FAQs
The SPD100480D2N is designed for external sidemount installation external to electrical distribution equipment. It protects 480V delta systems and can be mounted on equipment enclosures or adjacent panels without modifying internal wiring. Use standard side-mount hardware and follow Eaton installation manuals for proper clearances, wiring, and grounding to ensure safe, code-compliant operation.
A 100 kAIC interrupt rating indicates the device can safely interrupt extremely high surge currents without failing or allowing damaging energy to reach protected equipment. This level is suitable for robust industrial environments with frequent or severe transient events, helping to minimize component damage and downtime while meeting demanding protection requirements.
Yes. The SPD100480D2N uses a NEMA 4X enclosure, which provides substantial protection against water, dust, and corrosion in harsh environments. This makes it appropriate for outdoor installations and damp indoor spaces, provided wiring and mounting follow manufacturer guidelines and local codes to maintain enclosure integrity.
The SPD100480D2N is UL 1449 listed, reflecting compliance with safety standards for surge protection devices. It also features a 15-year warranty, offering long-term assurance of performance and reliability. This combination supports maintenance planning, regulatory compliance, and a favorable total cost of ownership for industrial assets.
Plan for external sidemount placement on the distribution system, connect to 480V delta lines with proper L-G and L-L configurations, verify grounding, and follow Eaton’s installation manual. Use the 9.5 in x 5.4 in x 3.45 in footprint to fit the cabinet, and confirm compatibility with 3W+G protection strategy to maximize uptime and asset life.
