ABSTRACT:
A combined noise filter and surge absorber for electrical and electronic equipment. The surge absorber may be removed for replacement, maintenance or testing without requiring the removal of the noise filter. Thus the equipment in which the noise filter is installed can continue to operate without the loss of noise filtering. The removability of the surge absorber from the noise filter allows flexibility in the installation of the surge absorber, enabling the invention to be adapted to a variety of equipment. A separate surge absorber can also be attached to equipment having an existing noise filter by means of various adapter embodiments of the present invention. These embodiments adapt the connecting terminals of the surge absorber to various types of external terminals of the noise filter.
