Eaton SPC120240D7P Surge Protection Device - UL 1449
Part Number: SPC120240D7P
Quick Summary
The Eaton SPC120240D7P surge protection device guards 240V Delta systems and sensitive automation panels. Power disturbances are costly, causing unplanned downtime and accelerated component wear; this unit helps minimize that risk by clamping surges before they reach critical electronics. UL 1449 certified, it is housed in a rugged NEMA 4X enclosure, designed for challenging environments. Its external side mounting simplifies retrofit or new installations in crowded panels, while built-in filtering and a Form C relay enable signaling and remote control. With a 10‑year warranty and compatibility with common Eaton protection schemes, this SPC device supports ongoing uptime, compliance, and total cost of ownership reductions.

FAQs
For optimal performance, mount the SPC120240D7P on an external side, ensure adequate clearance for heat dissipation, and group with other protective devices to minimize wiring length. Use proper conduit routing and follow UL/NEC guidance. This approach reduces risk of thermal buildup and ensures reliable surge clamping during transients.
The 120 kAIC rating indicates high-energy surge handling, enabling the device to absorb large transient events without compromising protection. This translates to fewer downstream component failures, lower replacement costs, and increased uptime for mission-critical automation equipment.
Yes. The unit’s NEMA 4X enclosure provides weather resistance and corrosion protection, making it suitable for outdoor installations and washdown areas. Ensure enclosure integrity and proper sealing at terminations during installation for long-term durability.
Applications requiring reliable signaling and remote control, such as PLC interlocks, alarms, and interwoven control logic, benefit from the Form C relay. EMI filtering improves signal integrity in electrically noisy environments, supporting compliant operation of automated lines and system monitoring.
The SPC120240D7P carries a 10-year warranty and UL 1449 certification, confirming both manufacturer support and compliance with safety standards. This combination lowers lifecycle risk and aids in regulatory and procurement processes for industrial facilities.
