Eaton Specification Sheet - NPL400400SA
Material and weight: Aluminum construction delivers corrosion resistance while remaining lightweight, enabling faster handling and reduced installer fatigue on long runs in control panels and electrical rooms. This translates into measurable productivity gains and lower labor costs on every project. Application: ideal for aluminum conduit nipples in rigid/IMC applications where frequent assembly and disassembly occur. Dimensional fit and compatibility: The 4 in length with a 4x4 footprint aligns with standard 4x4 enclosures and common rigid/IMC conduit layouts, reducing the need for adapters and field modification. Application: streamlines panel wiring in automation deployments and minimizes space conflicts in crowded control cabinets. Compliance and safety: NEC/CEC compliance and Ordinary/Non-Hazardous Location classification support code-conforming installations across North American facilities. This provides engineering teams with clear regulatory alignment and easier approvals. Application: suitable for typical manufacturing floors, data centers, and process plants. Installation efficiency and documentation: The availability of Eaton’s spec sheet for NPL400400SA aids field teams with exact installation guidance, reducing rework and warranty issues. Application: accelerates project timelines and supports standardized equipment catalogs. Durability and lifecycle: Aluminum construction withstands industrial environments, while the lightweight form factor aids ergonomic handling and reduces fatigue during long conduit runs. Application: reliable conduit connections in harsh environments, with predictable performance over the lifecycle of automation projects.
