Special features
Standard with surge counter
320 kA per phase protection → High surge handling capacity reduces the risk of damage to critical equipment and minimizes unplanned downtime in demanding environments. Application: panel boards and automation cabinets benefit from robust transient protection without frequent replacements. The two-module design enables scalable protection as systems grow, supporting 320 kA per phase across 127/220 V Wye (4W+G) configurations. NEMA 4 enclosure with internal terminal breaker → Weather-resistant, dust-tight protection simplifies installation in harsh or outdoor-rated spaces. Benefit: easier retrofits and safer field wiring, especially in manufacturing floors and outdoor switchgear. Application: control panels, motor drives, and outdoor assemblies where ingress protection matters.Standard with surge counter → Immediate visibility of surge activity improves maintenance planning and compliance reporting. Application: asset management programs and site commissioning where surge history informs lifecycle decisions. RoHS compliant; UL 1283 / UL 1449 / CSA listed → Regulatory compliance reduces risk and speeds approvals in regulated facilities. Application: data centers, healthcare, and industrial environments that require formal certification trails. Warranty of 15 years (20 years with registration) → Long-term ownership cost reductions through predictable budgeting and fewer replacement cycles. Application: OEM integrations and long-duration deployments in automation and plant protection systems.

FAQs
Install the two-module SPD within a compatible distribution or control panel that supports a 127/220 V Wye setup. Connect conductors to the internal terminal breaker as per Eaton’s wiring diagram, ensuring the NEMA 4 enclosure remains sealed to maintain ingress protection. Verify surge counter functionality after wiring and perform a functional test to confirm proper operation.
For 127/220 V Wye systems, ensure the panel accommodates a 4W+G configuration and supports a maximum surge rating of 320 kA per phase. The SPM320220Y1U is designed for two modules, providing robust transient protection while maintaining compatibility with standard industrial wiring practices and available space in control panels.
Yes, the device’s 320 kA per phase protection and 127/220 V Wye configuration suit critical loads in data centers and motor control centers. The NEMA 4 enclosure offers rugged protection in various environments, while the built-in surge counter supports ongoing monitoring and maintenance planning for uptime-focused facilities.
The SPM320220Y1U carries UL 1449, UL 1283, and CSA listings, plus RoHS compliance. These certifications validate electrical safety, surge protection performance, and environmental compliance. For regulated facilities and projects with auditor requirements, such certification trails simplify procurement, installation, and inspection processes.
The unit carries a 15-year warranty, extending to 20 years if registered on Eaton’s SPD site. This long warranty supports a lower total cost of ownership by reducing replacement frequency and downtime. Combined with high surge protection reliability, the city of maintenance can achieve a favorable return on investment through uptime gains and improved asset protection.
