Two-module architecture delivers 320 kA per phase surge current rating, enabling robust protection for critical equipment and significantly reducing the risk of transient-induced failures in manufacturing lines. This translates to measurable uptime improvements and lower repair costs for mission-critical systems. The 127/220 V Wye (4W+G) configuration ensures compatibility with common industrial power distribution, minimizing wiring complexity and enabling rapid deployments in new or retrofit projects. The NEMA 4X enclosure with an internal terminal block provides rugged, field-friendly protection against environmental conditions, supporting safer, faster installations and easier remote maintenance. The standard surge counter offers real-time visibility into surge events, aiding proactive maintenance scheduling and performance verification. RoHS compliance and UL/CSA certifications align with strict regulatory requirements, helping you meet internal standards and supplier obligations while reducing risk in audits. A 15-year warranty (20 years when registered) lowers long-term ownership costs and demonstrates confidence in long-term performance, supporting total cost of ownership (TCO) calculations. Compatibility with Eaton’s SPD ecosystem simplifies lifecycle management and future upgrades, ensuring a scalable path for expanding protection as your facility grows. In practical terms, this model is well-suited for data centers, control panels, motors, and other sensitive loads within industrial environments where reliability, traceability, and compliance drive project success.
