Special features
Standard with surge counter
High-current surge protection: The SPD MAX series provides up to 300 kA per phase protection for 230/400 V Wye systems, delivering strong transient suppression. This reduces stress on downstream equipment such as drives, PLCs, and contactors, translating to longer asset life and lower replacement costs in manufacturing lines and panel boards. Compatibility and ease of installation: A single-module design with an internal terminal block simplifies panel integration and reduces installation time, supporting faster project timelines for new builds or upgrades in control cabinets and subpanels. Rugged enclosure for challenging environments: The NEMA 4X enclosure with internal terminal block enables reliable operation in damp or outdoor installations, such as outdoor panels, substations, or covered industrial areas, while maintaining clean wiring. Monitoring and maintenance: The standard surge counter provides visibility into surge activity, enabling proactive maintenance planning and safer commissioning. RoHS compliance and robust certifications: Built to meet RoHS requirements and critical safety standards (UL, CSA), supporting global deployments and regulatory alignment across industrial facilities. Long-term warranty and lifecycle value: A 15-year warranty (20 years with registration) lowers total cost of ownership by reducing retrofit or replacement risk in plant protection schemes, while a proven design streamlines procurement and asset management for electrical protection programs.

FAQs
Install the SPM300400Y3X as a single-module SPD within the protected panel. Connect the L1/L2/L3 lines and the protective grounding conductor to the internal terminal block, then verify the surge counter and status indicators. Ensure the panel permits a NEMA 4X-rated device and follow UL/CSA wiring guidelines for clean, code-compliant installations. Given the 9.3 in depth and 14.91 in width, confirm adequate space and mounting provisions prior to placement.
The Eaton SPM300400Y3X is rated for up to 300 kA per phase, providing robust protection against high-energy transients. It is a single-module SPD designed for 230/400 V Wye systems with 4W+G (4-wire plus ground) configuration, suitable for safeguarding drives, PLCs, and panel equipment from damaging surges.
Yes. With 230/400 V Wye compatibility, a rugged NEMA 4X enclosure, and a surge counter for monitoring, the SPM300400Y3X is well-suited for automated manufacturing lines, control panels, and data-center auxiliary panels where reliability and uptime are critical. Its 300 kA per phase rating supports protection of sensitive automation devices from transient events common in industrial environments.
The device carries UL 1449, CSA Electrical Notice No. 516 Edition 1, and CSA Std. C22.2 No. 8-M1986, among others. These certifications validate safety, performance, and compliance with North American standards, making it suitable for regulated facilities and helping with insurance and maintenance validations for industrial power protection programs.
The SPD MAX series offers 15 years of warranty from the date of delivery, with an extended 20-year warranty available when registered on Eaton’s site. The unit includes a surge counter for ongoing monitoring and maintenance planning, supporting predictable lifecycle costs and easier asset management across facility protection strategies.
