Two-module architecture delivering 320 kA per phase ensures fast surge clamping and fault containment, reducing the likelihood of downstream equipment damage and extending the life of connected drives and controllers. This robustness translates to fewer unplanned outages and lower replacement costs in machine shops and manufacturing lines. The NEMA 4 enclosure with an internal circuit breaker simplifies installation and service in wet or dusty environments, reducing the need for additional enclosure upgrades and enabling reliable protection in indoor facilities or protected outdoor installations. A standard surge counter provides immediate visibility into protection events, enabling data-driven maintenance scheduling and easier regulatory reporting for audits. The 15-year warranty, extendable to 20 years with registration, lowers total cost of ownership by transferring risk and maximizing asset longevity. Compliance with RoHS, UL 1283, UL 1449, and CSA standards reinforces reliability and regulatory alignment across facilities. Dimensional and weight specs (9.3 in depth, 17.5 in height, 14.91 in width, 50 lb) support planning for rack or panel installations while preserving service access and replacement cycles. The SPM320600Y3S is compatible with Eaton’s Max series and 347/600 V Wye configurations, streamlining upgrades and future scalability for automation systems.

FAQs
Install the SPM320600Y3S in a suitable enclosure or panel that supports 347/600 V Wye systems. Its dimensions are 9.3 in deep, 17.5 in tall, and 14.91 in wide, with a listed weight of 50 lb, so plan for proper mounting hardware, support, and service clearance. The NEMA 4 enclosure with an internal circuit breaker facilitates maintenance access and protects against dust and moisture in indoor or protected outdoor environments.
The device uses a two-module design delivering 320 kA per phase, enabling rapid surge energy handling and containment to protect connected equipment such as drives and controllers. This translates to lower risk of downstream component damage during both lightning events and utility transients, reducing repair costs and downtime in critical applications.
Yes. The unit is rated for 347/600 V Wye (4W+G) configurations, making it suitable for three-phase industrial feeders and control panels that require high-surge protection at these voltages while maintaining a grounded reference.
The SPM320600Y3S carries UL 1283 and UL 1449 certifications, plus CSA electrical notices and RoHS compliance. These certifications verify safety, performance under surge events, and regulatory alignment for North American facilities, helping you meet internal standards and external audits with confidence.
The base warranty is 15 years from delivery. If you register the product on Eaton’s SPD site, the warranty extends to 20 years. Registration typically requires proof of purchase and the serial number, after which you gain longer protection against failures and improved asset longevity.
