To provide an automatic restoration device of an outlet circuit capable of automatically restoring the outlet circuit only by turning off a power source of an unnecessary load when the outlet circuit is shut off, and of preventing the power source of a necessary load from being turned off without shutting off a main breaker or a branch breaker by overload or without needing complicated operation or setting.

A flowing current of outlet circuits 2 and 3 is detected by a current transformer 5 to compare a current value outputted from an overload detection circuit 6 with a preset current upper limit value by a comparison circuit 7; when the detected current value exceeds the current upper limit value, a signal is outputted from the comparison circuit 7 to a thyristor drive circuit 8; and a relay 11 is driven by a relay drive circuit 9 by using the output of the drive circuit 8 to shut off the outlet circuit 3 with a fluctuating load connected. While the outlet circuit 3 is shut off, the power source of the load is manually turned off to reduce a use power amount, and when a certain period elapses, the relay 11 is turned off to restore the outlet circuit 3.
