Eaton SPM100240D1X Surge Protection Device - UL Listed

High surge current rating provides up to 100 kA per phase in a single-module design, delivering fast clamping of transients. This reduces nuisance trips and protects upstream equipment from insulator and contact wear, lowering maintenance costs. It is well-suited for delta-connected three-phase systems in manufacturing lines, panelboards, and motor-control centers. Rugged NEMA 4X enclosure with an internal terminal block enhances installation flexibility. The enclosure safeguards the electronics in harsh environments, while the internal terminal block simplifies wiring and improves field serviceability. Installers gain faster commissioning and safer, tidier terminations in both indoor and outdoor-rated spaces. Compact overall footprint with 9.3 in depth, 17.5 in height, 14.91 in width and 50 lb weight provides manageable integration into existing panels. This enables compatibility with space-constrained electrical rooms and OEM enclosures without sacrificing protection level. The single-module design reduces panel space requirements and simplifies replacement. Warranty of 15 years from delivery, extendable to 20 years when registered, reduces lifecycle risk and supports total cost of ownership goals. The product is RoHS compliant and carries UL 1449, UL 1283, CSA certifications, helping compliance teams meet regulatory and procurement requirements. These credentials provide confidence for specifiers and maintenance teams during audits. Industry context and compatibility: The MAX series aligns with typical plant protection architectures, protecting panels, MCCs, and drives where transient events from motors and drives are common. The device supports straightforward compatibility with existing installations due to its standard delta configuration and internal terminal block, reducing retrofit complexity.
