Eaton Specification Sheet - PLG55 SA
Copper-free aluminum construction delivers reliable corrosion resistance in aggressive atmospheres while keeping weight low, reducing handling strain and installation time. This translates to measurable maintenance savings and faster project throughput on new builds or retrofits in hazardous locations. The 1-1/2" trade size aligns with common industrial conduit schematics, minimizing the need for adapters and simplifying field assemblies. Rigid/IMC compatibility ensures a secure, vibration-resistant seal in demanding environments, extending service life in equipment rooms and outdoor installations. The square-head configuration enables faster tool engagement with standard wrenches, improving on-site productivity and reducing torque-related stripping risks. NEC/CEC compliance and explicit Class I, Division 1/2 and Class II/III ratings provide regulatory certainty, supporting safer commissioning and easier audits. Documentation and available catalog pages help buyers compare this plug against competing fittings, ensuring correct selection for new builds and refurbishments. With a compact 1.9 in length and height, and a 1.66 in width, the PLG55 SA fits tight conduit arrays without compromising sealing integrity. The 0.3 lb weight contributes to easier handling during installation and inventory planning for field crews. Overall, the PLG55 SA delivers a proven combination of material performance, certified safety, and installation efficiency that supports reduced downtime and improved project ROI.

FAQs
To install the PLG55 SA, align the plug with the conduit entry, insert into the enclosure opening, and tighten using a standard square-head driver until the seal is snug. The copper-free aluminum body resists corrosion, while the 1-1/2" trade size matches common rigid/IMC fittings, minimizing the need for adapters. Ensure proper torque per your project standards and verify that the enclosure remains rated for Hazardous/Classified Locations after installation.
The PLG55 SA carries NEC/CEC standards and is rated for Class I, Division 1 and Class II, Division 1/2, Class III environments. Its area classification and copper-free aluminum construction are designed to meet stringent industry requirements, making it suitable for use in hazardous locations while simplifying regulatory audits and approvals.
Yes. The PLG55 SA is specified forRigid/IMC conduit and uses a 1-1/2" trade size, aligning with standard catalog fittings. Its square-head design facilitates rapid tightening with common tools, reducing installation time and maintaining a consistent seal across a fleet of enclosures and panels in wire management systems.
Copper-free aluminum offers excellent corrosion resistance in harsh environments while keeping weight low, which reduces handling effort and strain during installation. This material choice enhances long-term durability in corrosive atmospheres typical of chemical plants, offshore facilities, and other hazardous settings, helping lower maintenance costs over the life of the installation.
By delivering compliant, quick-install sealing in hazardous locations, the PLG55 SA lowers commissioning time and minimizes downtime due to ingress or leaks. Its durable aluminum construction reduces replacement frequency, while standard-conduit compatibility decreases spare parts requirements. Collectively, these factors translate to shorter project cycles and measurable ROI for upgrade projects and new builds.
