Eaton SPM320220Y3S Surge Protection Device - UL 1449
Part Number: SPM320220Y3S
Quick Summary
Surge protection device safeguards industrial panels from transient overvoltages in automation environments. In many facilities, a single surge can trigger costly downtime and damage critical drives, relays, and PLCs. The Eaton SPM320220Y3S carries UL 1449 and CSA certifications and RoHS compliance, ensuring regulatory alignment, while a rugged NEMA 4 enclosure and an internal circuit breaker withstand harsh plant conditions. With two modules and a 320 kA per phase rating, it accommodates demanding power environments and simplifies integration into existing switchgear. The built-in surge counter aids maintenance planning, and the long warranty—15 years (20 years with registration)—adds total cost of ownership benefits for asset-intensive operations.

Special features
Standard with surge counter
High-energy protection with two-module design delivers 320 kA per phase, reducing the risk of equipment damage in high-energy transients and enabling longer equipment life for motors, drives, and controls in demanding industrial environments. This translates to measurable uptime increases, lower maintenance costs, and greater process reliability as surges are intercepted before they reach sensitive components. The 127/220 V Wye configuration ensures compatibility with common plant voltages, simplifying panel integration and reducing engineering time during modernization projects. A NEMA 4 enclosure with an internal circuit breaker provides outdoor and harsh-environment resilience, enabling safer outdoor installations and minimizing enclosure-related leakage or protection concerns. The standard surge counter streamlines diagnostics and maintenance planning, supporting proactive replacements and maintenance windows, while RoHS, UL 1449, and CSA certifications substantiate compliance with global procurement specs. The compact two-module design supports modular upgrades and easier replacement, helping maintenance teams minimize downtime during service windows. A 15-year warranty, extendable to 20 years with registration, further reduces lifecycle risk and total cost of ownership for asset-heavy facilities.

FAQs
The SPM320220Y3S is designed for industrial panels, switchgear, motor control centers, and control cabinets where transient surges threaten sensitive devices. Its two-module configuration and 320 kA per phase rating provide robust protection for drives, PLCs, sensors, and relays, helping minimize downtime and extend equipment life in harsh manufacturing environments.
This SPD carries RoHS compliance and key electrical safety certifications including UL 1449 and CSA standards. These certifications support regulatory compliance for procurement and installation in North American facilities, ensuring reliability and traceability in compliance-heavy environments.
The device operates at a 127/220 V Wye (4W+G) configuration and provides 320 kA per phase surge protection. These specifications align with common industrial power rails, enabling straightforward integration into standard control panels and reducing the need for voltage adaptation or custom wiring.
The surge counter provides clear, at-a-glance diagnostics for surge events, enabling proactive maintenance scheduling. This helps planning teams determine replacement timelines, minimize unplanned outages, and optimize spare-part inventories, ultimately supporting higher plant uptime and lower maintenance costs.
Installers should account for the NEMA 4 enclosure’s suitability for indoor/outdoor or harsh environments and ensure proper mounting within a panel or switchgear. The two-module design facilitates modular upgrades, and compatibility with 127/220 V Wye systems simplifies wiring. Verify RoHS and UL/CSA compliance within your procurement specifications for a compliant, reliable installation.
