FAQs
SPD100400Y3L is designed for external side mounting, enabling sidemount installation outside the main equipment enclosure. Follow Eaton’s installer manual IM01005031E for step-by-step guidance, ensure proper clearance for heat dissipation, and connect L-N, L-G, N-G and L-L according to the wiring diagram. The result is a clean, code-compliant protection point that minimizes panel disruption during retrofit.
Key specs include a 100 kAIC interrupt rating, voltage rating of 230/400V wye (4W+G), NEMA 1 enclosure, external side mounting, and operating voltages of 320 L-N, 320 L-G, 320 N-G, and 640 L-L. This combination supports robust surge protection for common industrial power distributions and provides reliable monitoring via the included surge counter.
The SPD100400Y3L uses a NEMA 1 flush enclosure intended for indoor, controlled environments. While it offers strong protection for typical industrial panels and switchgear, applications in harsher or outdoor environments may require additional enclosure protection or a different rating. For clear suitability, assess ambient conditions, temperature, and mounting location against enclosure specifications.
SPD100400Y3L carries UL 1449 certification, a key standard for surge protective devices, ensuring performance and safety under transient events. It also carries a NEMA 1 enclosure rating for indoor serviceability. These certifications support regulatory compliance, reliability, and safer integration into industrial control panels and distribution boards.
The integration of SPD100400Y3L supports reduced downtime by mitigating surge-induced equipment failures and extending asset life. The built-in surge counter enables proactive maintenance, while the 15-year warranty lowers lifecycle risk. With its 100 kAIC rating and standard feature package, maintenance teams can plan preventative checks around surge activity without interrupting production.
