Eaton SPD080600D1A Surge Protection Device - UL Listed

80 kA per phase surge capability paired with a 600 V delta rating delivers robust protection for medium- to high-energy electrical systems. This higher energy handling reduces the likelihood of insulation breakdown and uncontrolled arcs during lightning events or switching surges, safeguarding drive panels, transformers, and downstream equipment inside Direct bus mounted panelboards (PRL1a, 2a, 3a, 3e). In practice, that protection translates to fewer unplanned outages, smoother startup sequences, and lower repair costs across manufacturing lines and data-center closets that rely on dependable power conditioning. EMI/RFI filtering provides up to 50 dB attenuation from 10 kHz to 100 MHz, helping keep sensitive drives, PLCs, HMIs, and servo axes stable in noisy electrical environments. Cleaner power signals reduce misfires, jitter, and nuisance trips, enhancing process control and energy efficiency. This level of noise suppression is particularly valuable in mixed-load facilities where motor drives and communication networks share the same bus. Audible alarm with a silence button, a Form C relay contact, and a surge counter with a rest button give maintenance teams immediate fault visibility and straightforward integration with building management systems or PLCs. The audible alert supports on-site quick response while the surge counter provides traceable event data for preventive maintenance. Together these features reduce MTTR and support regulatory audits. Internal integrated mounting and a compact footprint simplify installation and reduce enclosure space requirements on Direct bus mounted panels. The 9.5 in × 5.4 in × 3.45 in enclosure pairs with PRL series cabinets, streamlining wiring, minimizing micro-branch circuits, and ensuring consistent protection across panel bundles in both new builds and retrofit projects. With UL 1449 listing, a 15-year warranty, and a 200 kA short-circuit rating, the SPD080600D1A delivers reliable protection in challenging environments from -40 to 50 C. The combination of rugged construction and formal certifications supports long service life, reduces equipment failures, and aligns with industry standards for electrical protection and circuit control, providing a favorable total cost of ownership over equipment life cycles.
