A special protection device for a surge protection device capable of tolerating large current relates to an input terminal connected with an input connecting piece, the input connecting piece is connected with a moving contact mechanism through a flexible lead cluster, the moving contact mechanism is movably connected with an input end of a discharge tube through a static contact, and the moving contact mechanism is controlled by a linkage mechanism. The linkage mechanism is connected with a wrench at the top of the device; the discharge tube is connected with the trip coil module in parallel, and the output end of the discharge tube is connected with the wiring end of the trip coil module through the resistor and further connected with the output terminal of the device. The current impact resistance of the device can be greatly improved, good welding spot and device structures can still be kept after multiple times of current impact, the structural design is compact and reasonable, and the performance is sta
