Standard with surge counter
Two-module construction delivers 320 kA per phase protection, providing a robust transient withstand capability. This reduces the risk of damage to downstream breakers, relays, and connected equipment during lightning or utility switching events, cutting downtime and spare parts costs. It integrates into control panels, switchgear, and motor control centers where fast surge events threaten process continuity. 120/208 V Wye configuration (4W+G) enables direct compatibility with common commercial and light-industrial distributions. This compatibility minimizes wiring changes and reduces commissioning time, delivering faster project startup. It is well suited for data centers, manufacturing lines, control panels, and facility electrical rooms where reliable protection at standard voltages matters. Enclosure rated NEMA 4 with an internal circuit breaker provides rugged protection against dust, water, and weather while simplifying wiring and safety compliance. This integration lowers field labor and panel space requirements and enables quicker restoration after a surge event. Applications include outdoor electrical rooms, equipment yards, and harsh production environments. RoHS compliant and UL/CSA certifications ensure safety, regulatory alignment, and a reliable supply chain. This combination simplifies procurement, reduces compliance risk, and supports enterprise-wide standards across multiple sites. Warranty coverage of 15 years from delivery, extending to 20 years when registered on Eaton’s SPD portal, supports a strong return on investment by reducing outages and prolonging critical equipment life.

FAQs
Installation is straightforward in compatible panels. Mount the two-module unit within a suitable enclosure and connect to the 120/208 V Wye supply (4W+G). Use the internal circuit breaker for main protection and verify the built-in surge counter is functional for monitoring. Ensure adequate clearance for heat dissipation and follow local electrical codes.
SPM320208Y1S provides 320 kA per phase surge capability, handling high-energy transients from lightning or switching. This rating protects downstream equipment, fuses, contactors, and sensitive loads by clipping transient voltages and reducing peak currents. For best results, coordinate with upstream protection and maintain recommended enclosure space to avoid derating.
Yes. The unit uses a NEMA 4 enclosure with an internal circuit breaker, delivering weatherproof protection against dust, splashing water, and outdoor conditions. Install in a guarded or sheltered location if possible, and ensure venting is not blocked. The surge counter and status indicators simplify maintenance in challenging environments.
It carries UL 1449 and CSA standards for electrical protection devices, UL 1283, and CSA Electrical Notice No. 516 Edition 1. It is RoHS compliant, supporting environmental and regulatory requirements. These certifications facilitate procurement approvals and reduce risk during audits.
Warranty covers 15 years from delivery, extending to 20 years when registered on the Eaton SPD portal.
