Abstract:
A Basic Surge Protector comprising a line side and a load side, for protecting an electrical or an electronic equipment connected to said load side of the Surge Protector, from spurious or excessive transient voltages or surges or both on said line side of the Surge Protector, that are above a predetermined value, on said line side of the Surge Protector, the Surge Protector further comprising:(a) at least one switch means series mounted between said line side and said equipment on said load side, wherein said switch means is responsive to a signal that allows or interrupts a flow of current through said switch means, to said equipment on said load side of the Surge Protector, thus isolating said equipment from the transients and surges on said line side of the Surge Protector;(b) at least one fuse means or a current responsive means connected to a hot or a positive line of said line side of the Surge Protector and a threshold point, wherein said fuse means or said current responsive means responds to a fault condition that exceeds said predetermined value, due to a surge voltage or current into at least one over voltage detection or suppression means connected across said threshold point and a earth ground or across said threshold point and a return line or a neutral line on said line side of the Surge Protector,(c) wherein said threshold point is further connected to said switch means, and disables said switch means, thus disabling the flow of current flowing through said switch means to said equipment on said load side, when said fuse means or said current responsive means blows or disengages for a predetermined period, due to said surge voltage or current exceeding said predetermined value.
