Eaton SPC120240H2P Surge Protection Device - UL 1449
Part Number: SPC120240H2P
Quick Summary
The Eaton SPC120240H2P surge protection device protects 240V delta systems in industrial facilities from damaging transient surges. Surges from switching events, motor starts, and grid disturbances can cause unplanned downtime and accelerated equipment wear if left unmanaged. This SPD carries UL 1449 certification and UL1283 5th Edition filtering, paired with a rugged NEMA 4X enclosure to perform reliably in harsh environments. With external side mounting and a 10-year warranty, it offers installation flexibility and long-term cost savings while integrating smoothly with panel boards and downstream protection schemes. For engineers and procurement teams, this means improved uptime, clearer compliance pathways, and a straightforward path to scalable surge protection across multiple lineups.

FAQs
External side mounting of the SPC120240H2P enables flexible placement without front-door clearance issues. Ensure adequate clearance for wiring, maintain proper ambient temperature for the enclosure, and follow manufacturer torque specifications for terminal connections. Verify compatibility with existing panel boards and confirm the enclosure rating aligns with environmental exposure in your facility.
120 kAIC indicates the device can safely interrupt surge events up to 120 kiloamps at initiation. This rating provides a robust margin against large transient surges, reducing the likelihood of SPD failure and downstream equipment damage. For critical loads, a higher AIC rating translates to greater system resilience during extreme events.
Yes. The SPC120240H2P is specified for 240V delta (4W+G) configurations and is designed to protect three-phase delta networks with grounded or high-leg arrangements. Its filtering and protective features address common industrial transients encountered in manufacturing, processing, and power distribution panels.
The SPC120240H2P carries UL 1449 certification and UL1283 5th Edition filtering, along with a NEMA 4X enclosure rating. These certifications support compliance with safety and EMI standards, simplify approval processes for electrical installations, and provide assurance of performance in demanding industrial environments.
The 10-year warranty and robust protection reduce unplanned downtime and costly equipment replacements, delivering a favorable total cost of ownership. Routine inspections and periodic wiring checks are recommended, but the device typically requires minimal maintenance beyond confirming secure terminations and monitoring any indicator LEDs during scheduled maintenance.
