Special features
Basic
The 250 kA per phase rating provides substantial protection against high-energy transients, reducing the risk of capacitor failure, contact wear, and control logic faults. This directly translates to less unplanned downtime and lower maintenance costs for panel builders and OEMs deploying in harsh environments. The 120/208 V Wye configuration ensures seamless integration with common electrical distributions in manufacturing floors and data centers, minimizing wiring complexity and retrofit effort. The NEMA 4X enclosure with internal terminal block delivers weather resistance and straightforward field wiring, enabling quick installation and reliable operation in damp or dusty environments. As a basic-type protection device, it offers an economical yet effective solution for standard surge protection needs, while RoHS compliance supports responsible sourcing. Certifications such as UL 1449 and CSA reinforce reliability and regulatory readiness across North American applications. The 15-year warranty (20 years with online registration) helps optimize total cost of ownership for long-life installations, and the robust protective platform supports both new builds and upgrades to existing protection schemes.

FAQs
To install the SPM250208Y1X, mount the unit in a standard electrical panel or enclosure designed for surge protection devices, connect the conductors to the internal terminal block, and ensure proper grounding per local code. The 120/208 V Wye configuration aligns with typical commercial/industrial panels, while the NEMA 4X enclosure provides weather resistance for semi-outdoor or harsh environments. Confirm that the panel rating supports the 250 kA per phase protection and verify the wiring diagram in the Eaton specification sheet before energizing.
250 kA per phase indicates the device’s ability to absorb or divert high-energy transient surges on each phase without failure. This rating translates to enhanced protection for sensitive loads such as PLCs, drives, and data-center equipment, reducing the likelihood of voltage spikes causing damage. The specification aligns with critical-load protection in 120/208 V systems and supports reliable operation during industrial power disturbances.
Yes. The SPM250208Y1X is well-suited for data centers, control panels, and manufacturing lines that require robust transient protection on 120/208 V distributions. Its single-module design and NEMA 4X enclosure simplify integration into existing power rails and harsh environments. With a 250 kA per phase rating and UL/CSA certifications, it provides a proven balance of protection, reliability, and ease of installation for mission-critical infrastructure.
The SPM250208Y1X carries UL 1449, CSA certifications (including CSA standards listed in the product data), and RoHS compliance. These certifications validate electrical safety, surge-protection effectiveness, and regulatory compliance, reducing risk during procurement and enabling easier audit and compliance reporting for regulated industries such as manufacturing and data centers.
Eaton backs the SPD with a 15-year warranty from delivery, extending to 20 years when registered on the Eaton SPD site. This extended coverage lowers long-term maintenance costs and downtime risks, improving total cost of ownership. For procurement, the warranty offers assurance of durability, while the RoHS and certifications support both regulatory compliance and supplier reliability across multiple projects.
