摘要： An insulating substrate has a heat generating resistor and an electrical conductor on its surface. A pair of conductors, such as power or communication leads, are connected to a protected circuit. A rated voltage element and the heat generating resistor is connected in series between the lines. The electrical conductor is connected in series between one of the lines and the protected circuit. When a continuous overvoltage greater than a rated voltage of the rated voltage element develops in the lines, the rated voltage element acts to draw excess current through it and the heat generating resistor. When this current reaches a certain point, heat from the overcurrent in the heat generating resistor ruptures the substrate and the electrical conductor so that both the rated voltage element and the circuit are isolated from the conductors. This protects the protected circuit from destruction of, and consequent loss of protection by, the rated voltage element. It also protects the rated voltage element itself by isolating it from the overvoltage.

摘要： 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.
