ABSTRACT:
A current limiting device utilizes an electrically conductive composite material and an inhomogeneous distribution of resistance structure. The current limiting device has a conducting filler and at least two electrodes, where at least one of the electrodes comprises a grooved electrode structure. The grooved electrode structure maintains contact between the electrodes and the composite material, even with consumption of the composite material and production of residue during a high current condition.
