Eaton SPM250480D1V Surge Protector - UL 1449 Listed
Part Number: SPM250480D1V
Quick Summary
Eaton SPM250480D1V surge protector provides robust transient protection for 480V delta systems in industrial facilities. Unprotected equipment suffers downtime and costly repairs from voltage spikes; this SPD MAX module offers reliable protection with an internal circuit breaker. UL 1449 and CSA certifications, RoHS compliance, and a rugged NEMA 4X enclosure ensure performance in harsh environments. Engineered for 480 Delta systems, this device supports safe installations, faster commissioning, and long-term cost savings by reducing fault events and extending electrical asset life. Its modular design and compatibility with the Eaton SPD MAX ecosystem simplify stocking, ordering, and field service. That translates to faster project delivery and fewer late-stage changes in plant protection plans.

250 kA per phase surge protection delivers a higher tolerance to transient events common in industrial environments. The 250 kA rating translates to reduced risk of downstream device damage in motors, drives, and MCCs during large lightning or switching surges. This directly supports uptime and asset protection in 480V delta networks. Durable NEMA 4X enclosure with internal circuit breaker ensures safe, weatherproof operation in outdoor or washdown areas, while allowing field testing and servicing without complete removal. This reduces maintenance cycles and accelerates commissioning in harsh environments. Compatibility with 480 Delta (3W+G) distribution ensures seamless integration with standard plant power architectures and Eaton protection devices, enabling straightforward retrofits and consistent protection across panels and MCCs. Single module, Max series architecture reduces installation complexity and space requirements, with easy wiring, secure mounting, and straightforward replacement during routine maintenance. Warranty and compliance provide long-term value: a 15-year warranty (20 years with registration) alongside RoHS, UL 1449, and CSA certifications, which lowers lifecycle risk and supports regulatory audits. Industry-ready protection strategy: designed for motors, drives, and panels in manufacturing and process facilities, it supports consistent protection across multiple zones and lineups.

FAQs
Install the unit in a 480V delta distribution path with the 3W+G configuration, mount it in a suitable location, and connect per Eaton installation guidelines. Ensure the NEMA 4X enclosure is properly sealed for the environment, verify the internal circuit breaker is wired to the protected load, and reference the product’s UL/CSA notes for compliant grounding and testing procedures.
The 250 kA per phase rating indicates the surge energy the device can safely divert per phase without failing. This high rating reduces the likelihood of downstream equipment damage during large transients, improves uptime for drives and motors, and provides a robust margin for lightning-induced or industrial switching surges in demanding manufacturing environments.
Yes. The device features a NEMA 4X enclosure designed for harsh environments, including outdoor and washdown areas. The rugged construction, combined with internal protection components, helps maintain performance under moisture, dust, and temperature variations typical in plant floors and outdoor substations.
The SPM250480D1V carries UL 1449 and CSA certifications, RoHS compliance, and is compatible with UL 1283 and CSA Std. C22.2 listings. These certifications support regulatory audits, reduce risk in supplier qualification, and align with common electrical safety and environmental requirements in industrial facilities.
The device carries a 15-year warranty from delivery, extendable to 20 years when registered on Eaton’s site. This extended coverage lowers long-term maintenance costs, improves total cost of ownership, and provides assurance against premature device failure, helping justify protection investments in capital projects.
