Special features
Standard with surge counter
Two-module design delivers 320 kA per phase of surge protection, reducing the likelihood of transient damage to critical loads. This translates to lower maintenance costs and minimized downtime for manufacturing lines, improving overall equipment effectiveness in panel boards and control cabinets. The 127/220 V Wye (4W+G) configuration matches standard industrial power systems, enabling straightforward integration without complex rewiring or adapters, and lowering commissioning risk for new builds and retrofits. A NEMA 4 enclosure with an internal circuit breaker supports outdoor or harsh indoor environments, simplifying installation in production floors and near equipment bays while maintaining safety and compliance. Standard surge counter enhances fault-traceability, enabling proactive maintenance and data-driven replacement planning. RoHS compliance ensures regulatory alignment across global sites, while UL 1449 and CSA certifications validate performance under stringent standards. The warranty—15 years, extending to 20 years with registration—adds financial predictability and ROI for project stakeholders.

FAQs
The SPM320220Y1S uses a 127/220 V Wye (4W+G) configuration, making it compatible with standard industrial electrical panels and control cabinets. Its two-module design fits common panel enclosures, and the NEMA 4 enclosure supports indoor and outdoor installations. For retrofits, verify that space around the unit accommodates 14.91 in width and 17.5 in height, and confirm that the internal breaker aligns with your panel’s protection requirements.
The SPM320220Y1S provides up to 320 kA per phase protection, delivering fast transient suppression to protect sensitive loads such as PLCs, drives, and instrumentation. This rating supports downstream equipment with high inrush or switching transients, reducing the likelihood of nuisance tripping and extending device life during peak power events.
Yes. The unit is housed in a NEMA 4 enclosure with an internal circuit breaker, designed for rugged environments common in manufacturing floors and outdoor facilities. RoHS compliance further ensures safe operation and regulatory alignment across sites, while the enclosure protection minimizes exposure to dust, moisture, and contaminants.
The device is UL 1449 listed with UL 1283 and CSA Electrical Notice NO. 516 Edition 1 and CSA Std. C22.2 No. 8-M1986, confirming compliance with recognized safety and performance standards for surge protection devices. These certifications provide confidence for procurement, industrial installations, and electrical code compliance across North America.
The SPM320220Y1S carries a 15-year warranty from delivery, extending to 20 years when registered on Eaton’s SPD site. The built-in surge counter aids maintenance planning by tracking events, enabling proactive replacement before failures impact operations. These features help reduce downtime costs and total cost of ownership for panel builders, OEMs, and facilities managers.
