Eaton SPM320600Y3W SPD - UL 1449 Surge Protection Device
Part Number: SPM320600Y3W
Quick Summary
Eaton SPD MAX SPM320600Y3W protects electrical systems from transient surges in commercial and industrial power panels. Without surge protection, equipment downtime and unpredictable outages can derail production schedules and inflate maintenance costs. This unit carries UL 1449, CSA approvals, and RoHS compliance, with a NEMA 4X enclosure for harsh environments. The two-module design delivers robust protection for 347/600 V Wye systems, and with a 50 lb footprint and a 15-year warranty (20 years when registered), it offers a reliable, long-term solution for industrial power protection and panel upgrades.

Two-module construction delivers 320 kA per phase, providing scalable protection for high-energy transients. This translates to reduced risk of equipment damage during motor starts and switching events, avoiding costly downtime in manufacturing lines and data centers. The 347/600 V Wye (4W+G) rating supports common industrial distribution voltages, enabling straightforward panel upgrades without rewiring. A NEMA 4X enclosure with an internal circuit breaker offers weather-resistant protection in harsh environments, simplifying installation in both indoor and outdoor settings and reducing maintenance exposure. A built-in surge counter provides real-time event monitoring, supporting proactive maintenance planning and easier compliance reporting for facility managers. RoHS compliance and multiple certifications (UL 1449, CSA) help meet regulatory requirements while lowering lifecycle risk. The 50 lb unit fits standard form factors and utilities, aiding space planning in crowded control rooms and switchgear areas. The 15-year warranty, extendable to 20 years with registration, translates into lower total cost of ownership and long-term confidence in critical power protection.

FAQs
Install the SPM320600Y3W within standard electrical panels rated for 347/600 V, using its two-module configuration for required protection. The unit features a NEMA 4X enclosure with an internal circuit breaker, requires appropriate bus connections, and should be mounted in a location protected from excessive moisture. Verify clearance, torque connections per Eaton guidelines, and register for extended warranty to maximize long-term value.
The SPM320600Y3W provides 320 kA per phase protection. The two-module design supports high-energy transients common in industrial applications such as motor drives and large transformers, delivering reliable protection across 347/600 V Wye systems. This rating helps reduce equipment damage during switching events and improves overall system uptime.
Yes. The unit is built with a NEMA 4X enclosure, which offers weather resistance suitable for outdoor locations or damp indoor environments. Its internal circuit breaker adds protection against faults, while the RoHS compliance and UL/CSA certifications support safe operation in harsh industrial settings. Plan mounting where ingress protection and ventilation are adequately addressed.
The SPM320600Y3W carries UL 1449 listing and CSA approvals (Electrical Notice No. 516 Edition 1; CSA Std. C22.2 No. 8-M1986), plus UL 1283. It is RoHS compliant, aligning with sustainability and regulatory expectations for industrial protection devices. These certifications validate safety, performance, and compliance across North American markets.
The product ships with a standard 15-year warranty from delivery, with an option to extend to 20 years when registered on Eaton’s site. This extended coverage, combined with a robust 50 lb, two-module SPD and a long service life, reduces total cost of ownership by minimizing unplanned replacements and maintenance downtime.
