Eaton Specification Sheet - PLG4 SA
Feature: Copper-free aluminum construction reduces weight and eliminates galvanic corrosion in challenging environments. Benefit: Improves handling during installation and extends service life in harsh settings. Application: Suitable for outdoor or chemically aggressive locations where weight reduction is beneficial in panel and junction enclosures. Feature: Recessed design provides a flush surface for quick, snag-free terminations. Benefit: Simplifies installation in crowded panels and reduces rework from misaligned conduits. Application: Ideal for tight spaces and panel tops where protruding plugs can interfere with hardware or wiring harnesses. Feature: Rigid/IMC conduit compatibility with a 1-1/4" trade size. Benefit: Ensures a secure, code-compliant seal across common conduit systems, minimizing leak paths and ingress. Application: Standardized fitment for many industrial installations in hazardous zones. Feature: NEC/CEC compliance with Class I, Division 1 and 2; Class II Division 1 and 2; Class III ratings. Benefit: Improves regulatory confidence, reduces risk of nonconformance, and accelerates permit approvals. Application: Required for electrical installations in hazardous or classified locations. Feature: Compact dimensions (1.66 in length and height; 0.8 in width) with a light 0.12 lb weight. Benefit: Space-efficient fit in tight enclosures and easier handling during maintenance. Application: Panels with limited space where a small-footprint plug is advantageous. Feature: 1-1/4" trade size and copper-free aluminum construction support long-term reliability and corrosion resistance. Benefit: Lower maintenance costs and fewer part replacements over the system lifecycle. Application: Wiring terminations in demanding environments where durability matters.

FAQs
PLG4 SA is designed for rigid and IMC conduit with a 1-1/4 inch trade size. Its recessed, copper-free aluminum construction supports secure terminations in space-constrained enclosures, making it a reliable choice for standard hazardous-location wiring.
The PLG4 SA carries NEC/CEC standards and NEC hazardous ratings that cover Class I Division 1 and 2, Class II Division 1 and 2, and Class III. It is also supported by Canadian certification references for use in hazardous locations, helping ensure regulatory compliance.
The recessed design creates a flush surface, reducing snagging and easing panel layout. This facilitates faster assembly, minimizes interference with cables and accessories, and supports cleaner, more reliable terminations in crowded or compact electrical enclosures.
The PLG4 SA measures 1.66 in in length and height, with a width of 0.8 in and a weight of 0.12 lb. This compact footprint improves fitment in tight panels and reduces overall enclosure volume without compromising mechanical integrity or sealing performance.
Using PLG4 SA supports regulatory compliance, reduces installation time, and lowers lifecycle costs by minimizing part variety. Its corrosion resistance and lightweight design help reduce maintenance and replacement needs, delivering faster commissioning and lower total cost of ownership in hazardous-location projects.
