The invention relates to the field of anti-thunder, in particular to a current control assembly. False operation can be overcome in a whole course thunder surge voltage range. The current control assembly comprises a tripping mechanism, a moving contact, a fixed contact, discharging gaps, a negative temperature coefficient resistor and an electromagnet, wherein the electromagnet comprises an electromagnet coil and a moving iron core; the electromagnet coil is connected with the negative temperature coefficient resistor in series; the discharging gaps are connected to two ends of the negative temperature coefficient resistor and the electromagnet coil in parallel; the tripping mechanism is in linkage with the moving contact; when the moving iron core moves, the moving iron core hits against the tripping mechanism; after tripping is completed by the tripping mechanism, a contact state of the moving contact and the fixed contact changes to a separation state. The false operation of the electromagnet can be solved, the working of circuits is normal, lightning currents are communicated, power frequency currents are cut off, and therefore the circuits are protected.
