Eaton SPM120240D1T Surge Protection Device - UL 1449

The 120 kA per phase surge capability is the core protection feature, delivering higher energy absorption and reducing the likelihood of downstream equipment damage. This translates to fewer unplanned outages, extended life for drives and controls, and lower warranty exposure in storm or switching transients. The 240 Delta (3W+G) configuration supports common North American industrial systems, enabling reliable protection across motor control centers and panelboards. In a compact single-module form, the device can be installed quickly in new builds or retrofits, minimizing downtime during commissioning. The NEMA 4 enclosure with an internal terminal breaker simplifies wiring, seals out dust and moisture, and allows faster maintenance without removing the unit. RoHS compliance and UL/CSA certifications provide regulatory peace of mind, supporting compliance-driven procurement and audits. The rugged enclosure and documented warranty—15 years standard, up to 20 years with registration—lower total cost of ownership and extend service intervals for critical equipment. This product integrates smoothly with existing Eaton MAX series protections and standard electrical practices, ensuring compatibility and straightforward spare-part sourcing for life-cycle planning.
