The PCR is a solid-state device designed to simultaneously provide DC decoupling and AC continuity/grounding when used with cathodically protected structures, such as pipelines, tanks, grounding systems, and cable casings.

The PCR is an ideal replacement for electrochemical polarization cells.
In a compact, solid-state package, the PCR has high AC fault current and lightning surge current ratings.
With a higher blocking voltage than polarization cells, the PCR eliminates the need for placing devices in series.
It also outperforms any metal oxide varistor or gapped arrester, clamping lightning-caused over-voltages to the lowest possible levels.
