Special features
Standard with surge counter
Two-module design delivers 320 kA per phase protection, meaning higher fault tolerance, reduced replacement costs, and improved equipment uptime for critical loads in manufacturing lines and data centers. This configuration supports scalable protection in medium to large electrical panels, enabling fast upgrades as system demand grows while maintaining compact form factor. The product protects 120/208 V Wye (4W+G) networks, ensuring compatibility with common commercial and light industrial power distributions, which minimizes wiring changes during retrofit projects and lowers install time. A NEMA 4 enclosure with internal terminal breaker provides weather resistance and safe, simplified field wiring, improving reliability in outdoor or dirty environments and reducing commissioning risk. Standard with a surge counter, the unit enables proactive maintenance planning, timely replacements, and better asset management across facilities. RoHS compliant and UL/CSA listed protections ensure regulatory alignment and safer procurement decisions for IT rooms, machine shops, and process lines. The warranty offers up to twenty years when registered, reinforcing total cost of ownership advantages and long-term service planning.

FAQs
The SPM320208Y3U is housed in a NEMA 4 enclosure with an internal terminal breaker, making it suitable for indoor and outdoor deployments where dust, water spray, or harsh conditions are a factor. Its two-module design supports compact panel integration and straightforward field wiring, reducing retrofit complexity in data centers, commercial buildings, and light industrial facilities.
A 320 kA per phase rating provides a high level of transient surge protection, meaning larger surge events are diverted away from sensitive equipment. This translates to reduced component wear, lower failure rates, and extended life for connected devices, especially in facilities with frequent switching or high-energy transients.
Yes. The device is specifically rated for 120/208 V Wye (4W+G) configurations, making it ideal for commercial and light industrial power distribution where three-phase systems share a grounding conductor. The 2-module design aligns with common panel configurations, simplifying integration into existing protection schemes.
The SPM320208Y3U carries UL 1449 and UL 1283 listings, along with CSA Electrical Notice No. 516 Edition 1 and CSA Std. C22.2 No. 8-M1986. This certification set supports regulatory compliance, product safety, and reliability in regulated industries, helping with procurement approvals and quality assurances.
The unit is warranted for 15 years from the date of delivery, with a 20-year warranty when registered on Eaton's SPD site. Combined with an integrated surge counter for monitoring and proactive maintenance planning, this translates to lower total cost of ownership through reduced downtime and clearer lifecycle budgeting.
