CONSTITUTION: A protective device includes a yoke filter(11), a filter box(21), and an input terminal(23), and a terminal cap(110). A microwave generator(12) is installed in the inside of the yoke filter. The filter box accommodates a choke(22) connected with the microwave generator and is installed at one side of the yoke filter. The input terminal is connected with the choke and is exposed to an outer side of the filter box. The terminal cap is used for sealing the input terminal.
