PROBLEM TO BE SOLVED: To provide a current distribution device which performs normal interruption operation upon occurrence of short circuit, in a power supply system combining a fuse PDF and an MCCB-PDF.SOLUTION: The current distribution device includes a first current distribution circuit using an MCCB as an interrupter, and a second current distribution circuit using a fuse as an interrupter. The first current distribution circuit and the second current distribution circuit are connected with the same power supply. In the second current distribution circuit, one end of a capacitor is connected to the power supply side of the fuse, and a diode for interrupting a current, flowing toward the first current distribution circuit, is connected between the branch point of the first and second current distribution circuits and the capacitor. |
