Abstract
This technology enables proper protection coordination in power supply systems connected to storage batteries. [Solution] A device used in a power supply system, comprising a current detection unit and a control unit, wherein the control unit transmits a control signal to a device having a current interruption function, instructing the interruption of the current based on a first setting value, when the direction of the current measured by the current detection unit is a first direction, and transmits a control signal to a device having a current interruption function, instructing the interruption of the current based on a second setting value, when the direction of the current measured by the current detection unit is a second direction.
