Eaton SPD120208Y2N Surge Protection Device - UL1449
Part Number: SPD120208Y2N
Quick Summary
The SPD120208Y2N surge protection device from Eaton protects electrical systems from transient surges in 120/208V power distribution. For engineers confronting nuisance spikes that damage drive hardware, PLCs, or motors, downtime and replacement costs are a constant pain point. UL 1449 certification and a rugged NEMA 4X enclosure deliver reliability in harsh environments, while a 120 kAIC interrupt rating provides robust surge handling. External side mounting simplifies integration with existing panels, and the standard feature package helps accelerate commissioning—supporting maintenance budgets and uptime. This combination reduces project risk during retrofits and new builds, making it a practical choice for data centers, manufacturing lines, and facility upgrades where transient protection matters.

SPD120208Y2N is designed for 120/208V wye systems (4W+G), enabling direct protection for motors, drives, sensors, and control panels without reconfiguring distribution. In practice, that means fewer parts, faster installs, and reduced wiring errors during commissioning across data centers, manufacturing lines, and commercial facilities. The device delivers high-energy protection with a 120 kAIC interrupt rating, guarding upstream gear from utility switching transients and fault-induced surges, which translates to lower downtime and longer asset life for critical loads. The rugged NEMA 4X enclosure and external side mounting provide outdoor-ready protection and retrofit flexibility, simplifying installation in cabinets, switchgear, or exterior equipment enclosures. A 15-year warranty and standard feature package further reduce lifecycle costs and accelerate field deployment for engineering teams. Compatibility with existing electrical distributions minimizes risk when upgrading legacy protection schemes while meeting industry expectations for reliability and compliance.

FAQs
Install the SPD120208Y2N using the external side mounting arrangement to attach it alongside or onto the exterior of electrical distribution equipment. Plan for adequate clearance, route leads to L-N, L-G, and N-G terminals, and follow the provided installation manual. The unit’s 9.5 inch depth and 5.4 inch width fit common enclosures, while the 3.5 pound weight supports simple mounting with standard hardware. Confirm compatibility with 120/208V wye systems and ensure proper grounding to maximize surge protection performance.
Key specifications include voltage rating of 120/208V wye (4W+G), interrupt rating of 120 kAIC, enclosure type NEMA 4X, and operating voltages of 150 L-N, 150 L-G, 150 N-G, 300 L-L. It is suitable for commercial and industrial power distribution, outdoor installations, and retrofit projects where reliable transient protection is required for equipment like motors, drives, and control panels.
Yes, the SPD120208Y2N carries UL 1449 certification, confirming compliance with surge protection standards. Its 120/208V wye configuration and external side-mount design are compatible with common electrical distribution equipment found in many facilities, including data centers and manufacturing environments. The 120 kAIC interrupt rating provides a robust protection margin for upstream devices, enhancing overall system reliability.
The SPD120208Y2N comes with a 15-year warranty, reflecting Eaton’s confidence in long-term reliability. Routine maintenance is typically limited to periodic visual inspections and confirming secure mounting and grounding. To maximize uptime, integrate the device into your asset management plan and reference the installation and maintenance manuals for any periodic checks recommended by Eaton.
By mitigating transient overvoltage events, SPD120208Y2N reduces equipment damage and unplanned downtime, extending the life of motors, drives, PLCs, and sensors. The high 120 kAIC rating provides strong surge protection for critical loads, while the external side mounting and standard feature package shorten installation times. Over the lifecycle, this translates to lower maintenance costs, fewer emergency repairs, and a faster return on investment for modernization or retrofit programs.
