Eaton SPD MAX SPM160480D3V Surge Protection Device - NEMA 4X

The SPM160480D3V delivers a 160 kA per phase surge capacity in a Max series device, offering robust transient protection for critical loads. This rating translates to reduced risk of equipment insulation damage during grid events and switching transients, resulting in fewer unplanned outages and lower repair costs. In typical 480V delta panel boards and industrial controls, that protection translates to measurable uptime improvements and longer asset life.Designed for 480 Delta (3W+G) systems, the unit supports direct mounting in standard panels and aligns with common industrial wiring schemes. The precise voltage rating and grounding arrangement help ensure consistent performance across varied supply conditions, reducing nuisance trips and preserving control system timing.The enclosure is NEMA 4X with an internal circuit breaker, enabling reliable operation in harsh environments and simplifying code-compliant installation. Its rugged build minimizes corrosion and ingress risks in outdoor or damp areas, reducing enclosure maintenance and replacement costs.A built-in surge counter provides visibility into transient events, supporting proactive maintenance planning and asset management. This feature helps maintenance teams justify protection investments by correlating surge activity with equipment wear and uptime improvements.The SPM160480D3V is RoHS compliant and carries UL 1449, CSA Electrical Notice No. 516, UL 1283, and CSA Std. C22.2 No. 8-M1986 certifications, reinforcing safety, reliability, and regulatory alignment. This certification suite supports enterprise-wide compliance programs and vendor qualification standards.With a 15-year warranty (20 years when registered on Eaton’s site), the product reduces lifecycle risk and total cost of ownership. In practice, distributors and engineers gain a proven protection solution that blends performance with installation and procurement convenience for 480V delta systems.
