    摘要： The present invention relates to the technical field of surge protective devices, and specifically discloses an SPD plug-in module, an SPD base and a plug-in SPD. The SPD plug-in module includes a rectangular outer shell and an internal assembly. The rectangular outer shell is provided with a first plugging locking structure, a first guiding plugging structure, a window, an internal assembly clasping structure and a mis-installation-proof structure, etc., which are easy for plugging as well as for fixing the internal assembly. The internal assembly can be in a multi-chip tripping structure, such as an interruption turnable, which has a wide range of applications. The rectangular outer shell and an inner shell of the internal assembly are integrally formed, so that the product is simple and pretty, easy to assemble, and has a reliable structure, and costs are effectively controlled. The SPD base adopts upper and lower bottom shells formed integrally, which divide the internal space into multiple preset spaces, and wiring assemblies, alarm components, etc. are disposed in the respective spaces. The upper and lower bottom shells can be closed to complete assembly. The assembly process is convenient and the structure is firm. The plug-in SPD is composed of the SPD plug-in module and the SPD base, and can be widely used for AC/DC surge protection of low voltage systems below 2000V.
