Eaton SPM300240D3X SPD MAX Series Surge Protector - UL 1449
Part Number: SPM300240D3X
Quick Summary
The Eaton SPM300240D3X SPD MAX surge protection device guards critical electrical systems from transient overvoltages in industrial and commercial facilities. Surges can cause unplanned downtime, degraded equipment performance, and costly maintenance when protection isn't designed for demanding loads. It carries UL 1449 listing and CSA certifications, RoHS compliance, and a 15-year warranty framework that supports reliability across North American installations. The rugged NEMA 4X enclosure with an internal terminal block simplifies installation in damp, dusty, or outdoor environments, while integration with standard 3W+G configurations keeps wiring straightforward. With long warranty terms and clear lifecycle costs, this SPD helps engineers reduce risk, improve uptime, and lower total cost of ownership in power protection programs.
