generated during the breaking process. |
| Bidirectional Fault Current Interruption | Capable of interrupting fault currents in both directions, ensuring comprehensive protection in DC transmission lines. |
| Magnetic Field Application | Applies a magnetic field to the vicinity of the arc to control and extinguish it quickly, enhancing performance. |
| Simplified Structure | Incorporates filtering and surge-absorbing capacitors to simplify the overall structure and improve efficiency. |
| Self-Excited Commutation | Uses self-excited commutation techniques to enhance the speed and reliability of current interruption. |
