High-energy surge protection delivers up to 120 kA per phase, providing substantial protection for critical loads and sensitive equipment. This translates to fewer unplanned outages, reduced repair costs, and longer service life for drives, PCCs, and control panels in manufacturing plants and data centers. The enclosure is a rugged NEMA 4 with an internal terminal breaker, enabling outdoor or harsh-environment installations with safer, neater wiring and simplified commissioning. A built-in surge counter adds proactive maintenance insights, enabling you to schedule replacements before failures occur and avoid disruptive outages. The RoHS-compliant design paired with UL 1449 and UL 1283 certifications ensures regulatory compliance and safer operation across multinational facilities. The single-module Max series format simplifies retrofit projects, allowing quick upgrades in crowded, space-constrained switchgear rooms. The 230/400 V Wye (4W+G) rating matches common industrial electrical distributions, delivering reliable protection without sacrificing performance or efficiency. Warranty terms—15 years, extendable to 20 years with registration—lower long-term ownership costs and provide industry-leading peace of mind for asset-intensive operations.

Its compact single-module design simplifies retrofit projects, allowing straightforward integration into standard electrical distribution panels without major enclosure upgrades. Compatibility with Eaton’s SPD MAX series ensures consistent protection across the facility.
This device provides up to 120 kA per phase surge protection, delivering robust defense against transient voltage events that can damage motors, drives, and controls. By limiting overvoltage exposure during spikes, it reduces insulation stress, minimizes nuisance tripping, and lowers the risk of sudden equipment failure, supporting continuous production and uptime.
The unit is UL 1449 and UL 1283 listed and CSA recognized, with RoHS compliance. These certifications confirm safety, performance, and environmental adherence for electrical protection devices used in regulated facilities, helping procurement meet regulatory requirements and corporate compliance programs.
A standard surge counter provides diagnostic data on spike events, enabling proactive maintenance and timely replacements before failures occur. This data-driven approach reduces unexpected downtime, extending asset life and improving overall return on investment by lowering repair costs and optimizing preventive maintenance schedules.
The SPM120400Y3T carries a 15-year warranty from delivery, with a 20-year option when registered on Eaton’s site. This extended coverage lowers total cost of ownership by reducing replacement risk, while access to Eaton’s specifications and support resources helps ensure ongoing performance and rapid issue resolution.
