Dairyland Electrical Industries Polarization Cell Replacement - PCR & PCRH

Dairyland Electrical Industries Polarization Cell Replacement - PCR & PCRH

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 has very 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, making it the most ideal isolation and grounding product for cathodically protected structures. In addition to out-performing polarization cells, the PCR also surpasses metal oxide varistors and gapped arresters, clamping lightning-caused over-voltages to the lowest possible levels.

Features and Characteristics

  • Range of AC Fault Ratings
  • Higher Blocking Voltage than Polarization Cells
  • UL and C-UL Listed for Grounding Electrical Equipment
  • UL, C-UL Listed for Class I, Division 2 Locations
  • Certified by UL/Demko for Meeting ATEX Directive for Zone 2; CE Marked
  • Available in Submersible Version

DEI offers two versions of the PCR for addressing hazardous (classified) locations: the standard PCR for Class I, Div 2 and Zone 2 areas, and the PCRH for Class I, Div 1 & 2 areas. Having been fully tested and listed by Underwriter's Laboratory (UL) to the US and Canadian standards, the device carries the UL mark and C-UL (Canada) mark. No other known company offers decouplers with third-party listings for hazardous locations.

Features and Characteristics

• UL, C-UL listed explosion-proof design: unique to the industry
• Uses the same solid-state internal construction as our industry standard PCR
• Listed for use in Division 1 & 2 areas, Groups C, D
• Listed as an "effective grounding path" per the NEC and CSA grounding standards
• Offered with optional customized lead kits
