A leakage detection breaker includes a current transformer configured to detect a leakage current, and a leakage determination unit configured to determine DC and AC leakages based on an output signal from the current transformer. The leakage detection breaker further includes a power supply cut-off unit configured to cut off a supply of DC or AC power when the current leakage determination unit determines the occurrence of the DC or AC leakage.
