Abstract	There is no zero crossing of the current in DC power circuits. Thus unless you cut off the short-circuit current quickly, the electrical fire caused by electric arc or spark can occur. And after the initial fault breaking operation the long-duration sustained interruption without fault recovery may cause a lot of serious economic losses. Therefore this paper proposes a new DC SSCB that has quick reclosing and rebreaking capabilities, and thus can perform the operating duties of reclosing and rebreaking required by the industrial standards and regulations. The proposed DC SSCB can perform rapid breaking, thus the material costs of power facilities can be reduced as the rapid breaking of DC SSCB enables selecting lower specification devices and minimizing auxiliary SCR. Also it can perform the operating duty of reclosing and rebreaking even in the state that short circuit lasts on load side. The operating characteristics of the proposed SSCB are verified by simulations and experiments on short circuit fault.
