SPC
The SPC050120N4P delivers 50 kA surge current capacity for robust defense against transient events, protecting critical loads and reducing skip-rated downtime. This protects equipment life and minimizes nuisance trips, which translates into lower maintenance costs and improved productivity for 120 V circuits in commercial and light industrial settings. The NEMA 4X enclosure adds weather resistance and moisture protection, enabling outdoor or damp location installation without compromising safety or performance. With Form C relay output, you gain remote signaling capability for alarms or integration with building management or automation systems, enhancing visibility and responsiveness across the plant floor. External side mounting simplifies retrofits and new installations, saving cabinet space and reducing wiring complexity. A 10-year warranty reinforces long-term reliability, complementing UL 1449 certification for compliant surge protection that aligns with stringent procurement standards. The SPC series is compatible with standard electrical panels and can be integrated alongside other Eaton devices for a cohesive protection strategy and simplified spare-part planning.

FAQs
The SPC050120N4P is designed for 120 V single-phase panels and can mount externally on the side of standard enclosures. Ensure correct phase alignment and connect the line and load conductors per the Eaton wiring diagram. The Form C relay can be wired to an alarm or monitoring system to provide signaling on surge events. Adhere to local code requirements and verify enclosure integrity before commissioning.
This device offers a 50 kA surge current rating with a 120 V voltage rating, designed to protect downstream electrical equipment from transient overvoltages. It protects single-phase circuits typically found in commercial or light industrial panels and helps prevent damage to sensitive components like controllers, drives, and instrumentation during power disturbances.
Yes. The SPC050120N4P uses a NEMA 4X enclosure, providing weatherproof and corrosion-resistant protection suitable for outdoor or damp environments. This robustness reduces the need for additional enclosure protection or indoor-only placement, supporting reliable protection across varied facility locations while meeting regulatory expectations.
The SPC050120N4P is UL 1449 listed, offering trusted surge protection compliance for electrical installations. Its NEMA 4X enclosure adds environmental protection, enabling safer outdoor use. When specifying for projects, these certifications help satisfy safety and performance criteria in procurement and commissioning documents.
The SPC050120N4P carries a 10-year warranty, reflecting Eaton's confidence in long-term reliability. The business case rests on reduced unplanned downtime, lower equipment repair costs, and improved system uptime by protecting critical devices from surges, which translates to measurable savings over the life of the installation and less frequent part replacements.
