Eaton SPM320600D1U SPD - NEMA 4 w/ internal breaker

Two-module design delivers 320 kA per phase, enabling robust transient energy absorption and proper protection coordination with upstream protective devices. This translates to higher equipment uptime and reduced nuisance trips in manufacturing lines and data-center power rails. Application: ideal for three-phase power distribution feeding motors, drives, and PLC panels. 600 Delta (3W+G) voltage rating ensures comprehensive protection across grounded three-phase networks, minimizing voltage excursions that can degrade sensors, drives, and contactors. Business impact includes improved product quality and reduced unwinding costs in automated lines. Application: suitable for panel boards, switchgear, and process control cabinets. NEMA 4 enclosure with internal terminal breaker supports outdoor and harsh indoor environments, streamlining installation and enhancing safety through contained wiring and quick fault isolation. Business value includes reduced installation time and enhanced code compliance. Application: outdoor service entrances, weather-exposed panels, and wet/dusty plant areas. Standard with surge counter enables proactive maintenance by tracking event counts, aiding in trend analysis and replacement planning. This reduces unplanned downtime and supports reliability-centered maintenance programs. Application: critical process areas and high-load motor suites. RoHS compliant with multiple certifications (UL 1283, UL 1449, CSA) ensures regulatory alignment and environmental responsibility, contributing to safer procurement and long-term compliance. Warranty of 15 years (20 years with registration) lowers total cost of ownership and provides long-term risk mitigation. Application: corporate compliance and long-cycle protection strategies.
