FAQs
Install the SPM100480D4R within a NEMA 4 enclosure, connect line and load terminals per Eaton wiring diagrams, and verify 480V delta (3W+G) configuration. Ensure the internal circuit breaker is in the correct position for upstream protection coordination, and follow UL 1449 guidelines during commissioning. Proper grounding and conduit connections are essential for optimal performance and safety.
100 kA per phase indicates the maximum surge current the SPD can safely divert per phase without compromising protection. This rating enhances protection for high-energy transients common to industrial environments, reducing the likelihood of insulation damage in components such as drives, PLCs, and contactors while maintaining fast response times.
Yes. The SPM100480D4R uses a NEMA 4 enclosure designed to withstand outdoor and damp environments, offering reliable protection against dust, water, and corrosion ingress. This makes it suitable for enclosure-mounted protection in plant yards, load centers, and exposed electrical rooms, provided installation standards are followed.
The SPM100480D4R is UL 1449 listed, ensuring compliance with recognized surge suppression standards and electrical safety requirements. This certification supports NEC/IEEE compliance, improves QA traceability, and gives engineers confidence in system-wide protection coordination and reliability across industrial applications.
Maintenance for the SPM100480D4R is typically minimal due to its solid-state protection and built-in circuit breaker. The ROI arises from reduced unplanned downtime, extended life for essential equipment, and easier system upgrades within Eaton’s Power Xpert ecosystem. Regular inspection of connections and verification of UL/NEC compliance during periodic audits is usually sufficient.
