The invention provides a current terminal capable of reflecting the operation state of a current loop. The current terminal comprises a terminal buckle and an insulating plate. The terminal buckle has a clamp groove slot, one side, far from the clamp groove of the terminal buckle is a flat end, the insulating plate is internally provided with two insulating vertical plates in parallel, and one ends of the insulating vertical plates are connected with the flat end. An insulating channel is formed between the two insulating vertical plates. The two insulating vertical plates are internally provided with an abdicating groove respectively. The current terminal also comprises two conductive isolation plates, and one ends of the conductive isolation plates enter the insulating channel through the abdicating grooves. Parts entering the insulating channel of the conductive isolation plates have a first penetrating screw hole respectively. Parts far from the insulating channel of the conductive isolation plates have a second penetrating screw hole respectively. The current terminal also comprises an LED warning device which is arranged in the insulating channel and located between the two first penetrating screw holes. When isolation plate screws enter the two first penetrating screw holes, the LED warning device is electrically connected with the isolation plate screws and then is lightened.
