Eaton SPM400240D1Y Surge Protection Device - UL 1449
Part Number: SPM400240D1Y
Quick Summary
Eaton SPD MAX series surge protection device protects industrial power systems from transient surges in 240 Delta 3W+G networks. Many plants struggle with nuisance surges that damage controls, shorten component life, and trigger costly downtime and maintenance. Certified with UL 1449 and UL 1283, RoHS compliant, CSA-listed, this SPD aligns with rigorous safety and environmental standards. The NEMA 4X enclosure with an internal terminal block simplifies installation in control panels and MCCs, while a two-module configuration supports up to 400 kA per phase. For engineers and procurement teams, the robust warranty—15 years from delivery (20 years when registered)—translates into lower lifetime ownership costs and predictable maintenance. This combination delivers reliable protection and clear business value for modern industrial power networks.

FAQs
Installation begins with confirming the NEMA 4X enclosure suitability for the environment. Mount the unit inside the panel, connect line and load conductors to the internal terminal block, and ensure proper clearance for routing and cooling. The two-module design simplifies wiring; follow Eaton’s installation sheet to maintain 400 kA per phase protection while meeting clearance and grounding practices for safe operation.
The device uses a 240 Delta (3W+G) configuration with two modules providing up to 400 kA per phase surge current rating. It is RoHS compliant and listed under UL 1449 and UL 1283, with CSA recognition. These specs make it suitable for protecting three-phase control systems and MCCs against high-energy transients while meeting safety and environmental standards.
Yes. The SPM400240D1Y comes in a NEMA 4X enclosure designed to resist wind, rain, and corrosion, making it appropriate for outdoor or challenging environments. The internal terminal block simplifies wiring and reduces exposed connections, improving reliability in areas with dust, moisture, or chemical exposure commonly found in industrial facilities.
The unit is UL 1449 and UL 1283 listed, certified by CSA, and RoHS compliant. These certifications confirm safety and performance standards for surge suppression devices, support regulatory approvals for installations, and help ensure environmental compliance across global operations.
The SPD carries a 15-year warranty from delivery, extending to 20 years when registered with Eaton. This long-term warranty reduces maintenance risk and improves total cost of ownership by lowering downtime, preserving critical equipment, and providing predictable budgeting for service life and replacements across complex industrial sites.
