Eaton SPM300240D4R Surge Protector - UL 1449 Certified
Part Number: SPM300240D4R
Quick Summary
Eaton SPD MAX surge protection device is designed to safeguard electrical panels and automation gear in industrial environments. Unexpected surges can trigger downtime, nuisance trips, and costly outages that disrupt production. By clamping transient voltages at 240V Delta (3W + G) and delivering up to 300 kA per phase, this SPD helps keep drives, PLCs, and sensors online. The unit carries UL 1449 listing and ships in a rugged NEMA 4 enclosure with an internal circuit breaker for added protection and easier maintenance. In practice, it integrates with Eaton’s Power Xpert SPD ecosystem, delivering reliable protection while reducing maintenance frequency and total cost of ownership.

High surge capacity with 300 kA per phase and 240V Delta (3W + G) topology provides robust protection for motors, drives, and controllers, translating to reduced downtime and lower repair costs in busy production lines. This level of protection is especially valuable in environments with heavy motor loads and frequent switching, where unexpected transients can cause expensive faults. The 3W + G configuration supports balanced protection across a 3-phase system, improving overall reliability and system uptime. Installation is simplified by a compact, integrated solution that can be coordinated with Eaton’s SPD Max family, enabling scalable protection without custom engineering. Businesses benefit from fewer nuisance trips and extended equipment life, which lowers total cost of ownership and enhances plant OEE. The NEMA 4 enclosure with an internal breaker provides rugged ingress protection and a safe, local disconnect for maintenance windows. Compatibility with Power Xpert protection schemes simplifies monitoring and event analysis, supporting proactive maintenance programs. The Eaton SPD MAX design also addresses common objections about bulky protection units by delivering a footprint that fits standard main distribution and control panels while maintaining serviceability in harsh environments. This approach aligns with industry best practices for electrical protection in automation-intensive facilities and supports compliant, repeatable installation across multiple projects.

FAQs
The SPM300240D4R is designed for 240V Delta (3W + G) three-phase systems and integrates with Eaton's SPD Max lineup. It fits standard industrial panels, motor drives, and PLC cabinets, enabling straightforward coordination with other protection devices in Power Xpert SPD ecosystems for centralized protection and monitoring.
This device provides up to 300 kA per phase surge capacity, enabling rapid clamping of transient overvoltages from switching events, lightning, or grid disturbances. The higher rating translates to reduced risk of premature component failure in drives, PLCs, and sensors and lowers unplanned downtime in demanding manufacturing environments.
Yes, the SPM300240D4R is UL 1449 listed. This certification confirms adherence to recognized safety and performance standards for surge protective devices, helping facilities meet regulatory and project-specification requirements while reducing compliance risk in regulated industries.
Plan for a footprint compatible with standard main distribution and control panels, noting the unit’s 9.5 in depth, 17.05 in height, 15 in width, and 52 lb weight. The NEMA 4 enclosure with an internal breaker supports rugged environments and simplifies local disconnection for maintenance, while remaining compatible with Eaton’s Power Xpert SPD ecosystem.
By delivering robust surge protection with UL compliance and a built-in breaker, it reduces nuisance trips and prolongs the life of drives, PLCs, and sensors. This translates to lower maintenance costs, fewer production interrupts, and improved overall equipment effectiveness (OEE) in automation-heavy operations.
