Eaton SPD100240D4A Surge Protection Device - UL 1449
Part Number: SPD100240D4A
Quick Summary
The Eaton SPD100240D4A surge protection device protects electrical panels by mitigating transient spikes in 240 Delta industrial networks. Unplanned surges can lead to costly downtime, equipment damage, and erratic performance—this SPD helps stabilize critical loads. UL 1449 certification ensures surge withstand performance, while compatibility with Power Xpert SPD and direct bus mounted panels supports compliance and fast deployment. For project teams, it reduces risk and simplifies procurement by aligning with standard 240V delta architectures and 3W+G grounding. Engineers appreciate the compact 3.48 inch depth and 12.05 inch height, as it simplifies panel integration and maintains access to other devices. This makes maintenance crews faster to commission and ensures consistent protection across multi-panel installations.

Surge current
100 kA per phase
100 kA per phase surge rating is the core protection feature. Business impact is a dramatic reduction in transient energy reaching downstream equipment, lowering the risk of PLC faults, drive damage, and motor stalls. Application-wise, it’s well suited to 240 Delta (3W+G) power distribution in industrial panels and line-side protections.\n\nVoltage rating and system compatibility are designed for 240 Delta (3W+G) configurations. This alignment helps ensure correct phasing, grounding, and coordinated protection across three-phase loads, improving overall protection performance and system reliability. Operators benefit from fewer miswired protections and quicker validation during commissioning.\n\nDirect bus mounted panel board compatibility simplifies installation and reduces enclosure clutter. The SPD integrates with Power Xpert SPD accessories for streamlined configuration, enabling faster deployment and consistent protection across multiple panels. This approach supports maintenance planning and spare-part standardization, reducing inventory costs.\n\nUL 1449 certification confirms conformance to recognized surge protection standards, giving compliance teams confidence in performance under surge events. The robust 6.8 lb weight, 12.05 in height, and 7.47 in width support stable mounting and predictable thermal performance. Customers also gain long-term reliability with a proven protection platform.\n\nPower Xpert SPD ecosystem compatibility ensures future-proof protection with existing Eaton products. The device’s compact depth (3.48 in) and mounting options simplify retrofits and new installs alike, reducing labor time and project risk. In practice, you may see measurable reductions in downtime and maintenance costs while maintaining safety margins.
