The control component is arranged on the upper part of the cabinet, and the leakage protection component is arranged on the left side of the control component. The rear side of the leakage protection component is connected to the mounting rail. The distribution switch control device with a leakage protection structure is provided with a connection block on the rear side of the control panel, and the control panel is installed in the mounting rail through the connection block for buckling to facilitate installation and disassembly. A power-off unit is provided inside the protector body, and a communication module is provided inside, which can detect power fluctuations in real time.
