Abstract
A surge protection device with an internal circuitry that protects a premise device from a surge input that arises from a transient event, e.g., a lightning strike. The internal circuitry can comprise a surge path that includes windings, e.g., inductors, and in one embodiment the surge path comprises a first winding and a second winding that is coupled in series to the first winding. The internal circuitry can also comprise a blocking element that is positioned relative to the surge path so that the blocking element receives the surge input before the premise device, wherein the blocking element can be selected so as to isolate the premise device from the surge input.
