Eaton Specification Sheet - NPL50500SA
Feature → Business Impact → Application: The NPL50500SA is made from aluminum, delivering corrosion resistance and a lower weight than steel alternatives, which reduces handling risk during installation and lowers labor costs on site in busy panel shops. This translates into faster onboarding for new installations and longer service life in harsh environments where exposure to moisture and chemicals is common. Application-wise, it suits 1/2" rigid/IMC conduit runs in industrial controls and switchgear, where dependable grounding and enclosure integrity matter. Feature → Compatibility → Application: Designed for Rigid/IMC conduit and 1/2" sizing, it integrates seamlessly with existing Eaton Crouse-Hinds components, simplifying inventory and improving install speed for panel builders. This compatibility reduces mismatch errors and minimizes rework during panel upgrades or new builds. Feature → Compliance → Application: NEC/CEC compliance plus UL certification provide a clear path to regulatory adherence and safe operation in Ordinary/Non-Hazardous Locations, which is critical for facilities targeting uptime and risk mitigation. Feature → Practicality → Application: The 5" length and compact dimensions enable fewer fittings and neater installations, especially in tight electrical closets or equipment enclosures, delivering cost savings through reduced part counts and faster assembly. Feature → Industry Insight → Application: Aluminum conduit nipples like NPL50500SA are increasingly preferred in lightweight, corrosion-resistant installations common in chemical processing, water treatment, and data centers, supporting sustainable, maintenance-friendly wiring strategies.
