A DC circuit breaker system includes a first mechanical switch, a first parallel capacitor connecting a first terminal and a second terminal of the first mechanical switch, a second mechanical switch in series with the first mechanical switch, a second parallel capacitor connecting a first terminal and a second terminal of the second mechanical switch, a first diode connecting the first terminal and the second terminal; and a second diode connecting the first terminal and the second terminal. The first mechanical switch separates contacts in response to a fault current; the second mechanical switch separates contacts in response to the fault current; and opening the first and second mechanical switches and turning off the first and second diodes reverses current flow and clears a current fault. The DC circuit breaker system may also be equipped with a surge arrestor at its input and a freewheeling diode at its output.
