Eaton SPD100600D3N Surge Protection Device - UL 1449

The SPD100600D3N offers a high interrupt rating of 100 kAIC, which translates to superior protection for downstream equipment and reduced risk of expensive repairs after transient events in industrial facilities. This feature directly improves equipment reliability, minimizes production stoppages, and supports safe startup sequences in harsh manufacturing environments. External side mounting simplifies retrofits and new installations by aligning with existing distribution layouts, enabling faster commissioning and fewer enclosure modifications. The NEMA 4X enclosure delivers weather and dust resistance, making it suitable for outdoor panels, damp environments, or exposed electrical rooms, thereby expanding deployment options without compromising safety. With a 600V delta (4W+G) rating and operation at 840 L-G and 840 L-L, the device is well-matched to standard industrial 600V networks, ensuring dependable surge mitigation across three-phase systems. The built-in surge counter provides real-time visibility for maintenance planning and compliance reporting, while the standard feature package keeps total cost of ownership low and simplifies procurement. A 15-year warranty and UL 1449 certification further reduce risk for long-term programs, allowing engineering teams to meet uptime targets and regulatory requirements with confidence. Dimensions 9.5 in length, 5.4 in width, 3.45 in height and a weight of 3.5 lb help ensure proper cabinet fit and installation planning in space-constrained environments. In practice, this means faster deployment, fewer field modifications, and measurable improvements in system reliability across industrial control panels, distribution equipment, and data acquisition racks.
