Eaton SPM120480D1X Surge Protection Device - UL 1283

The SPM120480D1X delivers a 120 kA per phase surge capacity, providing robust protection for sensitive drives and control electronics in heavy-duty applications. This high-energy rating directly reduces the risk of transient damage during utility or switching events, translating into lower maintenance costs and extended equipment life for machines such as conveyors, pumps, and machine tools. The 480 Delta (3W+G) configuration ensures compatibility with typical three-phase industrial power networks, enabling seamless integration with existing motor control centers and switchgear. Its Max series design emphasizes reliability and ease of service, including an internal terminal block that simplifies panel wiring and future diagnostics, while RoHS compliance supports regulatory alignment and sustainability goals. A rugged NEMA 4X enclosure guards against dust, moisture, and corrosion in manufacturing environments, helping maintain performance in outdoor or harsh indoor locations. The included 15-year warranty (20 years with online registration) adds financial predictability and reduces total cost of ownership, while UL 1283 and CSA certifications confirm adherence to recognized safety and performance standards. Compatibility with standard electrical panels and straightforward replacement cycles help minimize downtime during protection upgrades, and the compact footprint supports efficient space utilization in crowded control rooms. Industry professionals increasingly favor this solution for protecting drives, PLCs, and I/O modules where reliability and compliance directly impact throughput and uptime.
