This model utility discloses a surge protective device and comprises: the first voltage threshold protective component, the first disengaging device, the second voltage threshold protective component, a discharging tube, a current limiting resistor and quick voltage threshold protective components, wherein the first voltage threshold protective component, the first disengaging device and the second voltage threshold protective component is connected in series orderly, the other end of the first voltage threshold component is out of the phase leads and the other end of the second voltage threshold protective component is out of the neutral end; the end introduced between the first disengaging devices and the second one is connected in parallel with the discharging tube and the branch circuit comprising current limiting resistor and the quick voltage threshold protective component while the grounding terminal is between the said discharging tube and the other end of the branch circuit the phase end and neutral wire end constitutes lead neutral protection mode; the phase end and grounding end constitutes lead grounding protection mode; neutral end and ground end constitutes neutral grounding protection mode. The technical program adopting this model utility provides a multi protection modes, little limiting voltage and quick responding surge protection device while provide a disengaging device further reflecting the true temperature.
