Eaton Specification Sheet - PLG85
Gray iron alloy housing delivers rugged protection against impact and corrosion, ensuring long service life in demanding installations. This material choice translates to reduced maintenance costs and fewer field repairs, particularly in chemical processing plants and refinery environments where abrasion and exposure are common. The square-head configuration enables tool-friendly, consistent torque during assembly, speeding up panel and enclosure work and improving operator safety in tight spaces. It reduces installation time and provides reliable seating, even in restricted mounting areas. Certified for Hazardous/Classified Locations with NEC/CEC compliance and UL certification, the PLG85 helps meet regulatory requirements and supports risk management for oil, gas, mining, and chemical facilities. The 3" trade size matches standard conduit fittings, simplifying inventory and enabling straightforward integration with existing control systems. Comprehensive specifications and UL documentation streamline design reviews and accelerate procurement, delivering predictable lead times for projects and maintenance cycles.

FAQs
Begin by verifying the area classification and ensuring all safety requirements for Hazardous Locations are met. Insert the PLG85 into the conduit opening, align the square-head with your tooling, and tighten to a secure seat without over-torquing. Confirm the enclosure is fully sealed and the plug sits flush to the enclosure surface before energizing equipment. Refer to the Eaton PLG85 specification sheet for torque guidelines and re-check after thermal cycling events.
The PLG85 is designed for Hazardous/Classified Locations and carries NEC/CEC compliance with Class I, Division 1 and 2; Class II, Division 1 and 2; and Class III ratings, supporting safe operation in oil, gas, mining, and chemical processing environments. UL certification is available for additional verification in hazardous location applications.
Yes. The PLG85 is supported by UL certification documentation for use in Hazardous Locations, and UL reports for Canada and the US are available through Eaton’s resources. This certification helps validate compliance during regulatory audits and customer approvals.
The PLG85 has a 3" trade size with a gray iron alloy body. It measures approximately 3.5 inches in depth and height, with a width of about 2.26 inches, and weighs roughly 1.75 pounds. It is intended for rigid/IMC conduit installations in demanding environments.
PLG85 is ideal for control panels, junction enclosures, and field installations in hazardous locations such as chemical plants, refineries, and mining operations where NEC/CEC compliance and robust mechanical sealing are required. Its square-head design and 3" trade size enable quick, repeatable installations with reliable performance over time.
