The PCRH 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 PCRH adds to the technology offering found in our PCR by featuring an explosion-proof package making it suitable for use in Class 1, Division 1 and Zone 1 areas. The PCRH’s third party certifications for Division 1 and Zone 1 areas make it the first decoupler in the world to carry such certifications.
