A series surge suppression structure mainly comprises: a circuit board, a ground line and a plurality of galvanization circuits being disposed thereon, a multilayer surge absorption unit being disposed in series on the ground line and the plurality of galvanization circuits; wherein each surge absorption unit is constituted by a pair of chokes with a layered surge absorption element connected in parallel between one end of either choke and the ground line; a power connection terminal, positioned on one side of the circuit board and electrically connected to a final end of the multilayer surge absorption unit; and a protection terminal, positioned on another side of the circuit board and electrically connected to a final end at another side of the multilayer surge absorption unit; whereby, the protection terminal can be used to connect with a communication circuit or an electric facility and the power connection terminal is used for connecting with an external wire so as to form a multilayer surge absorption protection by means of series connection. Meanwhile, a derivative module may be conveniently manufactured to allow multiple modules to be connected together and expand to use as a three-phase multilayer surge absorption protection thereby expanding a use range to attain to the surge substantially suppressing effect.
