Eaton SPD100600Y3K Surge Protection Device - UL 1449

Paragraphs are presented in a continuous text format to meet the requested structure. 100 kAIC interrupt rating provides robust transient protection for critical loads in industrial panels, helping prevent unplanned downtime and costly equipment wear. The SPD100600Y3K is designed for 347/600V wye systems (4W+G) and supports 420 V line-to-neutral, line-to-ground, and 420 V line-to-line alongside 840 V L-L operating voltage, giving broad compatibility with common distribution schemes. This combination minimizes the risk of nuisance trips during voltage spikes while preserving control system integrity and protecting motors, drives, and programmable logic controllers. External side mounting simplifies installation and future upgrades by allowing sidemount integration without modifications to the main bus or distribution equipment. That compatibility translates to shorter commissioning times, easier retrofits, and reduced field wiring complexity in crowded electrical rooms. The standard feature package, including a surge counter, enables proactive monitoring and immediate visibility into surge events, supporting maintenance planning and root-cause analysis after events. Enclosure is NEMA 1, suitable for indoor installations in controlled environments and aligns with common facility codes for manufacturing, data centers, and warehouses. The device is UL 1449-listed, reinforcing safety and performance under surge conditions. By delivering a clearly defined 100 kAIC rating, it supports reliable protection for heat-sensitive loads and power supplies while avoiding excessive energy dissipation in the distribution network. Warranty of 15 years signals long-term reliability, reducing owner risk for mission-critical equipment and lowering total cost of ownership. The built-in surge counter provides auditable data, supporting maintenance intervals and evidence of performance during disturbances. External sidemounting also simplifies compliance documentation and inspections, while the compact footprint keeps valuable panel space available for future expansion. In practice, this translates to faster project execution and lower lifecycle costs for electrical protection investments.
