The electrical signal detection unit detects an electrical signal on a loop, and send the electrical signal to the control unit. The control unit generates a control signal, and send the control signal to the first execution unit. The contactor is connected to the loop. The first execution unit controls the contactor to be closed or opened, where when the contactor is closed, the loop is connected, and when the contactor is opened, the loop is disconnected. The protection unit detects a current value on the loop when the contactor is closed, where an opening instruction is sent to the second execution unit when the current value reaches a trip threshold. The second execution unit opens the contactor when receiving the opening instruction.
