Eaton SPC100120N8P Surge Protection Device - UL 1449
Part Number: SPC100120N8P
Quick Summary
The Eaton SPC100120N8P surge protection device delivers robust 120 V single-phase transient suppression for industrial control panels. Operators often battle nuisance surges that accelerate component wear and trigger unexpected downtime; this SPD helps preserve uptime and extend equipment life. UL 1449 certification, a NEMA 4X enclosure, and a 100 kAIC interrupt rating reinforce protection in demanding environments, from manufacturing floors to outdoor panels. With built-in filtering, an alarm, and a Form C relay, it also supports proactive fault signaling and simple integration into existing power architectures. Designed for reliability, it aids in meeting uptime targets while reducing total cost of ownership across critical power rails.

High-energy surge handling is the core feature, delivering up to 100 kAIC. This capability minimizes the risk of catastrophic device failure during severe transients, reducing unplanned outages and warranty claims. In a machine-guarding or process-control panel, this translates to longer component life and stabilised voltages, especially in environments with heavy motor loads or switching loads. The 120 V single-phase design aligns with standard industrial power rails in North American facilities, promoting seamless compatibility with existing panels and equipment. The external side mounting option simplifies retrofits and new installations, reducing wiring complexity and labor time while enabling quick service in cramped or crowded panels. The NEMA 4X enclosure adds moisture, dust, and corrosion resistance, allowing installation in washdown zones or exposed outdoor cabinets. UL 1449 certification confirms adherence to safety and performance standards, easing procurement and compliance reviews. Filtering improves downstream signal quality, and the built-in alarm plus Form C relay supports remote monitoring and fault isolation, enabling smarter maintenance planning. A 10-year warranty provides long-term protection against performance drift, contributing to lower lifecycle costs and predictable budgeting for plant protection programs.

FAQs
Installers should verify 120 V single-phase supply compatibility and plan for external side mounting to simplify retrofits. Ensure space for the NEMA 4X enclosure in the panel, and route signaling wires for the alarm and Form C relay to the control system or BMS. Proper grounding and shielded wiring reduce EMI influence on performance.
A 100 kAIC interrupt rating withstands high-energy surges from motors, welders, and switching events, preventing damage to protected equipment and reducing unplanned downtime. This rating is especially important in facilities with heavy inductive loads or frequent transient events, ensuring continued operation under fault conditions.
Yes. The NEMA 4X enclosure provides robust protection against moisture, dust, and corrosion, making it suitable for washdown areas, outdoor cabinets, and damp environments. This robustness helps maintain protection performance over time and reduces enclosure-related maintenance needs.
The SPC100120N8P carries UL 1449 certification, a key safety standard for surge protective devices. This certification supports compliance with electrical codes and procurement requirements, easing validation during audits and ensuring consistent protection performance in critical systems.
ROI comes from reduced downtime, longer component life, and fewer spares due to transient-induced failures. With a 10-year warranty and easy retrofit via external side mounting, maintenance costs decline, and production uptime improves. Industry data suggest faster fault isolation through the Alarm and Form C relay further lowers service time and operational risk.
