Eaton SPC150120N5P Surge Protection Device - UL 1449
Part Number: SPC150120N5P
Quick Summary
The Eaton SPC150120N5P surge protection device is designed to guard 120 V single‑phase power networks in industrial controls by suppressing transient overvoltages. In critical control panels, a fast surge can trigger resets, damage drives, or downtime; this device minimizes that risk with high-energy clamping and reliable signaling. It is UL 1449 listed and housed in a rugged NEMA 4X enclosure, engineered for harsh environments, with an audible alarm and Form C relay for proactive fault signaling. With a ten‑year warranty and a compact external‑side mounting footprint, it integrates easily into existing panels without redesign, delivering measurable reliability and cost savings.

FAQs
Install the unit on the exterior side of the panel as specified, connect line and load wires per the catalog sheet, and secure the enclosure to maintain the NEMA 4X rating. Verify the audible alarm and Form C relay wiring for remote signaling and integrate with existing control logic or monitoring systems.
The SPC150120N5P provides a 150 kAIC interrupt rating, designed to absorb high-energy transients. It protects 120 V single‑phase controls, PLCs, drives, sensors, and other sensitive electronics in industrial control panels, reducing the risk of nuisance outages and equipment damage.
Yes. The unit uses a rugged NEMA 4X enclosure, allowing installation in harsh environments, washdown areas, or outdoor adjacent spaces while maintaining surge protection performance and reliability.
The SPC150120N5P is UL 1449 listed, ensuring compliance with recognized surge protection standards. It also incorporates a durable enclosure and remote signaling features (audible alarm and Form C relay) to support regulatory and maintenance requirements.
The audible alarm and Form C signaling enable proactive fault management, reducing unplanned downtime. The 150 kAIC protection, 10‑year warranty, and UL listing contribute to lower lifecycle costs by minimizing downtime, extending component life, and simplifying compliance documentation.
