Abstract
The present invention is an electrical circuit protection device having a PTC element with a first common electrode affixed to a first surface of the PTC element and at least two second electrodes affixed to a second surface of the PTC element. The at least two second electrodes are physically separated from one another such that when the at least two second electrodes are connected to a source of electrical current, the current travels from the at least two second electrodes, respectively, through the PTC element, to the first common electrode.
