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 & 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.

Comparison of Dairyland PCRH to other solid-state devices
Following on the success of the model PCR, the Dairyland model PCRH offeres fully certified products for Class I, Division 1 hazardous locations. There are no equivalents to the model PCRH; however it is common for others to place a protection product inside of a commercially available explosion-proof box and erroneously consider the entire package to be considered "explosion-proof." Altering a certified enclosure nullifies the listing or certification unless the entire package is again tested and recertified. Dairyland has taken the route of full testing and certification for the model PCRH, as it is used in explosive atmospheres. The device was successfully tested and certified.
The PCRH has extensive certification. In fact, no other products of this type on the market have any known certification to any standards whatsoever. Consider the following PCRH certifications:
UL listed as an "effective grounding path" per the US National Electrical Code (NEC).
UL listed for blocking cathodic protection current per the US NEC.
UL listed as meeting the lightning surge current standards.
UL listed for Class I, Division 1 & 2 hazardous locations.
UL listed NEMA 4 environmental rating.
C-UL listed as an "effective grounding path" per the Canadian Electrical Code.
C-UL listed for Class I, Division 1 & 2 hazardous locations.
Other features include:
Unique, patented construction that assures maintenance-free operation.
Assured fail-safe design, independently tested.
Proprietary manufacturing methods that assure corrosion resistance, high AC fault capability, and low leakage current.
