FAQs
The SPC100277N5P is designed for external-side mounting in standard control panels and enclosures that house single‑phase 277 V loads. Its NEMA 4X enclosure provides weather resistance for outdoor or harsh environments, while the 100 kAIC interrupt rating supports large transient events. When planning retrofits, verify clearance and wiring space, and ensure compatibility with existing alarm signaling circuits.
Key specs include a 100 kAIC interrupt rating, 277 V voltage rating, UL 1449 certification, and a rugged NEMA 4X enclosure. These features collectively deliver robust surge suppression, withstand high-energy transients, and protect critical loads such as motors and PLCs in manufacturing and process facilities. For best results, confirm system voltage, enclosure mounting, and remote signaling readiness with your control architecture.
Yes. The device uses a NEMA 4X enclosure designed to resist weather, moisture, and corrosion, making it suitable for outdoor panels and exposed installations. Its external-side mounting supports easy integration into existing enclosures without compromising protection. Always ensure appropriate clearance, temperature, and ingress protection in your installation environment.
Eaton backs the SPC series with a 10-year warranty, reflecting its focus on long-term reliability and total cost of ownership. For service considerations, leverage the alarm and Form C relay to enable remote fault signaling, integrate with SCADA or BMS systems, and establish preventative maintenance routines based on surge event logs and diagnostic data.
By delivering high-energy surge protection (100 kAIC) for 277 V single-phase systems, the SPC100277N5P reduces unplanned downtime and equipment damage, lowering maintenance costs over the asset life. The alarm relay enables proactive maintenance and faster response times, while the rugged enclosure supports outdoor deployments, collectively improving uptime, safety, and overall equipment efficiency in automation plants.
