ABSTRACT:
A surge suppressing device includes a voltage-dependent resistor having an opening formed therethrough. A pair of preformed pads formed of an electrically conductive material is located adjacent a first and second side respectively of the voltage-dependent resistor proximate the opening. The electrically conductive material flows through the opening creating an electrical short between the first and second sides when the voltage-dependent resistor is heated in response to excessive leakage current flowing therethrough.
