The utility model relates to a rail vehicle is DC600V overtemperature prote ware for electric heater, the constitution includes: high temperature resistant inner bag has been placed to high temperature resistant shell, fuse, power supply lead wire in the high temperature resistant shell, in this high temperature resistant inner bag was arranged in to the fuse, the power supply lead wire penetrates behind high temperature resistant shell and the high temperature resistant inner bag to be connected with the power line ball copperhead at fuse both ends, and it has sealing silica gel to fill between high temperature resistant inner bag and the high temperature resistant shell. Owing to very easily explode behind the overtemperature prote ware ceramic package chance water and split, can lead to the overtemperature prote ware short circuit phenomenon to appear. The utility model discloses on former direct current DC600V overtemperature prote ware basis, increase high temperature resistant shell. The arc phenomenon
