Special features
Standard with surge counter
The SPM250600D3T delivers 250 kA per phase surge protection in a 600 Delta (3W+G) configuration, providing robust three-phase surge protection that directly reduces the risk of equipment damage and downtime in demanding industrial environments. This translates to measurable uptime improvements for motor drives, PLCs, and sensitive control circuits, while helping facilities meet stringent electrical protection standards. The Max series enclosures are designed for rugged installations; the NEMA 4 rating ensures reliable performance in dusty, wet, or outdoor locations, simplifying retrofits and new builds alike. A standard surge counter offers real-time visibility into protection status, enabling proactive maintenance planning and regulatory compliance without invasive testing. Compatibility with common control panels and Eaton’s wiring practices reduces installation time and errors, lowering project costs and accelerating time-to-protect. All components comply with RoHS, UL, and CSA requirements, addressing procurement and corporate sustainability goals while delivering long-term value.

FAQs
Installers should plan for the unit’s dimensions (9.3 in depth, 14.91 in width, 17.5 in height) and its 50 lb weight within a protected, accessible panel space. Use the internal terminal breaker to simplify wiring, ensure proper enclosure sealing per NEMA 4, and follow the factory wiring diagram for phase and ground connections to prevent mis-wiring and maintain fault protection.
The device provides 250 kA per phase protection in a 600 Delta (3W+G) configuration, delivering fast transient suppression to minimize voltage excursions on critical loads. This performance reduces the likelihood of nuisance trips and sensor misreads, supporting reliable operation of PLCs, motor drives, and other sensitive equipment while aiding compliance with surge protection standards.
Yes. The 3W+G arrangement is specifically designed for three-phase systems with a ground conductor, providing line-to-line and line-to-ground protection. It can be integrated into standard electrical panels that require robust phase protection and ground reference, helping prevent cascading failures in complex automation networks.
The SPM250600D3T carries UL 1449 and UL 1283 certifications along with CSA listings and RoHS compliance. These certifications verify surge suppression performance, electrical safety, and material compliance, ensuring reliable protection in regulated environments and facilitating procurement in industries with strict supplier standards.
Financial value comes from reduced downtime, extended equipment life, and lower maintenance costs. The unit carries a 15-year warranty, with a 20-year option when registered online, plus an integrated surge counter for proactive maintenance. These factors lower total cost of ownership and support long-term uptime and regulatory compliance.
